That was Tim, this is Ternus: Some first thoughts on Apple’s CEO transition

Two men in dark shirts walking on a paved path surrounded by greenery. One wears jeans and black shoes, the other jeans and white sneakers. They appear to be engaged in conversation, smiling.

Tim Cook didn’t get to be a part of a “thoughtful, long-term succession plan” in 2011. After stepping in for Steve Jobs multiple times during the Apple co-founder’s fight with cancer, Cook became CEO, and Jobs became executive chairman just 43 days before Jobs died. Apple didn’t dictate the executive transition. Jobs’s cancer did.

I get the sense that Cook wanted to give his own successor the thoughtful, long-term plan that Jobs couldn’t give to him. Nearly two years ago, Bloomberg’s Mark Gurman suggested that Ternus could be Cook’s planned successor. By the time the Financial Times reported that Ternus was likely to succeed Cook last November, it was clear things were already headed in that direction. I doubt there was a single person at the March unveiling of the MacBook Neo who didn’t know that John Ternus, who spoke to the crowd, was likely to be Apple’s next CEO.

Tim Cook knows he can’t stay at Apple forever. The longer he lengthened his tenure as CEO, the shorter he risked making the transitional period. I’d actually be surprised if Cook isn’t in the executive chairmanship for a lot longer than people expect. I don’t think he’s ready to put Apple in the rearview—but I do think he’s trying to get the timing on this exactly right.

And here it is: Cook will give Ternus the CEO job in a little over four months. (Wall Street has ten days to digest that news before Apple reports its latest financial results.) Then Cook will become Apple’s executive chairman, able to provide advice and support to his successor while presumably allowing him to forge his own path. Ternus gets a runway, mentorship, and a trusted adviser at a particularly stressful moment. I’m sure Cook wishes he’d been able to talk to Steve Jobs during his first year as CEO.

Oh, and Cook will apparently be taking one very specific job with him to the boardroom, according to the press release:

Cook will continue in his role as CEO through the summer as he works closely with Ternus on a smooth transition. As executive chairman, Cook will assist with certain aspects of the company, including engaging with policymakers around the world.

It doesn’t take a magnifying glass to read between those lines. Cook is keeping one of the stickiest jobs he’s had to do the last decade for himself, for now: connecting with the representatives of various governments in ways that advantage Apple, whether that’s easing China’s worries about Apple’s focus on diversifying its supply chain, or convincing the Trump administration that Apple is investing in the U.S. while also needing tariff relief. Not only does Cook have the personal connections there, but it’s a messy business that perhaps Ternus is best insulated from—for now.

Tim Cook’s legacy

There’s going to be ample time to ponder the highs and lows of the Tim Cook era at Apple. The company is impossibly larger than the one Cook took over from Jobs. The explosive growth of the iPhone, especially from 2014 on, has changed the fundamentals of the company. When iPhone growth finally slowed, Cook swapped in a growing wearables business (led by what I assume is the product Cook is most proud of, the Apple Watch) and a dramatically growing set of subscription services. Those growth lines keep Wall Street happy.

When you’re the CEO, you’re the CEO of the whole company—but I do believe that CEOs come to the job with their own strengths, which reflect on their priorities as CEO. Cook’s focus on efficiency, owing to his background in operations, also served Apple well during this period. Realizing that product margins increase over time, he allowed Apple to sell iPhones at lower prices by keeping older models on sale for much longer.

Cook’s priorities helped make Apple a manufacturing powerhouse, capable of building products nobody else could—at least, until Apple showed the way. But as Patrick McGee so capably showed in his book Apple in China, Apple was also training up China on being a tech manufacturing powerhouse. Between that and Cook’s policy of engaging with the Chinese in order to gain access to the lucrative and growing Chinese market, Cook reaped benefits with the side effect of empowering a global competitor and not engaging with a government whose core principles do not fit with Apple’s.

The same goes for the United States, where Cook has managed to reduce the impact of tariffs by playing nice with the administration 1, making some made-in-the-USA servers and boasting about its investments in American manufacturing while downplaying its commitment to diversity, equity, and inclusion.

John Ternus’s opportunity

For John Ternus, who’s been working at Apple for half his life, to say that this is a huge opportunity is an understatement. Congratulations, dude, here’s the keys to one of the world’s most important and valuable corporations. Don’t break it.

But Ternus’s arrival in the CEO’s office isn’t just an opportunity for him. It’s an opportunity for Apple. Every time a new person takes over, whether it’s in the role of CEO or even just a middle manager, there’s an opportunity for change. Even if you worked for the old boss, once you’re the new boss, you have the opportunity to turn the page. It’s a lot harder for someone to reverse themselves on a decision they made than it is for someone new to come in and see the opportunity to move forward. (Cook re-instituted an employee donation-matching program when he took over from Jobs, just as one small example.)

In spite of its success, or perhaps because of it, Apple has been a company in stasis for 15 or 20 years. When everything’s going great, and all the executives just stick around no matter how rich they get on stock options, it’s really hard to make changes. The arrival of any new person in charge, not just John Ternus in particular, is an opportunity to shake things up. New leaders have the freedom to make their mark. That could be good for Apple.

I’m also struck by the fact that John Ternus comes from a product-focused background. All in all, it was probably for the best that Tim Cook was as different in skill set from Steve Jobs as possible, because that was an impossibly hard act to follow. Cook, as an operations guy, got to put his faith in the product teams that were executing and guided them at a very high level. I think it would’ve been a disaster if Apple’s first post-Jobs CEO had been trying to cosplay as Steve. Cook couldn’t pull off wearing that turtleneck.

But it’s been 15 years, and maybe it’s a good thing for Apple to get a CEO who’s closer to the metal? Ternus knows the ins and outs of product development at a different level than Cook ever could. Given that Apple is, at its heart, a company that makes physical products and sells them, having someone who has spent decades at Apple working on those products feels like an opportunity for a positive change.

The importance of keeping Johny Srouji

As a part of Monday’s moves, Johny Srouji has been named Chief Hardware Officer, reporting to Ternus. This is a new C-suite position for Srouji, previously the senior VP of hardware technologies.

It’s hard to see this move and not consider Bloomberg’s report back in December that Srouji “recently told Cook that he is seriously considering leaving in the near future,” a report defused by Srouji two days later.

Srouji is the father of Apple silicon, and Apple’s chip efforts are one of the company’s greatest assets. When word of Srouji’s potential exit broke, it only underscored to me just how vital Srouji and his team are to Apple. It also struck me that perhaps this was evidence that Apple was negotiating with Srouji in order to retain him, during a period when one of his peers—Ternus—was about to be made his boss.

The moment your boss of more than a decade decides to hang it up seems like a pretty good time to take stock and consider what your own next move might be. If you’re Srouji, you undoubtedly have all sorts of different opportunities out there. Having a fellow SVP like Ternus be promoted over you also has to sting a little bit, even if you didn’t especially want the top job.

You need to retain key employees, and there aren’t many people more key at Apple than Johny Srouji. No matter how it went down, here’s the result: Srouji gets a C-suite title, and he takes over Ternus’s hardware role. Ternus’s lieutenant Tom Marieb is reportedly taking his slot and reporting to Srouji. This is textbook retention, and Apple has to be relieved that Srouji is staying on.

Still, these won’t be the last changes. With Cook on his way upstairs to the boardroom, I would expect many other long-tenured Apple executives to redefine their positions or even depart entirely. Keep in mind, most of these people have been working intensely for decades and have made enough money to retire in style. I have no doubt they do it because they love it, but once the boss changes and some of your old colleagues step away, it’s not the same, is it? It’s a cascading wave of change that is probably going to continue at Apple for some time.

Managing that change, and making it for the better, will be one of John Ternus’s first jobs. At least he’ll have Tim Cook to lean on for advice.

Tim Cook to exit as Apple CEO, replaced by John Ternus

Here’s the big news:

Apple announced that Tim Cook will become executive chairman of Apple’s board of directors and John Ternus, senior vice president of Hardware Engineering, will become Apple’s next chief executive officer effective on September 1, 2026. The transition, which was approved unanimously by the Board of Directors, follows a thoughtful, long-term succession planning process.

Like so much with Apple these days, the details of this “thoughtful, long-term succession planning process” have been broken by the press, primarily Mark Gurman at Bloomberg, so when the actual event occurs it’s not a surprise. Well, dropping it on April 20, ten days before Apple’s next quarterly results, is a bit of a surprise—but really, just the timing. Not the details, all of which were widely anticipated.

Silence! Listen, here’s how to control sound from your devices

Glenn Fleishman, art by Shafer Brown

Every Apple device has opinions about when it should make noise. Some of those opinions are reasonable; others will surprise you at 2 a.m.! If you’ve ever wondered why your iPhone alarm blared right through Silent mode, or why your Mac doesn’t have a Silent mode at all, here’s the breakdown.

Everything that makes noise

Before telling you how to suppress, silence, or control audio output, let’s first look at what might provoke a sound and which settings control whether it’s produced. Then I’ll dig into Silent mode and other volume-control options.

Here’s what can trigger audible alerts across your Apple devices, and what controls each:

  • Notification sounds: Sounds associated with notifications are governed by both Focus modes and Silent mode. You configure which apps can use sound in Settings: Notifications, either globally or on a per-app basis. Settings: Focus: Focus mode lets you choose when to suppress these sounds when the mode is active.
  • Sound effects: System feedback sounds are subject to Focus mode choices on an iPhone or iPad, and to the Alert volume slider on a Mac. Silent mode applies to them on an iPhone, iPad, or Apple Watch.
  • Ringtones: For phone and FaceTime calls, both Focus modes and Silent mode will suppress ringtones.
  • Alarms: Alarms are a wild card. On an iPhone or iPad, you can’t silence them with suppression settings—neither Silent mode nor a Focus mode mutes an alarm. On an Apple Watch, however, Silent mode keeps alarms, well, silent unless you’ve enabled the breakthrough option, discussed below. On a Mac, the alarm sound is controlled by the Alert volume.
  • Timers: Timers respect Silent mode on an iPhone, iPad, or Apple Watch. On Mac, they follow Alert volume.
  • Emergency alerts (iPhone only): Government-originating messages, like AMBER Alerts and public safety notifications, ignore both Focus modes and Silent mode on an iPhone. Apple also offers “Enhanced Safety Alerts” for things like imminent earthquakes, though Apple’s documentation is conspicuously silent on whether these override your audio settings. (Educated guess: yes.)
  • Find My’s Play Sound: If you or someone else triggers Play Sound in Find My for a device, that device always plays the Find My sound. It’s designed to help you find a lost device, so Apple bypasses all silencing. It can also help you find a device taken from you, or freak out the taker.

What the so-called Silent mode actually does

iPad Sounds settings with Silent Mode toggle enabled
Silent Mode on iPad (shown) and iPad suppresses ringtones, alerts, and system sounds but leaves alarms, timers, and media audio alone.

Silent mode is available on the iPhone, iPad, and Apple Watch. When you enable it, Silent mode suppresses ringtones, alerts, and system sounds.1 Silent mode doesn’t disable the audio alarms, timers, music, or video audio—they all play right through it. So do Find My’s Play Sound, emergency SOS sounds, fall and crash detection alerts, and government emergency alerts. Apple’s logic is that these are sounds you either explicitly requested or urgently need to hear.

Apple Watch Control Center with Silent Mode icon highlighted alongside Sounds & Haptics settings showing Silent Mode toggle
You can enable Silent Mode on Apple Watch via Control Center (left) or in Sounds & Haptics settings (right).

Your device may also still vibrate, as haptics are controlled separately in Settings: Sounds & Haptics.

Apple Watch Edit Alarm screen showing Break Through Silent Mode toggle
Apple Watch lets you override Silent mode on a per-alarm basis with Break Through Silent Mode.

Despite this seeming clarity, you will find device-based exceptions:

  • On an iPhone or iPad, a Clock alarm ignores Silent mode entirely—it will always make noise.
  • On an Apple Watch, though, Silent mode does suppress alarms unless you specifically enable Break Through Silent Mode for that alarm.
  • If your Apple Watch is off your wrist and charging, Silent mode is ignored, and alarms always play—the assumption being, I infer, that if you’re not wearing your Apple Watch, you’d want to know when an alarm went off!

How to enable Silent Mode

Each type and some generations of hardware have different pathways or options to manage Silent mode:

  • On an iPhone 15 Pro or later (and iPhone Air): Go to Settings: Sounds & Haptics and toggle Silent Mode on.
  • Older iPhones through the iPhone 15 and 15 Plus: These models have the physical Ring/Silent switch on the side.
  • On any iPad: Go to Settings: Sounds: Silent Mode.
  • On any Apple Watch: Go to Settings: Sounds & Haptics: Silent Mode.

On all of these devices, you can also toggle Silent mode from Control Center: just tap the Silent Mode icon. If you don’t see it there, you’ll need to add it by customizing Control Center.2

Macs: No Silent mode for you

Macs don’t offer a Silent mode. Apple apparently assumes that if your Mac is awake and making noise, you’re sitting in front of it and can deal with it!

Instead, Macs split audio into two buckets. “Sound effects”—Apple’s long-standing term for system feedback sounds, alerts, error bonks, and the like—are controlled in Settings: Sound under the Sound Effects section. You can route them to a different audio output device, and there’s an “Alert volume” slider you can drag all the way to zero to mute them.

Mac Sound Effects settings showing Alert sound, Alert volume slider, and toggles for startup sound, UI sound effects, and volume feedback
The Mac’s Sound Effects settings let you mute alerts independently from other audio output.

Everything else—music, video, app audio—is controlled by the main Output volume, adjustable via the keyboard volume keys or a Control Center slider.

Pump down the volume

One more piece of the sound output puzzle worth putting in place: on an iPhone or iPad, the hardware volume buttons normally control media volume, but there’s a setting in Sounds & Haptics called Change with Buttons that lets them also control the separate Ringtones and Alerts volume. If that’s off, you need to adjust the ringtone and alert volume with the slider in Settings.

On an Apple Watch, which has no volume buttons, you adjust volume in Settings: Sounds & Haptics: Tap the speaker icons, or rotate the Digital Crown when the volume slider is visible.

For further reading

I suffered to understand all the interactions of Silent mode and Focus modes, so you didn’t have to, when I researched Take Control of Focus. This book explains everything you need to know about what produces banners, sounds, vibrations, and more, and how to tune, tweak, and otherwise customize Focus modes to preserve your peace of mind while getting a piece of work done—or even reading a book!

  1. Just to be confusing, Apple calls it “Silent mode” in documentation, but it appears as “Silent Mode” in all appearances in Apple interfaces. 
  2. Adding a control to Control Center varies so much by platform and version that I’m going to tell you to use a search engine to find the correct instructions.

This Week in Apple: A day late and $2,000 short

John Moltz and his conspiracy board. Art by Shafer Brown.

Call the foldable iPhone whatever you want, just don’t call it late for dinner. Also, Apple puts its pinkie down and Microsoft has a great plan to fight the MacBook Neo.

A rose by any other name

The rumor mill continues to work overtime on the foldable iPhone. It almost makes one wonder if they know they don’t get time and a half. Last week brought rumors it wouldn’t arrive until 2027 that were quickly squashed by Bloomberg’s Mark Gurman. This week people are still speculating that production is running into some problems.

9to5Mac’s Chance Miller says “It might be really hard to get an iPhone Fold at launch” because of constraints on quantity.

In addition to these rumored production problems, it might also be really hard to get a foldable iPhone because it’ll cost more than $2,000. And I hate to be the one to break it to you, Chad, but you don’t have $2,000.…

An emerging ecosystem for blind audio professionals

Andrew Leland is an author and audio producer. I interviewed him for my former podcast, Parallel, about his memoir. Now he’s written an excellent, practical piece for the public radio-focused site Transom about working as an audio journalist while blind or visually impaired. It’s a great read for anyone interested in an audio career, but also for employers considering hiring one of us. Andrew has plenty to say about the real-world accessibility of software and hardware tools for audio work:

Especially in the realm of music production, Pro Tools on the Mac remains the industry standard. Andy Slater told me, “I’ve never seen a PC in a recording studio, and I’ve been in a lot of recording studios.” Michelle Guadalupe Felix Garcia, a blind audio engineer based in Sonora, Mexico, co-founded the Audio Accessibility Alliance last year to advocate for inclusion in audio production (and live sound). “A Pro Tools user who’s blind is exactly as capable as a Pro Tools user who’s sighted,” she told me, echoing sentiments from numerous other blind professional producers and engineers I spoke to.

He also heard about how switching from PC to Mac is different for blind users:

After months of false starts, KALW eventually connected Rachel Longan with Felix Garcia, the blind engineer, who wanted to teach her Pro Tools, but Longan didn’t have access to or experience with a Mac. The differences in screen-reading metaphors on Mac vs. PC are significant, and require far more adjustment than that switch does for a sighted user.

Leland’s article gets real when it comes to problem-solving and challenges for blind producers, and he reminds us just how much of the process involves creatively hacking solutions to meet very specific needs. It’s a long, detailed piece with a ton of resources and tips.

Solving the ‘problem’ of MacBook Neo’s popularity

Macbook Neo in a fruit bowl

The MacBook Neo is apparently a big hit. So big that Apple is reportedly ramping up production.

Now the bad news: Since the MacBook Neo is powered by the A18 Pro chip from 2024’s iPhone 16 Pro, a product that’s been discontinued, there is likely a finite number of chips available for MacBook Neo production. Which is why, as reported by Tim Culpan, Apple faces a dilemma, namely: What happens when it runs out of chips to use in the MacBook Neo?

This is a really juicy question. If Apple’s hottest new Mac is limited by the number of A18 Pro chips available, there are only so many MacBook Neos that Apple can possibly sell. And if the chip isn’t being made anymore, what can the company do?

While we are all left puzzling this one, I don’t believe that this is as much of a dilemma for Apple. Even if Neo sales are higher than forecast, I do not believe that Apple simply never imagined that it might have a hit product on its hands! If there’s any company that believes in its own greatness, it’s Apple, which is why I’m pretty confident that Apple’s MacBook Neo strategy always came with a contingency plan for runaway success.

What we don’t know is what that contingency plan is. One possibility is that it would go back to its chipmaker, TSMC, and beg to get some space to build some fresh A18 Pro chips. This doesn’t make sense for a few reasons. Apple’s not using this particular TSMC chip process anymore, and TSMC’s capacity is likely sold out with business from other partners. Beyond that, the profit margins built into the MacBook Neo are based on odds and sods from the high-volume iPhone 16 Pro, not fresh new chips baked just for the MacBook Neo. If Apple asks TSMC to fire up the A18 Pro forge again, one of the main methods of making the Neo affordable disappears.

Short of there being a Mystery Chip out there that we don’t know about, I have to assume that the most obvious solution is the right one: Apple has probably always intended to replace the A18 Pro MacBook Neo with an A19 Pro model as soon as it begins scraping the bottom of the A18 bin.

Another part of Apple’s Neo strategy is a reusable design. I have to believe that the MacBook Neo was specifically designed to be updated to a new chip at very little extra cost, because every time you do major product redesigns, margins go down. That MacBook Neo was designed to last four or five years, at least, with different chips sliding in, probably once a year.

Putting a newer chip in the MacBook Neo is the obvious solution. Now, if MacBook Neo sales really are wildly beyond Apple’s greatest dreams, perhaps the company is scrambling to get an A19 Pro model ready to go. But it’s a matter of advancing an anticipated time-frame, not inventing a strategy out of nowhere. (And again, it’s a good problem to have!)

I’ve seen various arguments against this approach, but I don’t think they hold water. Will people who bought an A18 Pro MacBook Neo be bent out of shape if a newer, faster model gets released six or nine months later? I’d guess that most of them wouldn’t notice and wouldn’t care, and there are always people who are put out when new computers eclipse the one you just bought—that’s life. Would Apple risk losing the momentum of its new, hit product because a few people had their feelings hurt because Apple released a newer version of the MacBook Neo? That’s a hard no.

Another argument is that, essentially, Apple can’t release a new generation of MacBook Neo just six or nine months after it released the last one! Apple has repeatedly shown that it’s willing to ship two versions of the same product in the same calendar year—and may be about to do it again this year with the M5 and M6 MacBook Pro. Yes, it’s unorthodox, but the MacBook Neo is also a really weird new kind of Mac, and maybe the rules are different for a computer like this.

Would Apple even make a big deal out of such a move? Updating some or all MacBook Neo models to a new chip would probably amount to nothing more than a press release. Sites like this one would certainly notice and cover it in detail, but I’m not sure anyone else would notice or care.

I do wonder if Apple might extend the life of the A18 Pro model by splitting the MacBook Neo product line in two. Before the bin is entirely empty, perhaps it could upgrade the $699 model to the A19 Pro while continuing to sell the remaining A18 Pro chips in the $599 model. Then, once there are no more A18 Pros to be sold, the A19 Pro could move down on the price list. These are spec changes that we’d notice, of course, but they probably wouldn’t affect the trajectory of the MacBook Neo in the slightest.

What I don’t expect Apple to do is allow the Neo to lose its momentum by making it unavailable for some period of time while it works on its chip shortage. If that means eating into margins, it’ll do that. If that means making a quick chip change, it’ll do that. But Apple strikes me as a company with a killer instinct, and it knows it’s taking the entire cheap PC laptop market to the woodshed right now. I don’t think it’s going to pause for a moment.

Well, maybe for a moment. It should pause just long enough to ensure that the bin of A19 Pro chips is nice and full, so it doesn’t get into this situation again next year.

The iPhone 4 was scandalous, but influential

A man in a black turtleneck and jeans stands on stage, gesturing with a remote in front of a large screen displaying a minimalist design with a vertical bar and circle.

Quick—what’s the most important iPhone ever? The original started it all. The iPhone 6 Plus brought in large sizes for the first time. The iPhone X redefined the phone for a new decade.

But there’s also a strong argument to be made for the iPhone 4, which debuted in spectacular and infamous fashion, generated one of Apple’s most remarkable controversies, and also ended up being one of the most influential iPhones in terms of design.

Most important? Well, maybe. But there’s no doubt that the iPhone 4 is the most interesting iPhone ever.

Amazon acquires Apple’s satellite partner

Amazon:

Today Amazon.com, Inc. and Globalstar, Inc. announced that they have entered into a definitive merger agreement under which Amazon will acquire Globalstar, enabling Amazon Leo to add direct-to-device (D2D) services to its low Earth orbit satellite network and extend cellular coverage to customers beyond the reach of terrestrial networks. In addition, Amazon and Apple announced an agreement for Amazon Leo to power satellite services for iPhone and Apple Watch, including Emergency SOS via satellite.

This deal had been recently rumored. Amazon acquiring Globalstar gives it a leg up in its attempt to take on Starlink, which is the biggest player in this space. But Apple previously sank a billion-dollar-plus investment into Globalstar, whose system underpins its satellite features.

That stake seems to have bought Apple some assurances, including support for not only current but future devices. The ongoing question for Apple’s satellite features is whether users will ever end up paying for them, something that the company has been happy to continually kick down the road. It’s possible the deal is structured in such a way that Apple doesn’t have to pass on the cost to its users, at least for some period of time, but we’ll see what happens this year when the latest round of iPhones comes out.

As for Apple getting in bed with one of its competitors, Amazon is hardly the only other major tech company that Apple now has a close tie to: we know it’s using Google’s Gemini for its forthcoming AI models and, of course, it’s long depended on components made by Samsung. As tech companies get larger and larger, it’s harder and harder for them not to be collaborators.


Is it possible that Apple could run out of MacBook Neos? What’s Apple’s smart glasses strategy, really? We tackle both questions, discuss Jason’s new UWB smart lock, consider the shape and name of the folding iPhone, and more!

Change what Time Machine backs up

Glenn Fleishman, art by Shafer Brown

Time Machine used to be a mess. I would try it with each new macOS release, get frustrated, and give up. My incoming email from readers was sometimes dominated by Time Machine problems, particularly when Apple transitioned from HFS+ to APFS as the Mac’s default startup volume file system. At one point, Time Machine volumes had to be formatted as HFS+ even after APFS became the default startup volume format.

Which is why I’m so pleased that Time Machine generally—generally, mind you—now performs as I would expect as part of my backup-and-archive systems.1 I use Backblaze for encrypted Internet-hosted backups, Carbon Copy Cloner for nightly local clones, and Time Machine for continuous archiving and backups. I also use Dropbox and iCloud Drive for nearly all of my documents.

Often, however, I want to exclude something—or a lot of somethings—from Time Machine. A file or folder is too big (like Parallels virtual machines), a volume contains a clone of another volume (and thus should be ignored), or some data changes so frequently that it’s not ideal to archive using Time Machine.

Here’s how you can control what Time Machine archives.

Via the main System Settings interface

Screenshot of Time Machine's Exclude from Backups list showing volumes and folders excluded.
Use System Settings to exclude files, folders, or volumes from Time Machine backups.

Open System Settings and go to General: Time Machine. Click Options. The Exclude from Backups list shows everything you’ve added, and anything Apple has included. You can drag items in or click the + (plus) icon to open a file or folder (or volume) selector. Select an item and click – (minus) to remove it.

As you can see from my list, I have many external volumes, and all of them are excluded from Time Machine—all external volumes are added to this list by default, and I’ve left it that way. After many, many hard disk drive failures, including a mirrored RAID, I no longer own enough local capacity to back up all my volumes. I put less-critical files on external volumes and rely on Backblaze.

You may also note that a couple of external volumes have Time Machine icons. Those are included in Time Machine by default, and if you select one, the – (minus) icon is grayed out. Typically, the only entry besides those volumes Apple automatically includes is /Users/Shared/adi, which is related to Apple’s digital commerce—that folder can be removed from exclusions, but I don’t know any good reason to.

Dial in your Time Machine exclusions

Screen capture of command-line tmutil session showing excluded volumes one line at a time
You can use tmutil on the command line to get quick answers about what Time Machine will back up or exclude.

If you’re comfortable with the command line, you can also get to know tmutil, which provides text-based control over the same features presented in the Time Machine settings, plus quite a lot else. (In all of these examples, replace /path/to/item or similar with the actual path, of course!)

For instance, if you want to exclude a file or folder, but also may want to move that item later, use:

tmutil addexclusion /path/to/item

Wherever you relocate that item to, the exclusion follows. Or, if you want to use a fixed path and make sure it is invariant, same as the Exclude from Backups, use:

sudo tmutil addexclusion -p /absolute/path/to/item

The sudo command will prompt you to enter an administrative password because it requires elevated system privileges. The -p flag forces the time machine to excluse a path rather than a file.

A neat tip, if you didn’t know it: you can use the Finder to copy absolute paths for items:

  1. In the Finder, select a file or folder.
  2. Hold down the Option key and choose Edit.
  3. Note the Copy “name” as Pathname option: choose it. You can also press Command-Option-C.

The Clipboard stores a path that can be quite short for a local volume, or verge on the absurd for files or folders on iCloud Drive, Dropbox, Google Drive, or other cloud-accessible systems. For instance, take a gander at:

/Users/glenn/Library/Mobile\ Documents/com\~apple\~CloudDocs/Aperiodical\ Projects\ \(iCloud\)/Flong\ Time\ No\ See\ Book/Figures/01\ Flong\ Time/flongs-per-year-chart.png

If you’d like to use the command line to check on items that are excluded or included, you can use:

tmutil isexcluded /path/to/item

You can use shell-based wildcard expansion, too, so if you did a lot of fussing with inclusion and exclusion in nested folders, you can enter the first part of the path, like ~glenn then use ./* to get a list with [Excluded] or [Included] before each directory at that level of the path, like tmutil isexcluded ~glenn/*.2
