Unite 5 - Turn Web Apps into Supercharged macOS apps

So my iMac’s Ethernet port stopped working…

Last night my iMac’s Ethernet port stopped working. Turns out it seems to have been because of a bad, silent security software update from Apple. Just delightful.

More info here and on this MacRumors thread—the update seems to have been pulled and the fix appears to be to reinstall /System/Library/Extensions/AppleKextExcludeList.kext from a backup. I solved the problem by biting the bullet and installing the 10.11.4 beta.

Thanks to reader Nico Rohrbach for the pointer.
