These are long-standing issues which date back to El Capitan. The only way to prevent hard disks from being put to sleep is to prevent system sleep altogether. Further details are here.Ī further bug affects some models, including the iMac17,1: irrespective of the setting to put hard disks to sleep (ticked or not), system sleep invariably puts hard disks to sleep. The features available in the Energy Saver pane of System Preferences are inconsistent between Macs, and incomplete, for example not providing a separate control slider for system sleep on some hardware. I had originally thought that it might have been fixed in 10.12.4, but it remains.Įnergy Saver pane – inconsistencies in controls, and misbehaviour on some models This bug was reported to Apple in February 2017.

The only solution is to restart the affected Mac. If you’re unsure whether backup irregularity is the result of this bug, use DispatchView (in Downloads) to check. The most obvious symptom is that scheduled backups stop, becoming very irregular. Macs which are left running continuously for more than about 7 days are liably to develop this. The long-running bug affecting undocumented systems in macOS which schedule and dispatch background activities, most notably including Time Machine backups, has not been fixed in 10.12.4. Time Machine and other background activities – irregular and unreliable after long periods of running (Thanks to Richard Petersen for reporting this.) The workaround is to disable display sleep if affected, and rely on a screensaver which darkens much or all of the display. So far the only way to restore a normal image on the internal display is to restart. Although the external displays wake normally, the iMac display does not.

Full details are on jamf Nation.ĭisplay sleep – multiple display setups may not wake properly after sleepĪ few users, mainly with iMac 5K models, are reporting that allowing display sleep with one or more external displays connected causes problems when waking.

This may relate to a failure to complete the firmware update to the Touch Bar.

Suggestions for dealing with this are to restart into Recovery mode, open Disk Utility, and run First Aid on the startup disk, but some Macs have had to be set up from a fresh install of Sierra. This seems less likely when updated using the downloadable installer from here. There are reports that some users with the new MacBook Pro models with a Touch Bar are discovering their Macs are suffering kernel panics, or even getting trapped into an infinite boot loop, after updating to 10.12.4 through the App Store. Touch Bar firmware update – Kernel panics and infinite boot loops on some MacBook Pro models with Touch Bar Note, though, that those are no longer maintained. If you are looking for a list of bugs in previous versions of Sierra, that for 10.12.4 is here, for 10.12.3 is here, for 10.12.2 is here, for 10.12.1 is here and for 10.12 is here. This list is no longer maintained: please refer to that last for the latest information. Note that bad features, poor interface design, and problems with third-party apps, etc., are listed separately here.įollowing the release of Sierra 10.12.6, this list has been superseded by the new list for 10.12.6.
