See this article, which also explains why the command line is not a workaround either.Īpfs_hfs_convert, diskutil apfs, newfs_apfs – fail to work properly First Aid does not work on them, they are all reported as using the case-sensitive variant even when they don’t, and there is no support for APFS as an option in any of the app’s functions. There are multiple issues in Disk Utility’s handling of APFS volumes. This may be fixed by rebuilding the Mailbox.ĭisk Utility – cannot handle APFS volumes Mail shows incorrect numbers of messages in the Unread or Flagged smart mailbox. Mail – incorrect number of unread messages (Thanks to Bart Hanson for reporting this.) This affects its main window, not the draft editor, and is detailed here. Mail displays fonts of certain sizes incorrectly, and uses obsolete HTML markup for certain font sizes. (Thanks to derdennis for reporting this.) There does not appear to be any workaround. Those which had previously been accessible are no longer there. Preview, and other apps which rely on PDFKit, no longer support any items in the Services menu. Preview – loss of all items from Services menu 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 with a Fusion Drive: 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. It has remained unfixed in 10.12.4, 10.12.5, and 10.12.6, although the last of those has brought some changes in the systems responsible.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.

Full details are here, and information about what has changed in 10.12.6 is here. 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 still not been fixed in 10.12.6.

Time Machine and other background activities – irregular and unreliable after long periods of running There is no workaround: printing from Contacts remains partly broken. This was first noted here in 10.12.5, and is unchanged in 10.12.6. Almost any control which you try to adjust after that will result in an unexpected quit: for example, editing the Attributes, or changing the Flip Style. With the uppermost popup menu reading Contacts (for the app-specific print settings), select the Style of Pocket Address Book. Open the Print dialog in Contacts, and Show Details. (Thanks to Richard Petersen for reporting this.)Ĭontacts – unexpected quit from Print dialog The workaround is to disable display sleep if affected, and rely on a screensaver which darkens much or all of the display. This was new with 10.12.4, persisted in 10.12.5, and fixed only for some users in 10.12.6. 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. Note, though, that those are no longer maintained.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. If you are looking for a list of bugs in previous versions of Sierra, that for 10.12.5 is here, 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. Note that bad features, poor interface design, and problems with third-party apps, etc., are listed separately here.
