![]() ![]() This appears to have been introduced in 10.11.4, and persists in 10.11.5. Some models, notably MacBook Pro Retina, 13″, Early 2015 (MacBookPro12,1) and possibly iMac Retina 5K, 27″, Late 2015 (iMac17,1), freeze periodically and will either restart automatically, or if that fails they require a forced restart. Sporadic freezing, requiring a forced or automatic restart The only workarounds are to try using diskutil in Terminal, or to use a third-party tool, as described here. In 10.11.5 Disk Utility now refuses to select disks for which it cannot change the partition size. This old bug, which used to result in an error reported as “partition (map) too small”, has been eliminated. This is sporadic and completely unpredictable, but affects a wide range of different apps, and still affects 10.11.5.ĭisk Utility – inability to change partition size of some disks You are typing along happily, with your hands well clear of the trackpad, and suddenly the text insertion point jumps to a different location in the text which you are editing. This is another long-standing bug, which goes back to the early days of Apple’s Magic Trackpad in about 2010. Trackpad – unexpected shift of text insertion point The workaround is to switch to that other app by clicking on its icon in the Dock. I used to think that this was confined to certain apps such as Tweetbot, but it also affects Apple’s Messages app and others, and persists in 10.11.5. When switching between apps by clicking on a window, sometimes the selected app comes to the front and its window jumps to a new position on screen. OS X internals – clicking on a window causes it to jump The only workaround is to set the system sleep time to Never, which also stops hard drives from being put to sleep. This is detailed here, and has been present in 10.11.4 and 10.11.5. On some recent iMacs at least, Power Management ignores any setting to not put hard drives to sleep: when system sleep occurs, the hard drive in an internal Fusion Drive is always put to sleep, regardless of the drive sleep setting. Power Management – hard drives always put to sleep on system sleep ![]() The only workaround is to use a third-party tool such as MacPilot to edit the preferences instead of the bundled pane. 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. ![]() The only workaround is to select a different folder, then to select the correct folder again.Įnergy Saver pane – inconsistencies in controls This long-standing but intermittent bug dates back to Mavericks if not earlier, and I have whinged about it here and here, and listed it as present in 10.11.2 to 10.11.4. When switching folder in the view, the rightmost column being displayed has excessive width, filling the Finder window, its divider being placed incorrectly at the right edge of that window. This can occur when using Finder windows which are set to column view. OS X 10.11.5 has been publicly available for two weeks now here is a list of its bugs of which I am aware. ![]()
