Finder
It can be valuable to know how to restart, run a command, and open an app using Terminal, AppleScript, and different methods in the Finder.
This update does fix some old bugs, but here’s a list of those which remain. Updated frequently.
Sierra brings undocumented weirdness to the Finder, with a folder that is, but it isn’t, and improved Finder aliases, which don’t work as well. Yet.
Maximise a List view window in Finder, and it should expand to accommodate the contents. Only sometimes it doesn’t.
A rolling list of bugs which remain in Sierra 10.12.1, including those in Finder and Console.
This list will be maintained throughout this initial release of macOS Sierra. There are still some golden oldies to enjoy.
A curiously impossible problem with Finder sidebars, and Apple’s software success story which shuns it own App Store.
Which Finder Sync Extensions are enabled on your Mac? Are any of them malicious?
With only one bug definitely fixed in 10.11.6, out of those recorded for 10.11.5, this update looks rushed. But the jury’s still out regarding freezing.
