- macOS Finder misbehaving, unresponsive, crashing
This occasionally happens after upgrade. The behavior has been observed in macOS High Sierra and, earlier, in OS X Yosemite 10.10x series.
Solution: On Finder, press Command+Shift+G and go to
~/Library/Preferences/
Locate the file “com.apple.finder.plist” and delete it.
The alternative is to delete the file from the commandline or Terminal:
~/Library/Preferences/com.apple.finder.plist
Reboot the machine afterwards. Or from the commandline:
sudo shutdown -r now "Restarting Now"
- Display of “?” after failed upgrade
Solution: (Re)install using full macOS (macOS High Siera 10.3). Steps:
1. format medium (USB drive with at least 8GB) on MacOS Extended using Disk Utility
create bootable
2. mount a full version of the new macOS version and from there, issue a command similar to this:
sudo << /Applications/Install\ >> macOS\ High\ Sierra.app/Contents/Resources/createinstallmedia -- volume /Volumes/UNTITLED && say Boot Installer Complete
For old machines, you may use High Sierra patcher.
3. Boot medium with Options pressed.
