macOS上的Terminal.app无法保留首选项

Question

I used to work with mac os a while ago an now I am coming back. What I noticed is regular preferences update doesn't work for at least Terminal.app. This happens on any High Sierra.

1. Start Terminal.app
2. Go to your Preferences either through a menu or Cmd-, .
3. Change something, eg use different profile as a default.
4. Quit application
5. Start Terminal.app again. Your preferences changes are reset.

What's going on ? Looks like a bug to me, perhaps I have missed something since Lion release.

Answer 1

It could be that your preferences are "stuck." Preferences in macOS has been broken for awhile now and can sometimes get into a state where the app can't read changes made, or changes never get applied.

Try deleting your ~/Library/Preferences/com.apple.Terminal.plist file along with any com.apple.Terminal.plist.lockfile and com.apple.Terminal.plist.<RANDOM> companion files you find. Restart your system and try it again.

Another way is to look at the ~/Library/Preferences/com.apple.Terminal.plist permissions. You may see something like this

Now if you run something like

sudo chown evgeniy.sharapov:staff ~/Library/Preferences/com.apple.Terminal.plist 

And restart the Terminal.app, it seems to go back to normal and able to save changes in Preferences.
