I will assume that you just’re operating Sequoia. In some older variations of macOS, I feel there was a separate Saved Software State for the Finder, as there nonetheless is for different apps, but it surely not exists. So far as I can inform, the window state is now saved within the choice file, though it is laborious for me to see the way it’s encoded. Anyway I am unable to discover another candidates the place that knowledge could possibly be saved.
You would need to give up the Finder earlier than restoring the choice file, after which you possibly can’t use the graphical interface to Time Machine. I suppose the best method is to revive a replica of the file, with out changing the unique, then give up the Finder and use the shell to make the alternative. So if you choose com.apple.finder.plist in a snapshot, then click on Restore and Hold each, you will have a file named com.apple.finder (from backup).plist alongside the unique.
Launch the Terminal app and enter this command:
defaults write com.apple.finder QuitMenuItem -bool YES
Change to the Finder. From the Finder menu, choose Relaunch Finder. The impact of the command is to interchange that menu choice with Give up Finder. Choose it. The Finder ought to give up and never relaunch mechanically.
Now return to Terminal and enter this command:
mv 'Library/Preferences/com.apple.finder (from backup).plist' Library/Preferences/com.apple.finder.plist
Relaunch the Finder by clicking its icon within the Dock. Possibly the window state from the time of the snapshot will likely be resumed. I’ve not examined this and I do not know whether or not it should work.
To revive the Relaunch Finder menu choice, run the primary command once more, changing YES with NO. You must relaunch the Finder to see the change.
Replace
The OP reviews failure with this answer, however I will depart it up so anybody discovering this thread will know that.
