[MacOS] Solution for Slow Finder Panel

Method-1: Reset OpenAndSavePanel Service

==*(*this is what worked for me)==

I find this solution in reddit post: link, so the steps are the follows:

1. Backup file ~/Library/Preferences/com.apple.appkit.xpc.openAndSavePanelService.plist :

   1 2

   zip "$HOME/Library/Preferences/backup/com.apple.appkit.xpc.openAndSavePanelService.plist-[backup-$(date +'%Y%m%dT%H%M%S')].zip" "$HOME/Library/Preferences/com.apple.appkit.xpc.openAndSavePanelService.plist" (OR) zip ~/Downloads/backup.zip ~/Library/Preferences/com.apple.appkit.xpc.openAndSavePanelService.plist

2. Delete file ~/Library/Preferences/com.apple.appkit.xpc.openAndSavePanelService.plist

   1 2	rm "$HOME/Library/Preferences/com.apple.appkit.xpc.openAndSavePanelService.plist" (OR) rm ~/Library/Preferences/com.apple.appkit.xpc.openAndSavePanelService.plist

3. (Prompt the user to) restart your computer

   1 2	echo "⚠️ Please manually restart your computer now ⚠️" (OR) sudo shutdown -r now

Check the difference:

• after esetting the openAndSavePanel service: gif
