- Open Terminal
- Type below commands:
Code:
cd ~
find . -name ".DS_Store" -delete
This will delete all .DS_Store files that manages your individual window settings. Then, execute:
Code:
rm Library/Preferences/com.apple.finder.plist
This will reset your Finder preferences.
I can't speak regarding the resize problems, but when I upgraded from Mojave to Catalina, my Finder window positions and sizes were messed up, and toolbars were appearing out of nowhere; this fixed it. Deleting prefs and .DS_Store files usually fixes these kinds of quirks.
