No, com.apple.finder.plist, anywhere on iMac... why?

While in the finder, press command shift G, copy this line and paste it in. Press return.

~/Library/Preferences/com.apple.finder.plist

That picture is the Go to Folder dialog.

The paths it shows won’t have a Finder property list file as that is the “all users” Library.

You have to look in your user Library, ~/Library/Preferences. That folder is hidden, but you can get there by holding down the Option key and selecting Library from the Go menu in Finder.

Sorry, I went to Go menu in finder but there is no library option

That’s because you did not hold down the Option key.

Did you copy the entire line starting with the "~"?

You're welcome.
