Apple's iCloud isn't able to sync the Finder preferences. However, you can copy/paste the following two plist files to your new Mac.
Copy the following two files to your other Mac computer
~/Library/Preferences/com.apple.dock.plist
~/Library/Preferences/com.apple.finder.plist
Hope it helps 🙂 It does for me, so much, when either moving to a new Mac laptop or when I want the same Finder's configuration on another user account.
