Goodbye Desktop
If you want to stop anything appearing on your Mac’s Desktop, but want to keep files in the ~/Desktop directory, open Terminal and run the following:
defaults write com.apple.finder CreateDesktop -bool FALSE ; killall Finder
After that you won’t see any icons on your Desktop—no files, no folders, no disks; just the pretty picture.
To reverse the process, run the command again, replacing FALSE with TRUE.
