Is it bad to reinstall macOS?
The main reason most people would reinstall macOS is because their system is completely messed up. Maybe error messages pop up constantly, software won’t run correctly, and other usability issues prevent you from working normally. In extreme cases, your Mac might not even boot.
Does reinstall Mac OS delete everything?
Reinstalling Mac OSX by booting into the Rescue drive partition (hold Cmd-R at boot) and selecting “Reinstall Mac OS” does not delete anything. It overwrites all system files in-place, but retains all your files and most preferences.
