MacOS – Is it bad to stop the Mountain Lion installer halfway through an install

macosupgrade

I already have Mountain Lion. I started installing it again (it warns you that you already have it). I realized I don't need to install it again. The install is halfway finished. Can I just quit the install, or is it actively overwriting files?

Hmm it appears from a screenshot I received Mountain Lion was only downloading and not actually installing:

The solution is to:

  1. Check for unfinished downloads
  2. It will reload everything telling you it's all installed already
  3. The download will reset

Done!
