  • This software can be installed ONLY on university-owned equipment.
  • As with any major software upgrade, you should have a good backup before proceeding.
  • For installers only: Joel Ness recommends that, instead of doing the default upgrade, we click on the "Options" button in the hard drive selection screen, and choose "Archive and Install." Archive and Install moves existing system files to a folder named Previous System, and then does a clean (re)install of the Mac OS X software.
