Have a 2008 Mac Mini that takes 30 minutes to boot up.When it finally boots up to the sign in screen I can log on, but anything I try to do after that brings up the spinning wheel of death. Tried all the various start up options and zapping PRAM to no avail. Won't restart from the start up CDs or Techtool disk. If I connect it to my MacBook Pro it target disk mode, the firewire logo shows up on the MacMini Screen, but the disk does not mount on the MacBook desk top. It was a highly used machine. Any suggestions on what to do? Thanks for the suggestions!
