    Hi Jeff Mayweather, I want to help you with your question, but I need more information from you. Can you please add details in the comment box? What OS system will you be installing?

    I want to reinstall OS X 10.6 on my Mac Pro.

    Did you make a recovery disc of the 10.6 when you got the system? If not you need to go to a Genius Bar and they can roll it back for you.

  • Jeff Mayweather Oct 01, 2014

    Yes I Have a copy of OS X 10.6!

    You need to have your hard drive backed up separate hard drive or with a provider like Crashplan. This is paramount unless you don't have anything on the current hard drive that you need to keep.

    Once you have everything backed up put the disc in and follow the instructions. It will warn you that you are stepping back. The reason you need everything backed up is because it may not give you the option to just install a new OS but may reset your hard drive.

Mac pro wont start nothing happens power light stays on

this can happen if your hard drive is gone. Start will reinstallation of mac os from your CD etc. first. if that solves the problem Good!, otherwise change hard drive and reinstall mac os. Third reason why your Mac pro will do this is because of messed up mother board which can only be fixed by your local computer store etc.

I am running OS X 10.4.11 and would like to upgrade my operating system?

Please provide more information.
To what would you like to upgrade it?

Since OSX Mavericks was just announced, I'm going to assume that's what you're wanting to upgrade to.

Not all Macs can run Mavericks.

Mavericks Capable Macs

Mavericks, like its predecessor Mountain Lion, requires one of the following Macs with at least 2 GB of RAM and 8 GB of available hard drive space:
  • iMac (Mid 2007 or newer)
  • MacBook (Late 2008 Aluminum, or Early 2009 or newer)
  • MacBook Air (Late 2008 or newer)
  • MacBook Pro (Mid/Late 2007 or newer)
  • Mac mini (Early 2009 or newer)
  • Mac Pro (Early 2008 or newer)
  • Xserve (Early 2009)

If your Mac isn't one of the ones listed above, you won't be able to upgrade.

If you have an iMac, MacBook, MacBook Pro, or Mac mini model that was originally released in Early/Mid 2006, the latest version of Mac OS X your system supports is Snow Leopard.

OS X 10.4.10 Stuck Loop

H MerryAnn
I run Avid on my mac and have not experienced what you describe. Avid uses a lot of memory. The first thing I'd look at is do you have enough memory to run the OS and Avid. If that is OK check your screen res' (the system normally warns you if that is incorrect) If you have the install software try uninstalling and re-install to see if that helps.

It does not sound like a OS problem.
