Hello Everyone, I know this won’t be a recommended practice, but it does work, and I have been pleasantly surprised by the performance and reliablity. But you can turn your Mac Pro 1,1 into a HackPro that will run 10.8 and 10.9. I have an old Mac Pro 1,1 and after much research I made the step to install the Chameleon boot loader and was able to successfully install Mavericks. I did upgrade my Video card from the 8800 to a Radeon 5770 and an Nvidia gfx 620. Also I went from 4 gigs of ram to 16. I am currently able to run the newest version of Final Cut Pro 10.1.1 and have no problems with HD or 4K video. I am currently waiting for my new Mac Pro (Late 2013) to arrive, still 4 weeks out. But when it arrives, I will use the old mac pro as a rendering bay and storage facility for my new Mac Pro. No reason to trash the old beast, if it still can serve a purpose then by all means use it. I do agree if you can afford the newest and best, by all means. But if you are in a situation where you can’t then by all means Upgrade. You can contact me if you need help. I will do my best to help you remotely.
