Hey All, sorry if this is the wrong subreddit to ask this, but I couldn't tell where this belongs.
this is bit of a tricky, but been doing a ton of research on this and from xlr8 your mac website, mac rumors, etc. and found this: http://www.reddit.com/r/apple/comments/1rsp3q/install_mavericks_on_older_mac_pro_11_21_20062007/
Essentially, I'm trying to get my 1.1 from 32bit to 64 bit and then install mavericks/yosemite.
I've followed everything on a video and on the Sixty-Four On Thirty-Two websites (SFOTT) but I've come on a weird problem. I've upgraded my video card to the ATI Radeon 5770 which was flashed for a Mac but doesn't display boot screen, I hold down Option, Command+R or C or anything to choose the USB drive to install mavericks but, I get nothing. Any ideas - besides of course putting in the original video card. When I took it out I was about to toss it and I'm still searching for it to see if anyone has any work arounds. Thanks.
