I am almost done creating the installation using the method shared by Hennesie2000, I had included in the "PlatformSupport.plist" the two board ID's, underneath there a list with the mac models supported, 1,1 and 2,1 models are not listed, do I have to include those models also?.
First, a big THANK YOU to Pike and others who have made it possible for me to upgrade my Mac Pro 1,1!
I replaced the graphics card with the XFX HD 6670, which is currently under $70 at Amazon, and while I don't get the immediate boot screen, the card itself works great in both Lion and now the release version of Yosemite (no need for any sort of ktext hacks, just plug and play). The only issue with it is that the risers on the bottom of the card made it impossible to plug into the original graphics card slot, I had to move it up one slot. So it's not running at peak speed -- but that's not a big deal for me, it's still faster than the original card. Hope that helps someone else...
So far so good, but I am running across a weird issue in Yosemite:
When I play MKV files I've ripped from my DVD movie collection, I can hear music, but movie dialogue is either completely absent or very difficult to hear.
I didn't have this issue in Lion, and I *think* I'm only seeing the issue in 5.1-encoded audio. Old movies, comedy specials bought online, etc. sound just fine.
Unfortunately, after booting from the USB, I get a black screen with a whole bunch on words for a few seconds and it disappears, what could possibly went wrong?.
P.D. I had followed in detail all the instructions for Hennesie2000 method.
It looks like the following image "Not the actual capture the image was taken from the internet".
I just tried to take a picture but this time the screen appears just fractions of a second, not enough time to take a capture with my phone, is there another solution Hennesie2000?. I will repeat the process to create the USB installer tonight.
Did anyone manage to have 2 graphic cards running in the MacPro2,1 under Yosemite ?
I have 2 GT610 (1x2GB, 1x1GB)...
Under Mavericks I found a trick (hack) to make them both running.
Under Yosemite no chance...
Cards are recognized by the system but only one could work or even none of the displays showed desktop...
Looking for some help...
I had reinstalled Yosemite, but now I don´t see the letters just the grey screen with the apple logo and no spinning wheel, I can´t pass that stage. I have a genius wireless mouse that I use¨The USB device to connect the wireless mouse is attached to a USB port on the back of the monitor¨, I also have an internal bluray that I had added some time ago.
I had never ecountered any issue upgrading previous OS versions with these devices on the computer. What might be the isse?.
I had downloaded from kickass.to, many people claims to work with their machines, I have no other option here in Ecuador I have to use torrents because the lack of access to a supported computer for Yosemite. I had removed all the hard drives, used another drive for the installation but no luck yet, sorry for the inconveniences that I might cause, I greatly appreciate your time and help.
