Re: Pro Tools 12 and Mac Pro 2009 (4,1 Nehalem)
It's more an issue of the video card in the Nehalem 4.1 not playing well with the newer Apple drivers in Yosemite than a Pro Tools issue. I have the same MacPro and when I updated to Yosemite the graphics are very glitchy. The meters in Pro Tools will be very jerky looking to the point that the audio peaks are way behind the actual transient attack. I tried a newer 5770 video card like others who posted on this subject to no avail. It just doesn't work right. In the end I had to reinstall 10.8.5 which is time consuming and use the machine for my Avid Media Composer program and bought a new machine for Pro Tools. If you try it you will wish you hadn't wasted your time in my opinion. Just trying to help.
