I have an old 3,1 8 core Mac Pro from 2008 that I wrote a lot of music on.
I also have an old 5,1 12 core Mac Pro from 2010 that I’m now trying to load those projects on.
I’ve taken the hard drive (running snow leopard (10.6.8)) out of the 8 core and put in the 12 core and now when I load a project certain plugins don’t load or crash and some plugins are now set to the wrong settings.
I’m taking the hard drive out of the 3,1 machine and putting it in the 5,1 machine. So it’s exactly the same installs and everything as it’s the same hard drive. Only thing different is the machine it’s actually in.
