I have a 13-inch MacBook Pro with 4gb of ram, and I upgraded to Yosemite. It’s running a little slow, but not unusable. I have also reordered a VarioUltra, so I have a similar question. But, I don’t think I’ll have any major problems. I might upgrade, if I think that Braille slows it down any further. Good luck.
