I have just bought a Mac Pro Quad Core 3,2 GHz with SSD for OS and 2 x 1 TB drives, 6 GB ram. I've also bought an Echo Audiofire 12 about to arrive any day now. I have downloaded and installed Logic Pro 9 from Appstore. I intend to buy a few Waves plugins and Toontrack Superior Drummer 2.0 soon. At the moment I use Montain Lion, but judging from what I read in forums it seems a little unstable. I read alot about problems with Waves and Logic. Is it better to downgrade to Snow Leopard at the moment?
