Check out the post "CPU overloading, error -6031 on OSX"

I'm running 6.0.1 on a new dual 1.42 OS 10.2.4 and no problems. The speed is awesome, I've never enjoyed Pro Tools as much!

Likewise here. So far NO problems. I am LUVIN' it! This was an upgrade from my 9600 so it is like night and day faster!

Hi guys, I've got the dual 1.42 yesterday, it works great so far, it looks way faster than the dual 867 that I was using before. The only set back for me was that the screen resolution has less options than the 867, I'm using a Sony Wide 23 inches LCD display and the resolution jumps from 1200x960 streched(weird looking) to 1900x1600, the caracters are either too small or too big. Other than that, I'm a hapy man. Thanks for the info. Marcello
