[QUOTE="Max Warasila, post: 91091, member: 3845"] Re: MacBook Pro Processing Bandwidth Reality Check I used to record 16 channels off an old board into an 2009 MacBook Pro, just into Logic at a friend's gigs. It would consistently complain about the drive being too slow after 30 minutes depending on what else I was doing on the computer at the time.
