I have a recording studio and want to buy the Mac Pro MA970ll/A which has Leopard 10.5. My Mackie board is Firewired to my PC. The Mackie 1640 has ony been approved (so far) with Leopard 10.4.9.........Is is safe to buy the mac now, or wait to see if /when Mackie is approved for 10.5. Anybody out there using the same setup as I am?
