I was mixing yesterday for the first time on my new Macbook Pro and PT8 and started hearing audible clicks and pops......at first I thought it was in the recording itself then realized that they were not consistent and had to do with something in the system. On another note my Macbook Pro does NOT have a Firewire 400 port (800 only)......I purchased a cable that was 400 on one end and 800 on the other running from my 002 to my Mac. Would that be causing the problem? Anything else I should be thinking about? Here is my system right now 10.5.6 Mac OS X 2.4Ghz Intel Core 2 Duo 4 GB Lacie Hard drive 200 GB Any input would be greatly appreciated......it is extremely distracting hearing these clicks and pops. Especially when you are trying to edit out any unwanted sounds!
