1. What Mac Hardware, OSX version & sound card you are using?
Macbook Pro 2.1 (2007 model) running OS X 10.5.8. I run an Mbox 2 Mini and M-Audio Connectiv as well as the internal sound card.
2. If you own/have a Mac, why you have one instead of/in addition to a PC?
Bought it for DJ'ing stability, but it's become my primary machine running Pro Tools 8 LE, Reaper and Reason 5/Record. The only reason I still have a PC is for FL Studio.
3. How long you have been using FL Studio as a registered customer?
Since April 2006. Not sure if that's when I registered, but that's when I bought FL Studio 6 boxed. Had used FL Studio 2 on a friend's machine before that. FL Studio has been my primary DAW up until this year. Still running FL Studio 6 but have demoed every subsequent version thoroughly and will definitely upgrade once it's on the Mac.
