Thanks Robert and Philip for your responses.
(Philip), I actually spoke with Take recently through email about the Snow Leapord support, he's actually working on a new software package with an updated BR to go with it, no ETA however. I had a friend running Snow Leapord test out the 7.22 version of BR and all worked great other than the loss of the sound reports output so...... my work around is to install Tiger 10.4 on my new mac lol, as a second partition boot up and have all the options working as intended. My current mixer is a ProMix6 that I use in my bag, and now front runner for my set up, however it's limiters are only for the main outs. I'll just have to be extra careful on the ISO's as you guys explained till I can upgrade or maybe modify my mixer.
(Robert), I was debating for a few days to either save a grand and go with the mac/BR set up, or add in a 744T with my 702T, but I just found more bells and whistles with the cheaper set up, sorry to hear about the 788 so far though, would love to get one myself regardless.
