I just migrated my apps from my MacPro which was running 10.7.2 and PT 9.0.6 to a new MBP Retina 15" running OSX 10.8.2.

Firstly, this was one of the most seamless migrations I've done - I've done a few and they were usually painful.
Even the stuff that isn't meant to work in 10.8 is working thus far.

I can launch ProTools 9.0.6, open sessions, create new ones etc etc but I can't get any audible signals coming out via any source - internal aggregate or my Focusrite Forte.

I am guessing this is an incompatibility with 10.8 and PT9 - no audio.

Should I just get on with it and upgrade to PT10?
I'm not being cheap by using PT9 - I was just wanting to know if I'm wasting my time trying to get it to work.
