It looks like so. As i have mavericks 10.9.4 and pt11 supports up to 10.9.3. Im not really sure if my mac came with .4 installed or it was updated as im new to the macworld. I tried to find contact email for Avid but could not find. (I live in Malta Europe so email is preferred than calling:)
In the meantime as suggested here im trying PT10 (although not officially supported) and so far it works. Thanks Guys for all the help!
