Install with no problem.
I had this great Pro Tools with the small interface Fast Track MKII M-Audio.
I used Protools 7 which is pretty good (at that time I had had with a MBox first generation) and so I installed this ProTools SE.
No problem with Mac OS X Leo, I had to download a small patch update, nothing out of the ordinary
Bef, I am not able to process a file of one thirty without export does not crash.
The Pro Tools 7 that I used a few years ago was a very powerful (too much for my needs), the SE version which supports small M-Audio audio interfaces .. the reverse is true.
The software is completely closed, it is only usable with the tools provided (it accepts nothing else not even RTAS).
In addition he is wallowing on long files (one and half hours of audio recorded to normalize, compress and save) .. Adobe Audition while, under the same conditions on the same machine is doing without any trouble.
In short, it allows a small software to use after installation of the audio interface, but frankly there is nothing transcendent.
A duo Audacity / Reaper (PC or Mac) or Audacity / GarageBand on Mac is light years away.
It's good that it is spun free, but this software and its prestigious name (Pro Tools) should not mislead, it is highly sanitized version which in no case is a criterion to consider when the purchase of the audio interface.
