[Obsidian Dragon]

Just for laughs, I loaded Protools 2020.11 on an old 12" MacBook (i5 with only 8 GB Ram) and upgraded to Big Sur (11.0.1) to see what happens. Avid is clear that Big Sur is not in the system requirements for Protools 2020.11. Nevertheless I did it for the sake of this community.

It installed fine. Started up without any problems. I created a session and imported a WAV and an MP3 file. I did some minor editing. It played back smoothly. So I'd say it was relatively successful.

To be clear, I did not load a heavy session or install any plugins other than what installs with Protools. I just played back from the laptop speakers (no audio interface). So take it with a grain of salt.
