Why does this still keep coming up, always stopping short of the practical framing of the issue?

Avid's official blessing would mean absolutely nothing in this case. They didn't even try for it, and even if they did and found it to be the MOST stable OS ever released from Cupertino they'd still not support it because it's too old. So pointing to the sign which reads "unofficial" gets you nowhere.

From real world experience, I've found Mavericks to be more stable than ML, and more than Yosemite. It's where I'm staying until PT can get rid of more of the bugs.
