I've been running PT 8.0.5 on Lion since a few months after Lion came out with no problems.

Caveat: I was running 8.0.5 on Snow Leopard prior to upgrading to Lion. As I understand it, attempting to install 8.0.5 on a Lion computer that has never run PT before causes big problems.

Also, as written on many other posts, Midi doesn't work in the 8.0.5/Lion scenario. The midi files are moved to the incompatible folder, or some such designation.

I've never found the need to upgrade to Mountain Lion or Mavericks.
