I'm sussing out Mavericks for a buddy in Nashville on PT10 Vanilla with a Mac Pro 3.1 and I installed PT 10.3.8 which is what I had handy (my license is for HD). So far I hooked my Zen Studio+ up via USB to replicate his setup sorta since I'm HD5 TDM in a Magma for this Mac Pro (sadly no Thunderbolt on a Cheesegrater) and I'm starting to dig it. I'm finding some of my VIs & plugins are compatible with Mavericks but not ML. I recorded 24 mono tracks and then played those back recording 24 more and never got over 10-11% CPU with no issues at 128 buffer, did both recordings for over an hour. Now my Mac Pro is a 2008 3.2GHz 8-core with 32Gb of RAM and SSDs for the OS, not sure what my buddy has yet but it will be the same when I'm done.

In a week or two I will hook my Magma/HD 5 up and redo some torture testing to make sure it all works for me and I will respond back if there are any issues.
