Has anyone found a work around for using Pro-tools-9 with Maverick? If not what is the best way to go back to Mountain Lion?
I've installed Pro Tools 9 to 2009 imac, 2010 MacBook Pro, 2008 MacPro and latest iMac. All running with Mavericks. Running nicely with no problems.
Macworld wrote an excellent article about how to revert to an older OS.
For as long as you stick with PT 9.05 try and keep the same OS, which in this case should ideally be 10.7.x (Lion)
Mavericks and 9 run fine. Just be sure to back up and update your audio drivers if they're from avid.
