Last week, Apple released Mac OS Mountain Lion, 10.8. Today I've received a few calls inquiring if it is appropriate to upgrade at this time. While it's always tempting to install a newly released OS version or update, we recommend that it's best to wait upgrading all Mac computers running DAW applications. For example, Avid's Pro Tools will have to go through a rigorous testing and approval process, and while some applications, like Apple's Logic Pro, may be able to run on Mountain Lion, you may have software plugins that are not yet compatible. Or possibly audio hardware drivers that will not yet work with 10.8.
So, it's best to let the dust settle, and just keep working on your system as it currently is. As the saying goes... "if it ain't broke, don't fix it."
