I'm sure that you have reasons, but they're not obvious to me, so why do you run Audacity within CrossOver, rather than running Audacity for your OS ? For example, is the Linux version of Audacity problematic with your distribution, or is your Mac's processor or OS version a constraint?
I run some old Windows apps within CrossOver because they're commercial and I can't justify buying OS X versions, but Audacity is free open source software. I'm asking because it might be instructive; I'm not being judgmental.
