I have been using Audacity since 2008. Yesterday, using v. 1.3 and Mac OsX v. 10.5.8, Audacity started crashing upon startup. I downloaded v. 2.0.0, but still have the same error message: “The application Audacity quit unexpectedly.” Here is the start of the crash report:

Audacity is crashing while attempting to load an Audio Unit effect. Do you have an AU effect named “AURoundTripAAC” or similar somewhere on your computer?
The places to look are /Library/Plug-Ins/Audio/Components and /Library/Plug-Ins/Audio/Components.
If you can find it in one of those two locations, move it out of the Components folder to somewhere else on your computer, such as the Desktop.

Excellent! That was it. I found it in Library/Audio/Plug-ins/Components. Thanks!
