I have the same trouble I have mac intel mountain lion 10.8.2
When I try to upload the song i say AUDACITY QUIT UNEXPECTEDLY click report to see more detailed information and send a report to apple.
I knew I made a mistake when I upgrade to mountain lion. Mac is good but any time you upgrade you asking for troubles.
This doesn’t sound like the problem where Audacity doesn’t open due to plug-ins or due to security restrictions, so I started a new topic.
Please try just double-clicking the Audacity icon from /Applications. If Audacity crashes, please send us a crash report for that problem.
If Audacity opens, try importing your song files one at a time by dragging them into the Audacity window. If Audacity crashes, please send us a crash report for that.
To send us a crash report you can copy the crash report in the crash dialog window then paste it into your reply.
Also please right-click or CONTROL-click over the file > Get Info and tell us the path to the file given in “Where” and the name and extension of the file (for example, new_song22.mov).
If you convert these song files to AIFF in http://sbooth.org/Max/ then import them into Audacity from the same folder as the original songs, do they still crash?
Can you stop the crashes if you reboot the Mac? That sometimes helps.
