So I downloaded Audacity a few weeks ago on my Mac with Yosemite installed, and it was working fine. Yesterday, I started getting an error message that 'Audacity is already running". I have tried un-installing and re-installing the program, searching temp files for a possible lock, closing out everything, restarting the computer.
I’m at my wit’s end. What is weird is that it was working beautifully and then suddenly it wasn’t. I didn’t install anything new or change anything.
Any clues? Please. I hate GarageBand so very much.
Audacity 2.0.6 does not officially support Yosemite, but probably that is not the reason for the problem. There are several posts in the Mac board about this. The general consensus is that your Mac’s temp folder may be too full and that you should try rebooting, which will clear out the temp folder.
If you still can’t make Audacity launch after rebooting, open /Applications/Utilities/Terminal.app. Type:
press ENTER on your keyboard and tell us what that says. That will show us what the temporary directory on your machine is.
Then show us what is in that directory:
ls -la $TMPDIR
If there is a folder in that directory called audacity-, try deleting that audacity- folder. However that folder should not survive a reboot.
If that folder is there after reboot, you may want to open /Applications/Utilities/Disk Utility and try verifying the disk and repairing permissions.
