I have a Late-2011 Macbook Air with a 1TB hard drive plugged in with Yosemite installed.
I have Audacity 2.0.6 but recently, it stopped working because it said "Audacity is allready running". I looked at the Activity Monitor, Force Quit screen, etc and see nothing.
Please give me a simple answer because I am 13 years old and I can't understand what the heck is going on with audacity.
If you can help me, then thanks!
