garageband system too slow or system overload -10010
I have a mid-2012 Macbook Pro that's running Yosemite 10.10.2 with 16G RAM and a 498G HD (245G used).
Since a recent update to Garageband, I have been getting the error "garageband system too slow or system overload (-10010)".
I don't really use garageband often, but I like to practice vocals every now and then and then play it back to see where to improve.
Now when I go to play the sound back, I get this error and the program freezes.
I don't know what to do or what is causing it, some help would be great.
Also worth mentioning is that the RAM was just upgraded to 16 from 4 (before the update even the 4 would allow play back).
Thanks in advance.
