iTunes stutters when in background
Upgraded to Mac OS 10.10.5/iTunes 12.2.x this morning. Now iTunes will not play when the screen saver comes on. Itunes also stutters when I had safari in full screen mode while it was playing but didn't stutter when Safari wasn't in full screen mode but iTunes was not the foreground application. Albeit this is on an older Mac but if the software isn't going to work, my Mac should not be supported by the upgrade.
