Morning Chaps. As stated in the title, every now and then when I'm playing music through iTunes the playback stutters. I.e stops for a second or two then continues. This happens even when only iTunes is running on the macbook and I have checked for memory/CPU hoggers and there is nothing to suggest that the laptop is under undue stress. I'm hoping you guys can help me out. The specs are in my signature, and the iTunes music files are stored on the 750gb hd in the optibay adapter - not on the SSD.
