[QUOTE="immdb, post: 16747, member: 1238"] You can find out if it needs a firmware update at the Apple site. The models are listed showing if they need a firmware update to run OS X. Have you tried zapping the PRAM? Hold Command + option + p + r at startup until chimes. Sometimes it requires holding until the third chime. (I guess third times a charm, er I mean chime)) [/QUOTE]
