mac23mac Posted June 26, 2010 Share Posted June 26, 2010 Hi, everybody. I upgraded an old PowerBook 12" from Tiger to Leopard. Things look OK, except that: - sound playback is sluggish - the internal microphone is not listed in System Preferences Is this a known problem? What do you think I should do? Specs: 867MHz, 640MB RAM Thank you so much for looking into this. Link to comment Share on other sites More sharing options...
