I think it's a 2008 / 2009? It was friends laptop. He left it with me years ago when he upgraded his laptop and was moving out of the coutnry. So it sat in my closet for years. lol Cleaning house now I want to get rid of it. He doesn't want it. I want to just donate or give it away. However, I am unable to reload the OS on it. I have erased the drive several times. I am unable to reinstall the OS. I have everyhting that came with it. But every time I try to load 10.5.5 from the grey (?!?!?) CD's I get an error message "Cannot install Mac OSX on this volume". Well, that's helpful. lol Yes, I've Googled the hell out of it. Someone said somewhere that the discs I should have... should be blue? My friend never got any different discs. These should be the discs that came with it. I am not an Apple guy, although I do IT for a living so I am not clueless when it comes to Apple. I support an Apple PC in my office. Would you believe the battery still holds a charge on this old thing? LOL I hate to jst throw this thing in the trash. I just cannot bring myself to do that. Any ideas besides sending me to yet another webpage to do yet another (failed) attempt and reinstalling.
