I have a macbook 2.4GHz with 2gb of RAM. I recently installed sponge with the refrence of the Apple blog. I went to log on to my brothers account on my laptop and i got the orgnial welcome screen in all the different languages. THIS HAS HAPPENED BEFORE but it was fixed when i did a archieve and install. Unfortuantely it didnt work this time it will not let me do an install from disk nor do a hardware check. At the present time its off the charger and the battery is out. I need my laptop back ASAP for school purposes. Any ideas would be nice becuase i called apple and im out of my telephone support and i cant afford the apple care or the call.
