I just installed new RAM on my brand new 2.4 GHz Macbook..... ...man it took some effort! It took me about 45 mins to do it. Why? 2 out of the 8 screws were so tight in the case that i broke a screwdriver in the threading!!!! Luckily i had another screwdriver to do the job and somehow i managed to get the little buggers out but man i was ready to throw the thing outta the window, i was soooooo frustrated. Thank goodness i didn't mess up the screw threads or do any damage to the notebook whatsoever so in the end a job well done, but man i was thinking it wasn't gonna happen for me for a while! Anyone else come across this when fitting after market RAM???
