I cant get into my mac by starting it up regularly, only way i can get into my mac is going into safe mode. Its a mid 2011 imac with Lion preinstalled also to make it worst i cant reinstall lion since it says its damaged. Any suggestions also, im new to mac and run bootcamp half the time. Its a base model 21.5 mid 2011 imac. Tried Single User mode and V mode both are successful but boot in "Mac os Utitiites" WHich is the recovery partiiton I think it something to do with software update in lion i got last night, also 300 views and 0 replies just because im a newbie. Not into mac os but can you still help me? Won it in a youtube giveaway, hope it makes you angry enough to reply verified permissions and disk all seem to be ok. My sister tried to go into guest mode to print something on my printer.
