My macbook wont boot Before i shut down, there was a problem with my dock not bouncing or doing anything like that. So i went to terminal and Killall dock, but it said it could not find the process. So i decided id restart to get my dock back working On start up i get the following errors CSRHIDTransitionDriver : :stop IOBluetoothHCIController : :start Idle Timer Stopped I've done a bit of googling, and ive even searched the forums, but i cant seem to find a way to repair it. Ive got back-ups so if worse comes to worse, i can erase and intall, but its a pain for me to get my disks down out of the loft, so i was hoping i could fix my problem without the disks. Ive tried to boot to safe mode, but same errors. I've reset the PRAM. I can boot to single user mode, and it says stuff that all seems normal until here: So naturally i type sh /etc/rc and it returns: I dont know what else to try to get this to work. I tried fsck -f, but that said the disk was fine. Please help!! EDIT: Its a macbook 1.83ghz core duo, with 2GB of non apple ram. Its still got its stock 60GB HD in if that matters. EDIT2: Ive also found that in single user mode my disk is read-only. Is that normal? How can I make it writeable.
