i want to upgrade to mavericks but my disk needs to be repaired with a disk. so i did a disk utility verify and it told me i needed to repair it with another disk.
but my mac was preinstalled with snowleopard and the disk that came with it is mac 10.5 so when i tried to do a start up with the disk it just freezes the moment i click on the start up disk. (did this by trying holding down option/alt button since holding down the C button just locks my screen to the gray screen)
and 'repair disk' is greyed out. and i read somewhere that you can't boot with a disk that is lower than what the mac is.
what can i do?
in case anyone asks for my model:
it is a macbook pro early 2011 model with preinstalled snowleopard
