I moved to software update and tried to update my mac to 10.5.7 but it gave me a message to restart directly without any type of loading or thing like that! After 5% of loading, it suddenly paused...then I quit it with keyboard shortcut! Then it restarts without installation... I tried it 2 times but the same thing happen so what to do? Please help... I will be back in a few days with a new threat! Regards From M paul!
