and it will not install updates from software update. I tried manually installing updates but they don't take effect because I can't restart the computer all I can do is shut it off. Same thing, no? Its been like this for like half a year but now I really want to stay up to date, especially for facetime! It says I need to install a security patch. Tried resetting PRAM Tried Booting from the disk and and running the thing that fixes ****. I forgot what its called. Help obi-wan you're my only hope.
