Hi, I hope someone could help me fix this. I ran software update and got (iPhoto, itunes, Security patch) so I ran it and downloaded everything except the Intel Security Patch. So I restarted and decided to try again. Restart didn't work as it got stuck and I had to reach around and restart by holding down the power button. When it came back up, I got the white screen with the grey apple logo and the spinning clock like icon..... spinning and that is where I am stuck, left it off all night and tried it in the morning, same thing. I did try: -resetting pram (nothing happened) -restart in safe mode, holding down shift key (nothing, stuck on screen) I would try to start up from the OSX disk except I have a DVD in the machine. I am thinking it was that security update that didn't download fully that is doing this but how do I get the iMac, "unstuck"? or how do I manually eject that DVD to put in a OSX start up disk? flustered. thanks.
