Yesterday I udated finally to the version and left my pc to tend to other things. When I came back and tried to boot it wouldn't log into the OS only kept restarting the computer. Now I want to know since I reinstalled the OS again, is it safe or should I wait again? I am thinking that by now it should be safe, and I have an idea that it was something else that I was updating that caused the crash! Anyone can confirm that 10.4.9 is ok?
