Well, excited like everyone else when the release came out.. I downloaded the ~400mb update file and press install. my macbook then restart and went into the leopard galaxy screen with a loading wheel in the middle spinning. i left it installing and went to work, then 10hours later(back from work) i found out that it's still spinning in the leopard galaxy screen. so i manually shutdown and turn it on again. i found that it's already 10.5.7 when it's back on. is it fully installed?? is there a way to check? any advise? thanks..
