Hello, kinda new to the forum. Just got my back book over the christmas and im VERY happy with it. So the problem started yesterday, after i recieved the email from apple saying that mac app store is open! I ran system upgrade right away to try out the new mac app store. So with the system update, there are also some updates about aperture, and also it said something about the Mac Firmware Update. (not too sure if this was relevant) Anyways. after the update, my start up time have increased dramatically. It used to be instant start up to the login screen, but now it takes atleast 50sec-1min to load the login screen. I dont do much on this comp, just some documents, WoW, and aperture (about 50 pictures stored). I tried running the VRAM and the NRAM reset thing. But still didnt help. Anyone have any thoughts?
