how to cancel current update of iPhoto
i got a new Macbook pro for Christmas. I wasn't thinking and it told me a bunch of stuff needed to be updated. So i thought sure. One of those is iphoto. during the 3 hour download it had an error. so i had it start updating again. during that time i started reading the reviews saying the update is horrible and it causes lots of problems. so i have since paused my upload but i don't know how to cancel it. when i open up iphoto it won't read my photos from a memory card since it is currenlty being updated. I need to cancel this update unless many of you tell me the reviews are wrong.... i can pause it but i don't see anywhere to actually stop it.
MacBook Pro, OS X Mountain Lion (10.8.2)
