Recently I've been frustrated by having Mac OS X automatically downloading all software updates without asking. Sometimes I am on an internet connection where my downloading is limited and I don't want to be wasting the bandwidth on multiple updates that I don't need that urgently. I feel like earlier versions of OS X never started downloading the update without your permission to start the updating process. Is there anyway to ensure that the OS doesn't perform such tasks without having to resort turning off my wireless? I'm running 10.5.6 on a MacBook. Thanks in advance!
