hi, i want to update my mac to 10.6.4 but the thing is that my internet connection is slow and whenever i pause the download and come back later to continue the download i receive an error message after a while and everything that i had downloaded is erased and i have to re download everything again. so if i didn't download the update and specifically this one, what would happen? i'm new to mac. so shall i wait for the next update and stop downloading this one? the download is like 600+ MB, hoped that apple send like discrete downloads like in small storage so that i can download each enhancement/update alone.
