Hi. Life long Windows user converting to Mac. Just took delivery of a iMac i5 yesterday. I've been reading lots of posts here and on Apple iMac forum with people having issues with the last updates from Apple, e.g. SMC causing fans to go to high speed and staying there. It has me nervous to apply the all the updates Apple has available for my iMac. Just wanted to know if i should wait awhile or do you think the majority of people updated without problems. Thanks.
