Hey, all. I have an i5 iMac, and I am very pleased with it. However, for the last two or three days the Internet has been stupendously slow. On my netbook upstairs (hardlined in) the Internet is as fast as it should be from my cable modem. A couple of days ago, I seem to remember my computer updating as I went to shut it down--I installed the updates without really checking what they were. Three questions: How can I navigate to my history to figure out what the updates were? How can I undo any updates that have adversely affected my computer? And, would software updates have that drastic of an effect on Internet speed? As always, thanks.
