Hi, I've been having REALLY slow boot ups with my iMac recently. I own an April 2010 iMac 27 inch with intel i7 chip. When I turn on the computer, I have the white screen with the grey Apple logo that shows up. Under the logo, there is some sort of round dial that keeps on turning (looks like a bicycle gear). I would say that it takes a GOOD 5 minutes before I get my blue screen for which I wait an other 2 minutes and then finally, I can see my desktop. As I get to my desktop, I get the Beachball for a good 1-2 minutes. Recently, I noticed that there has been a lot of lag when I surf the web, even when I am ONLY using Firefox(or 1 other application for that matter). Finally, what good spyware removal software exist for the Mac and is it worth it? Thank you for taking the time to read this post. D.
