I have a 2.2GHz MacBook Pro (Santa Rosa)... It has been performing like a champ for the two days I had it until last night. Right after checking software update and updating the Safari Beta app and the Security Update, now my MacBook Pro is dead slow. Is anyone else having this problem? I ran xbench and geekbench on my computer the day I got it. I noticed the performance issue after the updates last night, but was too tired to mess with it. Since, I have run both benchmark apps on my computer and am not getting even half the score I got before the updates. I did create a new user to see if maybe it was something else I may have installed, but I get the same results. GeekBench- Pre update score - 2960 Postupdate score - 1080 XBench- Pre update score - 55.15 Postupdate score - 34.77 Those are some major downgrades in performance. I can honestly say that this MacBook Pro is currently not any faster than my PowerBook G4 1.67GHz. Has anyone else seen this same thing happen after the updates?
