hey lads, anyone noticed after the 10.5.7 update you run slower. my keyboard is taking time to catch up with my typing now and i have to wait a noticeable amount of time longer to load webpages. i have a Intel iMac, which has not been affected as badly, but my MacBook is really bad since the update? I have scanned for viruses and used onyx to see if that solved it. but not luck. is this a problem with just me or the update in general?
