I don't know what's going on. My MBP(Penryn March 14th) has been very sluggish lately. I first noticed it late last week. The login screen with the apple wouldn't go through, the spinning thing(sorry for my n00bness) just kept going round and round. Held the power button to cut it off and booted it back up. Went through but then it hung on the blue screen between the apple screen and the login screen for a while. My friend told me to repair the disk permissions, I tried that but it has still done the same thing several times. I also see the beachball quite a lot. Twice this morning when waking from sleep. These were some pretty good hangs too. Everything locked up. And I had to just wait, one was for about 2 minutes the other I got frustrated and held the power button. I never max the processor. It's never been past 40% usages says iStat Pro. More than a gig of RAM is always available. I don't do anything intense. Probably the most intense thing was Time Machine backing up or was watching Friends Season 4 Disc 1 the other day on here, that's the only time something has ever been in the superdrive. Instant messaging and web surfing are my only usual activities. With mail going in the background and the occasional iTunes playing via speakers. I've had 3 Kernel Panics, 2 related to bluetooth. One I'm not sure what caused it. This is my 2nd MBP too, all my info was transferred from the first one, which had the fan buzz, if that can help identify a problem. Anyone have any ideas? Sorry for any incoherence, I wrote this on the fly.
