The forecast for the next seven days: rain.

The forecast for the next seven days: rain.

Within the first week of release I have been running OS 10.6 on my MacBook Pro and all was well.

Recently I noticed that I have been running on the integrated graphics card since moving to Seattle, this explained why it felt as if the system was sluggish. Once I switched over to the dedicated graphics card (NVidia GeForce 9600M GT) everything started moving faster. Almost everything.

Once an hour, once every twenty minutes or once every day the system would hang. For twenty seconds the system was not responsive, I could get in maybe two clicks before everything stopped. It was not lag as keystroked and mouseclicks made during this hang time were not registered in any way. The system just stopped. I have read about this on forums with one solution being to downgrade the EFI firmware from 1.7 to 1.6. This sounds risky since my computer shipped with 1.7 so 1.6 might just fail completely.

Sunday I decided to try to fix it on my own. First thing I did was verify the main hard drive and repair permissions. No major problems with either of these. Next was a hardware test off the original install discs, passed with no issues. The last hardware maneuver was to rest the PRAM. Back into running the OS I checked all the third party programs that run in the background. I found out that the major three that I use were out of date and lacking 10.6 support (Caffeine, Quicksilver and Keyremap4Macbook).

After these steps I have not had a hang in over a day. Usually I get a couple with Matlab running and I had it open most of the day. Hopefully this is a working solution else I will need to wait until 10.6.2 is released in the next month or so.
