A number of users have reported difficulties with their laptops after downloading and installing the MacBook 13″ Firmware Update 1.1.
Problems have ranged from increased fan noise to increased operating temperatures to problems recognizing certain devices that had been seen before.
The firmware update, which was released yesterday, focused on fixing problems with the MacBook’s temperature sensors and random shutdowns.
In some cases, downloading and reinstalling the most recent Mac OS X combo updater (for both the Intel and PowerPC hardware architectures) can resolve these issues. In other cases, utilities such as Cocktail or Tiger Cache Cleaner can help clear the system cache and resolve these issues.
In cases where the user is having significant problems, a firmware downgrade disc can be created, although this is applicable only to situation where the firmware update failed during installation. For instructions as to how to create the firmware downgrade disc, click here.
