No product is ever perfect, even Apple's wildly successful MacBook line. A number of vocal MacBook owners have been experiencing annoying random shutdowns, and fortunately, according to Apple, a fix is finally at hand. MacBook SMC Firmware Update 1.1 promises to fix the problem by adjusting the MacBook's internal monitoring system. Apple recommends the 417K download for all owners of MacBooks, even those units that have already gone through a repair process. You need to be running at least Mac OS X 10.4.7. And because this is a firmware update, remember to back up your data beforehand in case something goes wrong.
Enter Dashboard, Expose, or Spaces Temporarily
Hold down F9, F10, F11, or F12 (or whatever you've set for the Expose and Spaces keyboard shortcuts) for a few seconds, and then release the key to enter and leave the appropriate mode without having to press the key again. This is particularly useful for Dashboard, in which you can check the contents of a widget and then return to your work with only a single key press.
