If you think your recent Mac laptop has decided to slack off, an update released at the end of 2007 might be the solution. For Intel-based laptop owners, the fixes a problem wherein the keyboard occasionally stops responding for a minute or longer. (I've wondered what that was all about!) This update requires that the Mac OS X 10.5.1 update be installed first. (No word on whether the problem can affect 10.4 users.) The update is less than 1 MB and can be downloaded from Software Update or the Apple Web site.
