Bill Dickson <firstname.lastname@example.org> writes in regard to On The Road and CPU (TidBITS #203): CPU 2.0.1c will automatically switch to a "docked" set if it senses that a Duo is connected to a dock, and then back to the previously-used set when the machine is restarted outside the dock. Unfortunately, if the undocked set is configured to slow the Mac down to 16 MHz when the Mac is on battery power, and then you re-dock the Duo and restart, you'll find that the machine is still running at 16 MHz. You must go into the PowerBook Control Panel's options, set the speed back to normal, and restart.
Improve Apple Services with AirPort Base Stations
You can make iChat file transfers, iDisk, and Back to My Mac work better by turning on a setting with Apple AirPort base stations released starting in 2003. Launch AirPort Utility, select your base station, click Manual Setup, choose the Internet view, and click the NAT tab. Check the Enable NAT Port Mapping Protocol (NAT-PMP) box, and click Update. NAT-PMP lets your Mac OS X computer give Apple information to connect back into a network that's otherwise unreachable from the rest of the Internet. This speeds updates and makes connections work better for services run by Apple.
