Speed Doubler 8.1 Coming in March -- Connectix has posted a Speed Doubler 8.1 FAQ that explains why Speed Doubler 8.0 and 8.0.1 don't work with Mac OS 8.1 and claims that a free update will be available in March. In short, the differences between Mac OS 8.0 and 8.1 are sufficiently great that Connectix designed Speed Doubler to disable any of its components that could cause conflicts under Mac OS 8.1. [ACE]
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.
