The Quadra 660AV has a new lease on life. Apple's announcement to dealers that the Quadra 660AV 8/500/CD model (M2691LL/A) is being replaced with a similar model (M2691LL/B) containing a tray-loading CD-ROM drive, effective today, suggests that the machine will be around for a while longer. (Its cousin, the Quadra 660AV model with 8 MB of memory and a 230 MB hard drive, was converted to the Apple CD300i Plus tray-loading drive a while back.) The Quadra 660AV models cost several hundred dollars less than similarly configured Power Macintosh 6100 models. [MHA]
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.
