Apple’s new Mac Pro relies completely on external ports for expansion, with six Thunderbolt ports, four USB 3.0 ports, one HDMI port, and two gigabit Ethernet ports. The folks at Macworld Lab put the Mac Pro’s expandability to the test, connecting 36 drives with a combined 100.63 TB of storage capacity, as well as a number of other devices. Even then, the combined devices together drew only 865 watts — less than a common hairdryer. follow link
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.
