Apple has issued EFI Firmware Update 2.6 for the MacBook Air models that were released in June 2012. The update resolves a color issue with connected HDMI displays, a bug that caused the system to freeze if a Thunderbolt device was unplugged while in standby mode, and a problem with properly booting Windows using Boot Camp. It requires OS X 10.8.2 Mountain Lion. As always with firmware updates, we recommend relying on the App Store to ensure you get the firmware update for your specific model and being careful not to interrupt the update process.

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.
