Sharing Discs with Remote Disc

You can enable DVD or CD sharing on a networked Mac or Windows computer using the Remote Disc feature, allowing the MacBook Air to share the discs you insert into the optical disc drive of the other computer. Some discs, such as DVD movies and game discs, may be copy-protected and therefore unusable through Remote Disc. Remote Disc works over wireless and wired networks using the Apple USB Ethernet Adapter. Note Make sure you first install the Remote Disc software on the Mac or Windows computer...

Software Sluggish Due to Excessive Warmth

Software (especially video games or other graphics-intensive software) may operate sluggishly when the MacBook Air is very warm. This is expected behavior. MacBook Air uses built-in graphics circuitry to provide video output to the built-in and or external displays. The operating system automatically reduces the processor speed if the computer starts to get too hot. This will correspondingly reduce the graphics performance of all running applications. Refer to Knowledge Base article 307297...

Mac Book Air Firmware Updates

Firmware is software that is written into memory circuits, such as flash memory, that can retain software code indefinitely, even when power is not available to the hardware. Firmware on Intel Mac computers is designed to be updated if necessary through a software update. EFI and SMC firmware is stored on the MacBook Air logic board. EFI firmware updates address the Boot ROM, and SMC updates address the System Management Controller firmware. The SMC manages fans and other environmental...

Resetting the System Management Controller SMC

The System Management Controller is an integrated circuit (computer chip) that is on the logic board. As the name implies, it is responsible for power management of the computer. It controls backlighting, hard drive spin down, sleep and wake, some charging aspects, trackpad control, and some input output as it relates to the computer sleeping. Over time, the settings in the System Management Controller may become unusable, which can result in operational anomalies with the computer. Examples...
