If you’re waiting for your new MacBook Air to show up, there are a few notes from Apple that may interest you before it arrives. All of the notes, including one about older base stations, outline potential issues and fixes with the MacBook Air.

The MacBook Air is compatible with the 802.11n wireless networking standard and uses a wireless network to access remote discs and install software. However, some older base stations using the draft specification may implement what Apple calls a “wide” channel in the 2.4GHz range that could interfere with the MacBook Air, which conforms to more recent draft specifications.

If this happens to you, Apple recommends changing your older base station to use the 5GHz channels or upgrade your base station to a newer model.

Another potential problem is jumpy or jerky video when using the MacBook Air’s built-in camera. This problem affects the MacBook Air, QuickTime Player Pro and iMovie and can easily be fixed by installing QuickTime 7.4.

Be aware that QuickTime 7.4 has been isolated as the cause of problems with Adobe After Effects and Premiere Pro.

If you are using your MacBook Air for prolonged periods of time and find the computer becoming sluggish, the MacBook Air may be attempting to protect itself from overheating by shutting down one core of the CPU.

Apple says that in extreme conditions, the MacBook Air may also reduce the clock rate of the remaining core. The company’s recommendation is to move the computer to a cooler area or use a notebook cooling pad to dissipate the heat.

The last issue outlined by Apple is one that many iPhone owners have dealt with — the headphone jack. Some 3.5mm headphone jacks do not fit securely in the MacBook Air’s port, resulting in poor audio quality. To fix this, you need an adapter to extend the port.
