Built-in camera may produce jumpy video
        Issue or symptom
When using the built-in camera on the MacBook Air, you may see jumpy or
jerky video.
The issue may occur when using the PhotoBooth application as well as
when using the account picture setup screen (when setting up the
computer for the first time in Mac Buddy or when editing your account
picture in System Preferences). The iChat application should not exhibit
this symptom and should operate as expected.
        Products affected
        ?       MacBook Air
        ?       QuickTime Player Pro
        ?       iMovie
        Solution
        To address this issue, download and install the QuickTime 7.4.

3D graphics applications less responsive when CPU has been in heavy use
for prolonged period
        Issue or symptom
3D graphics applications may be less responsive, or exhibit slow or
'sluggish' performance, when the CPU has been in heavy use for prolonged
periods of time or in an extremely hot environment for a period of time.
This may happen if your MacBook Air is attempting to protect itself from
overheating by shutting down one core of your CPU. In extreme
conditions, the MacBook Air may also reduce the clock rate of the
remaining core. Either protective measure may cause the application,
especially 3D graphics applications, to be less responsive.
        Products affected
        ?       MacBook Air
        Solution
To improve responsiveness in warm conditions, move your computer to a
cooler area, or consider using a laptop cooling pad to dissipate the
heat.

Optimizing AirPort performance while using Bluetooth
        Issue or symptom
When connected to a wireless network using AirPort and using multiple
Bluetooth devices, your AirPort may have a slightly slower transfer
rate.
        Products affected
        ?       MacBook Air
        Solution
To improve MacBook Air's Airport connectivity and signal performance
when using multiple Bluetooth devices, try the following:
        1.      Connect to a 5 GHz 802.11 wireless network instead of a
2.4 GHz 802.11 wireless network.
        2.      If using an AirPort base station, use the AirPort Admin
Utility to select a different channel. If using a third-party wireless
network, consult the documentation that came with the router device to
determine how to change the channel.
        3.      If using an AirPort base station, try optimizing the
reception.
        4.      Check for potential sources of AirPort and wireless
network interference.
        5.      If connecting to a third-party wireless network, check
to see if it's using a proprietary speed-enhancement option.
        6.      Temporarily power off secondary (or multiple) connected
Bluetooth devices.
        7.      In very crowded 2.4 GHz 802.11 wireless areas, or areas
that exhibit very weak signal strength, turning Bluetooth off
temporarily (using the menu bar icon) may improve wireless performance.
