Mackbook Air 13 Inch

What Works:

Normal wireless function

What Doesn't

Untested:
Sound (not a high priority for me)

The Macbook air 11 inch uses roughly the same hardware as the 13 inch. I would be highly surprised if it acted differently, But I would love to hear about it in this thread.

Installation:
To boot I used rEFIt (hxxp://refit.sourceforge.net/) then used a standard external cd drive. Mac's super drive is probably unnecessary. Usb flash drives may also work, but aren't expressly supported.

I would advise using a tool other then parted or gparted to partition your drive if you plan on dual (or triple booting) with OSX. OSX uses a hybrid gpt/mbr partitioning scheme that backtrack's parted currently does not support, and sometimes will erase the mbr portion of the partition table. I haven't been able to get it to consistantly do this, so your milage may vary.

The other option would be to use gptsync to sync the gpt/mbr tables when you are done. This utility will do it. (hxxp://www.insanelymac.com/forum/index.php?showtopic=177505)

For more information on the gpt/mbr scheme I would read up here. (hxxp://www.rodsbooks.com/gdisk/hybrid.html)

Other then that it's a standard affair. use "apt-get install nvidia-driver" to fix video.

Trackpad:
The trackpad requires the bcm5974 driver that I currently can't get to compile. I'm not done with this yet, I'll revisit with a fix or at the very least an error log. Git repository is here: (hxxp://bitmath.org/git/bcm5974-dkms.git). Without the trackpad driver there is NO right clicking.

Not sure what kind of SD or uSD cards you have laying around, but wouldn't you want to boot this OS from a a USB SD drive/card? I have been doing some research on this topic the past two nights, and it definitely seem doable, but I am not sure if the stock BT4R2 kernel has EFI support enabled.

Anyways, personally I do not want to mess around with optical media, and that is why I have spent time researching booting a Linux Live CD or a persistent install from a USB SD drive. So far I can get grub to load, but that is it. If I get this working I will post a reply.

I have the 11.6" Macbook Air and the video did not work out of the box, it's running at 800x600. Was this the case for you as well?
