So I'm having a problem with my macbook air install disks. I have an external DVD drive (not macbook air's superdrive) and it can read my iMac leopard cd. However when I try to read the air's dvd it doesn't work. If I put the air's install dvds into my iMac's superdrive it reads. So I'm wondering did apple mac it so that the cds would only read on a superdrive!??! Note: I had my computer formatted by the genius bar once and when they returned it my multitouch trackpad did not work and my keyboard would not illuminate. I believe they probably installed a desktop or the retail dvd on my computer. I got my trackpad working again by using the four finger hack and it got my keyboard illuminating again. Anyways, I don't think this had any effect, cause I don't remember being able to install leopard on my computer before this.
