    Hey guys,
    I just picked up a macbook air revB SSD and am trying to restore the disk image to what I had on my old MBA. However, using Carbon Copy Cloner or Super Duper, after I create a bootable disk image from my old MBA and try to boot it from my new MBA, it just restarts when I select the USB HDD's icon. Does anyone have a good idea of what is going on? How can I create an exact image of my old MBA onto my new MBA, considering the fact that there's also only 1 USB port.

    Any help is appreciated, I'm getting quite frustrated over all this non-working stuff.

    Rev B and Rev A's OS builds are different due to difference in chipset architecture. ie Nvidia MCP 79M vs IA 965GMS.

    So easiest way is to stick a USB drive on the Rev A amd do a complete TM backup on it. Then use that same drive, and to a TM restore from the Rev B using Migration tool in Utilities folder of Applications. You might have to redo this as TM sometimes clocks errors on the drive (it is not the most reliable backup system I have used).

    The good side of the grass.
    I did it like the quoted post says but different. Actually did a time machine backup on ext. USB drive w. old Air. Started new Air. When startup stuff hits migration asst. and asks if you'd like to migrate data from old mac, answer yes, check all boxes for all data and choose TM backup DB. Plug TM HDD into USB port and wait a couple hours. My new Air looked exactly like my old Air.:apple::apple::apple::apple:
