    Im using a 3rd party USB adapter for my MBA Lion. It cost much cheaper than Apple's own. Only (USD10). Regular booting will not work for this adapter.
    Anyway, whats the danger booting up from 32bits kernel ? Or is there any ? And what does it mean ?
    I certainly do not want to harm my newly shiny MBA :apple: Thanks in adv.

    What kind of adapter is it - what's it adapting to?

    Check the manufacturer's site for an updated driver (kernel extension or "kext"). Also, if you can find out which chipset the adapter uses, you can use that info to find a 64-bit driver for it.

    Not much right now. Some 2007 MacBooks are capable of running Lion but boot into the 32-bit kernel by default. That said, the 64-bit kernel speeds up low-level system operations.


    Is it a USB ethernet cable that you are using?

    Thanks for the link. KPOM. It is a USB ethernet adapter tht im putting up to discuss.

    The title should have been - USB ethernet adapter (3rd party).
    So i guess, it is ok to use them on new MBAs mid 2011.
