    I assume this means launch disk utility, copy the iso to usb, boot via option/alt key.

    Particularly interested in whether anyone has upgraded yet? Currently on a stable 309. Is it easy/possible to downgrade if problems occur? Thanks

    I don't think rolling back firmware is a problem, as long as you still have the previous firmware update disc.
