Let us assume: - I have a Macbook Air, 1/8/SSD + Superdrive. - The Time Machine backup is b0rked. - The Superduper backup is a 23Gb .sparseimage on an external USB drive. It does not seem to be b0rked, but of course it is not bootable. - Remote Disc doesn't seem to like to work as things stand at the moment, and I've tried quite a bit. It used to work, but it's had firmware updates, etc since then and the Air is working on a fresh from-DVD's reinstall. What would you recommend?
