My old G5 has finally given up the ghost after being in a bad way for a while. For some time now if I shut it down I had to leave it for a few hours before it would start up again. Everything is backed up on an external hard drive via Time Machine. If I replace it with a newer G5 (would like a newer machine altogether but can't afford it) and plug the external drive in would I be able to load all my work and applications onto the new one and use everything the same? Thanks in advance for any help.
