I bought one of the new iMacs to replace a 2008 iMac. It won't arrive for a couple of weeks; in the meantime I have a few questions: 1) If I do a restore from backup from a Time Machine backup to transfer data to the new iMac, will older Mac apps like iDVD still work? (I know. The new one doesn't have a DVD player built in, but if I had their external DVD drive, etc. - it was the first app I thought of. ) 2) My old iMac was not encrypted. If I want to do a restore from backup, do I encrypt the new one with FileVault 2 before or after the Time Machine restore? 3) After a restore, can I continue to use the old backup drive on the new machine (and does encrypting the new one matter in this situation?). Or, related question, can I copy over the old backup data to a larger backup drive and then use the larger one normally as a backup drive to the new iMac (after having done a restore)? Thanks.
