I know this is probably all over the forum but I'm a noob with regards to Mac (been PC) and trying to figure something out. I just had a new HD installed in the imac. Original died. I had a backup of the HD on Time Machine. Actually, I have several backups on there. I wanted to restore the latest backup but unsure how to do it. Apple store provided the imac with the new HD, and I did not do Setup Assistant on first boot up. Now when I go to Migration Assistant, I'm confused on whether to replace, create new account and replace, etc. Is there a simple step by step to restore the complete backup and have it set back to the original user account? Reading this sounds confusing already - hope someone knows exactly what I'm trying to do. Thanks in advance.
