Q: Moving files from a Time Machine backup manually vs restoring from a Time Machine backup
I have read several articles saying that contemporary Macs and OSs are built such that they clean themselves up - defragmentation, general sweeping, etc. I was told by the Genius, however, that there are many little files that are left lying around after installs, uninstalls, file making, and file deletion that will gum up the works. He recommended that I set up my computer as though it's brand new and manually transfer files over from my Time Machine backup folder on my ExtHD.
Because I couldn't find a discussion of this specific topic online, I thought I'd bring it to the community myself. Is there an advantage to setting up the computer from scratch and manually moving the files (provided I use Migration Assistant for applications)?
For background: My Mac was running slowly, and after doing some research and talking to a "Genius", I thought it would be wise to reformat my HD and restore my system. Aside from sluggish performance, I was experiencing strange symptoms - like free disk space remaining the same even after deleting huge files, permissions errors, etc. I tried doing a permissions repair (a process I'd been told to do before when experiencing issues, even though I never knew what that really did), and read that I should verify my disk as well. Disk Utility told me that I had to reboot from the repair disk to perform the necessary repairs. The repair disk Disk Utility told me that my disk had some major issues and needed to be reformatted and restored.
HOURS LATER: I am back up and running now and Disk Utility is showing the appropriate amount of free disk space.
