This may or may not be a dumb question. Sorry folks. I recently did a software update, and like a good Mac user, I repair my disk permissions after I do a major update or install software where an installer program is used. I updated my computer, it restarted. Fine. I repaired permissions. Great. I verified my disk permissions. I don't even know what this means, but fine. I verify my disk.....First Aid Failed. A little message popped up that said. The underlying message in the main Disk Utility Window read: I'm backing up as we speaking, but does this mean my MacBook HD is a walking time bomb? Mind you, S.M.A.R.T Status says "Verified." Any help would be appreciated.
