    I've seen quite a few threads on here advising people to repair their disk permissions after they experience problems. Curiously, I have also seen some people who seemingly repair permissions after each update to OS X. My question is this: doesn't OS X do this on a regular schedule, behind the scenes? Is it advisable to repair permissions when large-ish updates come out, or is that total hogwash (assuming there's no real "issue" you're trying to fix)?

    Some people repair, or recommend repairing permissions for situations where it isn't appropriate. Repairing permissions only addresses very specific issues. It is not a "cure all" or a general performance enhancer, and doesn't need to be done on a regular basis. It also doesn't address permissions problems with your files or 3rd party apps.
    There are times when repairing permissions is appropriate. To do so, here are the instructions:
    If repairing permissions results in error messages, some of these messages can be ignored and should be no cause for concern.
