I seem to have corruption on my HD. Ran First Aid which showed this alert, "First Aid corruption that needs to be repaired. To repair the start up volume, run First Aid from Recovery." So how do I do this?
MacBook Pro 15", OS X 10.11
first try holding command R when you boot up to get to the recovery volume on your machine.
If that fails to load Internet recovery command option R
Boot into Recovery (Command R) and from the dropdown menu: Utilities> Disk Utility> run the First Aid on your Macintosh HD. If errors are found and repaired, run again until no errors reported.
