Question: Upgrade to Sierra MacMini GRaid setup
I am trying to upgrade my MacMini and ran into a problem. Apparently, it is set up as a Graid for part of the space, and the BootDisk doesn't have enough room. So now what? Is it best to visit the Genius Bar and let them help, or is there something I might be able to do myself? It has been updated to El Capitan.
