Sorry if this is in the wrong forum, but I have a question about gatekeeper and I can't find anything related to this specific problem. A friend of mine is having trouble allowing apps from anywhere. Under security and privacy they allowed applications to be installed from anywhere, but for some reason the setting reverted back to only allow apps from identified developers and the app store. Now when they go to security preferences the gatekeeper preferences remain grayed out. They are the administrator of the computer and they've unlocked the lock in the lower left corner of the window so the options shouldn't be grayed out. I'm not sure what to do at this point. Is there another setting that I'm missing?
