- stcredzero 14y agoIt's still slightly problematic for me. To prevent the re-activation of DMA, I have to disable the Guest account. Unfortunately, this also disables the "Find My iPhone" application. I would like to have both. Is there a way to have the Guest account, but not let people log into it when the machine is locked? EDIT: Got it. It reactivates the Guest user when you turn on the "Find My" feature, but you can deactivate Guest user afterwards.
- duskwuff 14y agoNote that this isn't necessary. If you have full disk encryption enabled, the machine will reboot (to a limited OS) when the Guest account is requested.
