How does Apple Mac set the Lost mode? We all know that iOS devices have the "Lost Mode" feature, the ability to lock devices through icloud, there is a chance to recover their lost devices, in fact, Mac also has this feature. Today, small make up to everyone to bring the "Find my Mac" function, I hope to give this function is not very understanding of the friends to provide some reference, to avoid the pitfalls of trouble, come together to see it.

First, let's say the "Find my Mac" feature is turned on and the way to set the Lost mode:

First, to turn on the "Find My Mac" feature, we can find the "Find my Mac" option in System Preferences > ICloud for Mac computers, which will require a Mac user to turn on the location feature (if the location is not turned on) when it starts. The way to turn on targeting is: System Preferences > Security and Privacy > Privacy > Location Services.

Second, when the "Find My Mac" feature is turned on, if a Mac is lost or stolen, we can do it through any computer that can be networked (Mac or Windows pc):

1. Open "Find My iphone" on ICloud or Iphone/ipad device, enter your Apple ID and password, select "All Devices" in "Find My iphone", select your MAC computer and lock it.

2. This time, the system will let you enter a PIN code. This lock code is very important, if lost, even if the MAC computer is back to use.

3. When turned on, the computer is deactivated and requires an access password.

In this previous tutorial, the gadget has introduced the firmware lock Setup method, that is, in the Boot boot section is locked, this is a motherboard lock, even if the replacement of hard disk can not be solved. ICloud lost mode in Find my Mac is essentially a direct lock in the boot section, no boot without the correct PIN, and option/command r/command option R.

And the worst thing is to turn on the ICloud lost mode and forget the PIN code, when you can only prepare the original purchase invoice and other supporting documents to prove your master identity, go to Apple for paid unlock, so do not lose the MAC computer when it is not easy to turn on Lost mode.
