Not all Mac users think about protecting their computer and data stored on it.
The operating system and Apple hardware already have everything you need out of the box, you just need to spend a little time setting up and activating the protection.
We suggest not postponing it and right now protect your Mac from theft and loss of information.
Disable login without password
First you need to make sure that on a Mac, only accounts with complex access passwords are used without stupid and obvious prompts.
Of course, the guest account cannot be used in this case, teach all Mac users to enter a password when they log into the system.
1. Go on the way System Settings – Users and Groups .
2. Remove the protection to make changes.
3. In the Login Options section, disable Auto Login .
4. Disable guest account.
The data stored on the Mac has basic banal protection. From an advanced hacker will not save, but annoying colleagues, children or a computer thief will never get data from the computer.
Encrypt Mac data
Now we make security more complicated and enable data encryption.
1. Go to the System Settings – Protection and Security – FileVault .
2. Remove the protection to make changes.
3. Activate the option and follow the instructions of the setup wizard.
4. Choose an emergency method to reset the encryption password: using a key or through an iCloud account.
In the first case, you will have to store this key securely, and in the second case you will have to attend to account security and enable two-factor authentication.
Attention! If you lose the FileVault encryption key or access your iCloud account, you will not be able to recover the password to access the data on the encrypted disk.
If you have multiple accounts on your MacBook, you will need to enter its password to enable encryption on each one. Otherwise, you can encrypt data only for the current account.
This protection prevents even a technically advanced user or hacker from gaining access to data stored on a MacBook drive.
Protect your Mac from reinstalling the system
Yes, and this is possible.
In order for the laptop in the event of theft to turn into a set of spare parts only, care should be taken to protect the EFI section.
The so-called firmware password prevents the Mac from booting from any drive other than the one chosen as the boot disk. In addition, without entering the password, it will not be possible to start the computer in most of the service and special modes .
1. Restart the Mac and hold down the keyboard shortcut Command (⌘) + R during startup to boot into system recovery mode.
2. After starting the recovery system in the menu bar, select Utilities – Firmware Password Utility (or Safe Run Utility ).
3. Click Enable firmware password and specify the new password.
4. Close the utility and restart the Mac.
Attention! This password cannot be reset using keys or iCloud accounts. It is better to create a reminder about this password in any safe place.
When you start your Mac normally, no password will be required, but when you try to reinstall or restore the system, boot into service mode, etc. You will need to enter the installed code.
Without it, and the password from the Mac user account turns into a useless piece of hardware. You can only sell on organs and then not all.
Password reset can be done at authorized Apple service centers if you have documents proving your computer ownership.
Basement SCs, depending on the Mac model, may try to make a makeshift reset of the firmware password by manipulating removable RAM or soldering chips on the motherboard.
Most of these password reset methods work only on older Macs.
We leave the chance to return the Mac after the theft
In order not to bathe with the sale of computer parts, it is easier to quickly return the Mac to the owner under the guise of a respectable person and get an award.
The only trouble is that finding out the owner’s contacts will be problematic.
There is a way to leave a message with information directly on the macOS password entry screen.
With the help of a single terminal command, you can write an entire call to a person who has found or abducted a Mac.
Do not forget to specify phone numbers or email and remind you that we are ready to pay a fee for returning the computer to the host.
Modern Mac computers have several options for protection that should not be neglected.
1. Turn on passwords for all accounts on the Mac and disable the guest account.
2. Enable FileVault encryption to protect all data on the computer.
3. Turn on the firmware password to protect the system from reinstallation.
4. We leave a reminder with your contact information.
Such a Mac will not be of great value to the thief, it may well be returned for a fee.
