Hackintosh: Making macOS Security Updates in 2021

It is important to keep your computer up to date with  the latest security patches. You are just as vulnerable to attack as anyone elses PC.

This article deals only with minor (or security ) updates to macOS on a Hackintosh . If you want to switch from macOS 10.13.5 (High Sierra) to macOS 10.14.6 (Mojave), this won’t be the right way to go at all. We will only deal with minor macOS updates ( 10.14.2 to 10.14.6 ) for example.

Prerequisites

  • A Hackintosh
  • A Time Machine hard drive
  • A bootable macOS USB key (in case the update crashes and everything needs to be reinstalled)
  • Make sure your components are supported by this update

Concrete case

We will take my case as an example: I recently installed a new Hackintosh under the latest version available at the time (macOS Mojave 10.14.5 ).

Last week, Apple released a security update that addressed the loopholes. It’s best to keep your computer up to date with the latest security patches. I will always advise you to update your devices, but not immediately. Only a few days later, while waiting for other people to rub shoulders so as not to install an unstable system.

We are therefore going to install this update (macOS Mojave 10.14.6 ), since I have not seen any compatibility issues with my hardware.

Backing up your data

First of all, you will need to be sure to have your data backed up in case the update fails or crashes the system. We can then reinstall the system using our bootable USB key and restore our files and applications with Time Machine.

I therefore invite you to back up your hard drive with the Time Machine utility (either on another internal drive in your PC, or on an external hard drive).

Update

To download the update, it’s easy. Go to your system settings in the Software update tab. Download the update and install it.

Your computer will then reboot twice. In Clover, the first time select Boot Install macOS Mojave from Macintosh HD (system or disk name may differ). The update will then install, wait about ten minutes. The second time, select your usual startup disk.

If all went well, you should have installed the update, and booted into the system.

In case of problem

If the system crashes during installation (very rare, but risk 0 does not exist), and you cannot restart on macOS. Reinstall the latest version using your bootable USB key. Then, when the system is reinstalled, use your last Time Machine backup and restore it with the Migration Assistant. You should have your system up and running after that.
