macOS Mojave on the ThinkPad X220

a.k.a. macOS budget meal

Introduction (and warnings!)

This guide specifically has not been tested extensively nor is it written to be an exhaustive guide for installing macOS Mojave. This works on my personal X220. YMMV.

A more complete guide can be found at John McDonnell's page dedicated to installing macOS High Sierra on the X220. Huge props to him for supporting the X220 all these years.

Also, a lot of things don't work (at least not without additional configuration): iMessage, FaceTime, Continuity, Handoff, Metal, among others.

Versions tested and used

macOS Mojave 10.14.6
macOS Mojave Patcher 1.3.3 (download)
Clover Configurator 5.4.5.0 (download)

My X220's specs

Intel Core i5-2540M @ 2.6GHz
8 GB DDR3 RAM
SanDisk SSD PLUS 120 GB
Intel HD Graphics 3000
Atheros AR5B95 (AR9285)

Installing macOS Mojave

What you'll need:

A computer running macOS
A >=16GB USB flash drive
Install macOS Mojave.app (10.14.6)
macOS Mojave Patcher 1.3.3 (download)
Clover Configurator 5.4.5.0 (download)
A copy of this repository

Prepare the patched macOS Mojave installer (detailed guide)

Create the patched installer

Launch the macOS Mojave Patcher
Point the app to your Install macOS Mojave.app
Set the destination drive to your USB flash drive
Copy over Clover Configurator to the flash drive (in case your X220 won't natively have networking hardware configured after a fresh install)

Prepare the EFI partition

Mount the USB flash drive's EFI partition with Clover Configurator
Copy over the EFI folder from this repository to the EFI partition
Ensure that the folder structure is correct. For example, the path to the CLOVER folder should be /Volumes/EFI/EFI/CLOVER

Install macOS Mojave

Go through the normal install process (Erase the disk with Disk Utility, install, and wait until it finishes)
When the machine reboots, instead of booting from the internal drive, boot back into the installer USB flash drive
On the menu bar, go to Utilities > macOS Post Install
Choose MacBookPro8,1
Set the target volume to your internal drive
Hit Patch
When the patch finishes, make sure to select Force Cache Rebuild and Reboot
You should be able to boot into macOS Mojave through your USB installer's Clover EFI

Post-install

Configure internal drive's EFI partition

Mount your internal hard drive's EFI partition with Clover Configurator
Copy over the EFI folder from the mojave directory in this repository
Include other kexts you might need under /Volumes/EFI/EFI/CLOVER/kexts/Other (note to self: you probably want to install your AR5B95 kexts under other-kexts/ar5b95-mojave here)
Run sudo spctl --master-disable to allow apps from unidentified developers
Run /Volumes/EFI/EFI/CLOVER/kexts/_kext-install.command

Optimize CPU power management (detailed guide)

Mount your internal hard drive's EFI partition with Clover Configurator
Run scripts/ssdtprgen/ssdtPRGen.sh in this repository
Answer N to all questions
Copy the generated SSDT.aml from ~/Library/ssdtPRGen to /Volumes/EFI/EFI/CLOVER/ACPI/patched
Reboot

Change hibernatemode for better sleep defaults (detailed guide)
