a.k.a. macOS budget meal
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.
Intel Core i5-2540M @ 2.6GHz
8 GB DDR3 RAM
SanDisk SSD PLUS 120 GB
Intel HD Graphics 3000
Atheros AR5B95 (AR9285)
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
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)
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
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
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
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
sudo pmset -a hibernatemode 0
in the TerminalDelete /Library/Extensions/AppleBacklightInjector.kext
Reboot
