MACOS MOJAVE 10.14 ON THE THINKPAD X220
With the release of macOS Mojave 10.14, Apple ended support for their own notebook models with specifications comparable to the ThinkPad X220.
Apple’s transition to the Metal graphics framework involved depreciating OpenGL and OpenCL. The Intel HD Graphics 3000 found in the X220 as well as MacBook Pro and MacBook Air models proced before 2012 is not compatible with Metal.
While Mojave can run on the X220 by patching in graphics kexts from previous versions of macOS as detailed in the guides listed below, we believe the lack of native graphic support in Mojave makes this an appropriate time for us to stop creating new guides for installing macOS on the X220.
We hope you understand this decision. All of our existing guides will remain where they are and we will continue to provide support for these versions of macOS on the X220 into the foreseeable future.

GUIDES FOR MACOS MOJAVE 10.14 ON THE THINKPAD X220:

GrifterGuru’s guide on thinkpads.com
Follow these steps to perform a clean installation of macOS 10.13 High Sierra on your ThinkPad X220 or X220 Tablet with an Intel Core i3, i5 or i7 CPU.
Most macOS 10.13 High Sierra features are fully functional on the ThinkPad X220. See the Not Functioning section of the Notes and Suggestions at the bottom of this page for the latest status.
If you already have macOS 10.12 Sierra, OS X 10.11 El Capitan, or OS X 10.10 Yosemite on your X220 we recommend a clean installation of macOS 10.13 High Sierra, not an update from the existing installation.
PART 1 OF 4: ADJUST BIOS SETTINGS
Wi-Fi card recommendations:
Stock Wi-Fi cards in the X220 are not compatible with macOS
Wi-Fi cards that require no configuration whatsoever and will work automatically in macOS:
For 802.11ac + Bluetooth as well as Continuity/Handoff support, it may be possible to make the AzureWave AW-CE123H (aka Dell DW1550) card work by following the steps in the guide here. Another guide that might be helpful is available here. Note that it will not be possible to boot from our standard USB installer with this card installed; only install this card after the macOS installation is complete and the necessary modifications have been made
Various other Mini PCIe and USB Wi-Fi adapters compatible with macOS are listed here
A video showing the process to replace the Wi-Fi card can be viewed here

Touchpad, TrackPoint and Tablet Input
The <PrtSc> key toggles the touchpad on and off
The <ScrLk> and <Pause> keys adjust screen brightness as do the standard <Fn>+<Home> and <Fn>+<End> keys
The <Insert> key will eject the CD/DVD drive (attached by USB or docking station)
The <Windows> key functions as the macOS <Option> key
The <Alt> key functions as the macOS <Command> key
The <Fn> key is used as follows:
<Fn>+<F4> puts the computer to sleep
<Fn>+<ScrLk> toggles NmLk (to use the right side of the keyboard as a number pad)

Some users have reported random freezes where the system continues to run but the user interface becomes unresponsive. This problem occurs on many different platforms under High Sierra and is not specific to the X220. Only some X220 units are affected and we have not been able to reproce the problem on our test units. We believe the problem may have something to do with the graphics framework and shared system memory. Here are a few things to try if you encounter this problem:
If you have two RAM moles installed, try removing one and see if the problem still occurs. It may be that just one mole that is the source of the trouble.
If you have less than 8GB of RAM, adding additional RAM may help
Try adjusting hardware acceleration settings, if possible, for applications that are running when the freezes occur (such as Chrome)
