MacOS Monterey on ThinkPad X230

Install

Update from MacOS Big Sur

  • If you are already using previous EFI release from our repository and running MacOS Big Sur, just download one of the update from link.
  • Once downloaded the installer also download the latest EFI release (April-2K22 Update).
  • Now you have to start the installer and follow the on screen instruction and wait till it completes. It sure takes a lot of time so grab a cup of coffee.
  • Once the update is installed, don't restart your laptop. Now is the time to put the EFI release we downloaded to the EFI partition of your MacOS. To do that:

MOUNTING EFI

  • Discover the volume identifier for your EFI boot partition. Run this command:

      diskutil list

  • The output should look something like this:

      /dev/disk0
  #: TYPE                     NAME          SIZE       IDENTIFIER
  0: GUID_partition_scheme                  *251.0 GB  disk0
  1: EFI                                    209.7 MB   disk0s1
  2: Apple_HFS                Macintosh HD  250.1 GB   disk0s2
  3: Apple_Boot               Recovery HD   650.0 MB   disk0s3

  • In this case, the volume identifier of the EFI partition is disk0s1

  • Mount the volume using the command:

      sudo diskutil mount disk0s1

  • Now copy paste only the EFI folder from the release file to the EFI partition.

  • Now it is time to restart your laptop. After the restart you may see weird graphics. So follow the graphics fix section to finish.

New Installation

  • For making the usb follow dortania's guide to setup bootable MacOs Monterey Usb.(Only do the recovery Installer part and we dont need the EFI part).
  • Once you have made the bootable usb. Just Copy paste the EFI from our latest release to the root folder of the usb. Make sure you have a good internet connection (Both Ethernet and Wifi must work now. Thanks to the updated Kexts).
  • Once installations is over follow the MOUNT_EFI Section of the Update MacOs. Once Done Follow the Below Guide to Fix Graphics.

Intel HD 4000 Fix

  • So In Monterey they have dropped a lot of supports which include Intel HD 4000. Thanks to @chris1111 for the Intel HD 4000 Patch.
  • I have included the patch in the release file.

OpenCore config setup: csrutil authenticated-root disable : NVRAM > Add > boot-args -v keepsyms=1 csr-active-config > EF0F0000 SecureBootModel > Disabled PlatformInfo > MacBookPro12,1 Clover config setup: csrutil authenticated-root disable : csr-active-config > 0xFEF Once this is done boot back into MacOs Monterey

Patch Intel HD 4000

  • Open the App that comes with the release file. Intel HD 4000 app
  • Follow the on screen instruction and install the patch.
  • You may end up with error 1712. It is just fine
    • The app closes. Dont worry. Wait for a minute or two and Do step 1 and 2 again.
    • This time it will throw a different error saysing the volume is busy. Never mind. Everything is working fine.
    • Now Reboot and you will see the magic. Intel Hd 4000 will work great. If not repeat step 1 and 2 and reboot again.
