iATKOS | United Kingdom

Please see the screenshot.

I followed the instructions at https://www.reddit.com/r/thinkpad/wiki/os/hackintosh/ in the section for T440/T440s. Basically:

• On Windows machine download OC tools and install Python to download the Big Sur dmg file.
• Format a 4G USB drive, copy above files as well as latest release (OC 0.8.8) for Big Sur to it.
• Disable Secure Boot in BIOS (CSM doesn't seem to matter).
• Boot from USB, the installation screen was garbled, so I opened Config.plist file on the drive, changed the "device-id" value to "hoASBA==" (base64 encoded of 86801204).
• Then the installation is successful.
• OpenCore is updated to 0.9.4 per instruction, and changed ALC ID to 28.

Many things work, and the performance is acceptable. But the following is annoying:

• No high-DPI support, so the font is super small.
• I attempted to run one-key-hidpi, it complained no monitor was found. In system preference, no font size adjustment.
• Sleep doesn't work.

I also tried to follow the instructions for Monterey but the OC installation couldn't see the image. So I gave up.
