Lenovo ThinkPad T480 - OpenCore Configuation

⚠️⚠️⚠️ WARNING ⚠️⚠️⚠️

THIS BRANCH IS HIGHLY WIP, USABLE, BUT KEEP IT IN MIND THAT IT'S HEAVILY AMEND AND FORCE PUSH AND I WON'T TAKE RESPONSIBLE IF THIS BRANCH BREAK SOMETHING, OR EVEN WIPE YOUR HARDDISK CLEAN

⚠️ Disclaimer

This guide is only for the Lenovo ThinkPad T480. I am NOT responsible for any harm you cause to your device. This guide is provided "as-is" and all steps taken are done at your own risk.

The ACPI patches and the style of this README are from EETagent.

Thanks valnoxy for his works on hackintosh EFI t480-oc.

💻 My Hardware

These are the Hardware component I use. But this OpenCore configuation should still work with your device, even if the components are not equal.

Check the model of your WiFi & Bluetooth card. Intel cards should be compatible with itlwm (or AirportItlwm). If your card is from another manufacturer, please check if your card supports macOS. macOS Sonoma no longer supports Broadcom Wifi cards.

• DRM (Partially, but considered it broken, use unfairgva=4 if you want drm working on apple music and partially on apple TV)
• Native Color display without any external patches (color banding is quite bad here, required either EDID patching or igpu fixup)

🔄 Not tested

• WWAN, Sierra Wireless (74xx) is "HIGHLY" recommend, L850-GL is also good to considered as well Look on HeySora's ACPI for it
• TB3 hotplug, i don't have any thunderbolt support devices (2017 MBP is currently broken so i can't use TDM) (as i might plan to buy apple silicon mac mini later, i might try fixing it) i bought the mbp m1, will fix once i got it on hand
• Secure Boot, too much setup and i'm lazy to do
• ACPI method of usb mapping (since wwan and thinkpad dock path are missing, i can't properly do it without breaking sleep cycle)

🍎 Specific Features (Boardcom Only)

• Continuity (including use iDevices as camera / microphone)
• Airdrop
• Sidecar (Wired)
• Sidecar (Wireless, pre sonoma works fine, post sonoma won't works after OCLP patch)
• AirPlay (To iDevices / To Mac)
• Universal Clipboard
• Handoff
• Apple Watch Unlock (my AW S6 is currently broken...)
• Iphone mirroring (15.0+) (Require macbook with T2 chips)
