Intel Wi-Fi

Drive A：

• AirportItlwm.kext。
• To add AirPortitlWM. kext to your project, check it based on your system version, default to Big Sur.
• Separate airdrops are not available. Using AirPortitlWM. kext can cause trackpad and Bluetooth problems.
• The Intel Wi-Fi issue is not discussed because the driver is unstable.
• reference: https://github.com/OpenIntelWireless/itlwm

Drive B：

• AirPortOpenBSD.kext
• Airdrop, relay, and continuity are not available. Using AirportOpenBSD. Kext will not cause trackpad and Bluetooth issues.
• Interested friends can download their own try.
• reference: https://github.com/a565109863/AirPortOpenBSD

About the docking

• Use of docking can cause sleep problems, the solution is to add SSDT-IGBE patch to config.plist->ACPI.
• Flap mode cannot be used with SSDT-IGBE patch.
• The docking station is perfectly adapted, but some testing is needed.

ThinkPad Assistant

• Copy the ThinkpadAssistant into the Application folder.
• Start ThinkpadAssistant and check "Start when logged in" in the menu bar.
