Lenovo-T460-OpenCore VS IntelMausi

Dual Battery (with corrected reading for average remaining capacity of both batteries)Battery SSDT patches used from this Thinkpad T460 repo (They are almost Identical Models) as I found trouble with the guide linked from Dortania. SSDT's used from this repo were SSDT-BATC, SSDT-BATT and SSDT-NTFY. You need to also create ACPI patches in your config.plist file, these patches are found in BATT and NTFY. This is not a 100% accurate reading (off by 5% or something) but it works.

https://github.com/MSzturc/Lenovo-T460-OpenCore I found and it claim that it has working working audio with headphone jack "Realtek ALC239 Audio (including headphones jack)"

https://github.com/MSzturc/Lenovo-T460-OpenCore just clone this repo and it will make your life a lot easier

Intel I219-LM Ethernet - IntelMausiEthernet

Try installing this kext: https://github.com/acidanthera/IntelMausi/releases

for worked intel ethernet require IntelMausi.kext (https://github.com/acidanthera/IntelMausi), for check internet connection in installer open terminal utility and type ping google.com or ping apple.com if packets not lost - have success internet connection.

Also, I want to know if the integrated GPU and Network will work, for the GPU if the complete VRAM will work and for the network I have seen this patch and I don't know if it works : https://github.com/acidanthera/IntelMausi - The card is an Intel I219-V

Ethernet (IntelMausi)

Hope you are using the Lates Release of IntelMausi. Have you added the required device property or bootargs?

For ethernet you would need IntelMausi kext as it is an intel chip. https://github.com/acidanthera/IntelMausi

Your board appears to have the Intel I219-V Ethernet chipset, so it should work with IntelMuasiEthernet... unless your copy of the kext is just too old? It's had a name change within the past 8 years, after all. You can find the latest version here: https://github.com/acidanthera/IntelMausi/releases
