Perfect Vanilla EFI for Lenovo ThinkPad T490, ONLY For macOS Big Sur to Sequoia (Trijintosh)

[Trijal]

Here it is for macOS Big Sur to Sonoma! PLEASE READ EVERYTHING BELOW BEFORE USE!

 

CLICK ME TO DOWNLOAD OPENCORE

To download the EFI on GitHub, all you have to do is click "Source code (zip)" under the assets section and you're ready to go!

 

Everything works except for HDMI, for Wi-Fi in macOS Sequoia 15 you need to use HeliPort. On macOS Big Sur to Sonoma, it is built in to macOS. 

Also, it is reccomended that you use the YogaSMC app for the best experience out of this Lenovo laptop!

Always check back for updates in my GitHub every 3 or so days. You'll be able to see the update(s) in the GitHub commits or the releases/tags.

Furthermore, if you don't know the difference between OpenCore and OpenCore MOD; it is that the MOD version can boot into other operatings systems except for macOS without injecting the Hackintosh stuff to them.

Please donate to me on Ko-Fi if you really appreciate my work ??! Any amount would be so beneficial to me! CLICK HERE TO DONATE!

Please pin and star this topic?? @MaLd0n. It is very useful!

Update! Fixed it by removing these kexts: Vood0012C.kext, Vood0012CHID.kext and VoodooRMI.kext

Hey thanks for the EFI folder, my only two issue is: 1. Mousepad and keyboard do not work the touch screen works but thats about it, 2. I installed the system via external mouse and keyboard but sometimes when going to sleep it will completely crash and reboot anyway to fix that? I'm just the exact config and kexts from the git repo besides a generated SMBIOS

I never had these issues on my machine. It literally runs perfectly. So I am not sure why you are having these issues, even though it seems you have the same exact variant of the ThinkPad T490 as mine.

Hi Trijal,

That is, booted into Macos,the screen become purple（or pink?）,and thers are two mouse cursors,all on desketop are two copy(include taskbar on top of screen)

I didn't know why.
