Hi, I have T470s with JHL6240 Thunderbolt, but not showing in system report. I saw your thunderbolt is showing in System Report, how did you managed that? Did you flash with custom firmware or just using custom SSDTs? Thankyou

I have color banding issues. Is this fix which is implemented in this EFI is for specific LCD screen model or for all FHD models in T480? I’ve also tried with Skylake GPU spoofing, but it doesn’t work on Ventura, causing boot problems,

Docking Station compatibilty

Hi, this "Lenovo ThinkPad Ultra Docking Station US (40AJ0135US)" is compatible with Mac OS Ventura?

I have a t480 with your EFI, Thunderbolt port is working (it show port on system information), and dual BOOT with Windows and Ventura.

I'm curious to know if this Docking Station will work, or anyone used with Ventura?

Thanks!

System crashes after boot

Booting my existing Monterey install with this EFI boots up to the login screen succesfully, but then crashes the whole system after some seconds or if I press anything.

Only thing I modified on the config.plist is PlatformInfo > Generic > (generated smbios stuff).

1 type C port not working...

When I plug in my phone to the charging port on my t480, everything is fine it detects the phone and all but when I change it to the tb port, it just charges. Any fix? Works on macOS big sur on my machine diff efi

Installed Ventura using your EFI, everything seems to work just fine but trackpad is not working. I made sure it is not a hardware issue by testing it in windows, works just fine there.

Slepp/Wake Problem

I have a problem, when the computer goes to sleep it no longer returns to the desktop and stays on a black screen, what could be happening?

Backlight - BrightnessKeys not working on the T480 i7 8650U + MX150 variant

I'm trying to fix some problems with my Backlight - BrightnessKeys that doesn't work, I'm using the thunderbolt and is working fine, but the Intel internal graphics is not detected in some way because on my screens the integrated screen is not detected properly, I followed the dorotania guide:

https://dortania.github.io/Getting-Started-With-ACPI/Laptops/backlight-methods/manual.html

The path of my device is: _SB_.PCI0.GFX0, and looking to the SSDT-Thinkpad_T480.aml this correspond to the PNLF.

Any suggestion to what I need to look?

The T480 is 8250u+MX150 and cannot start normally when using efi, the screen is black and there is no picture, but there is a backlight display, how to solve it?

Device SMBIOS Displayed as Mac on Kaby Lake R

even though i regenerated SMBIOS, the device property is still missing.
My CPU is 8550u.
Can you write a little bit about your merged T480 SSDT?

Apple Music DRM and Bluetooth Audio

How exactly did you get Apple Music drm(lossless) working?
Can anyone guide me, is the issue related to my SMBIOS(15,2)
Bluetooth audio is not working too inside Apple Music, it altogether stops playing music.

Can you share your EFI with me?

Thunderbolt and Sleep

Thanks Pier for your pre-built, the starting on with the macOS sound it's really accurate. The EFI works incredible, in fluidity and responsiveness. I'm still adapting to this model T480.

Sadly, I'm facing some issues with Thunderbolt (not critical)

It just doesn't show up, but I'm not concerned as I don't need to plug a Thunder device.

But i had been trying to fix the sleep as you recommended, and its no being posible. Any help it would be appreciated.

About the TB I followed you guide but erased windows partition as I don't have any plans to use it.

About the sleep, as most users I need to close my notebook constantly while I'm moving around different buildings. Every time I shutdown or sleep MacOS, it thinks the system was hard-rebooted.

wifi

Thanks for sharing this EFI.
I'm using this efi on t480 i5 8250, with bcm94360ng wifi card installed. Since it should work native, I delete the wifi and bluetooth kext, but I have problem with wifi. I cant connect to new wifi without connecting lan cable first.
And i cant join to wifi that have web login portal.
Is there any solution to this? Thanks

EFI

The results of your config look great. But I can't recreate a working EFI folder from it. Can you share the full EFI folder? I miss the config.plist and kexts.

Nevermind it's in the releases

Thunderbolt 3 - NVM 23

1. BIOS assist mode was disabled (original default setting)

2. Go to Lenovo and download:
   Intel Thunderbolt Software (Version 17.x = n22ta14w.exe = latest)
   Thunderbolt Firmware Update Utility (n24th13w.exe = latest)
   Lenovo Power Management Driver (n3aku12w.exe = 1.68.30.0 i.e. an older version)

3. Turn on Flight mode to prevent Windows updating drivers

4. Uninstall Thunderbolt Software or Control Centre and go to Device Manager and uninstall Thunderbolt(TM) Controller

5. Whilst in Device Manager uninstall Lenovo PM Device

6. Restart

7. Install n22ta14w.exe and n3aku12w.exe

8. Restart

9. Go into Device Manager and check that Thunderbolt(TM) 17.4.80.94 and Lenovo PM Device 1.68.30.0.
   You can also check Thunderbolt version in the Sys Tray Thunderbolt Software (Right click) -> about

10. Plug in charger to laptop, I used the non-Thunderbolt USB-C port due to the installation instructions on the next step

11. Install n24th13w.exe which will take you through an installer (which I hadn't seen until using the older Lenovo PM Device driver). It will say something along the lines of not plugging anything into Thunderbolt

12. Finish the installer and restart

13. Check Lenovo Software in Sys Tray; NVM version 23.0

14. Now turn on Wi-Fi
