Hi, I followed your brilliant work on my own Lenovo T480s, and with great success.
I now have 6 different OS defined in my GRUB loader.

How ever - about a month a go I did the mistake to boot the Big Sur - and forgot to turn off upgrade - so the macOS 11.4 broke the installation.

Do you have any plans on upgrading this guide to include macOS 11.4?
Or do you maybe have a hint (besides not letting macOS upgrade)?

Doesn't go to sleep mode when closing the laptop.

Excuse me, can your efi adjust the speed of the fan? If not, do you have the corresponding ideas to refer to? thanks

EFI not working with big sur 11.5.2. i updated opencore and kext but menu not show installer pick up

ThinkPad assistant is not supported
https://github.com/MSzturc/ThinkpadAssistant

Can the camera be used? The readme file is not written, is it not working?

OpenCore is not working as boot option. I get "Faild to load configuration"
I need to go to Boot Menu (F12), boot from SSD - then I get OC boot option and can start Mac OS X

The backlight not working, if you know the issue pr the repo of replay here.

there are some patches inside your ACPI folder，eg.SSDT-TB-DSB0.aml
SSDT-TB-DSB1.aml
SSDT-TB-DSB2-XHC2.aml
SSDT-TB-DSB2.aml
SSDT-TB-DSB3.aml
SSDT-TB-DSB4.aml
SSDT-TB-DSB5.aml
SSDT-TB-DSB6.aml
SSDT-TB3.aml
which is about Thunderbolt 3，and other drivers is required？

hey, my laptop is a T480s (20L7001SRT) with 24 gigs of ram and intel 660p ssd

is there anything else i can provide to help you help me?

@m4salah Does the battery charging limit working? I have T480s i5-8350u with Ventura 13.6.6 and the battery charging liimit is not working, even already set to 80% it's still charging beyond 80% all the time.

Previously on Windows through the Lenovo Vantage already set the threshold to 80% as well

The brightness is adjustable, but the minimum brightness is too bright

Hey there!

Just curious... are the function keys working on your machine? I have been playing around with this the last few days, mostly by debugging EC-Queries (_Q), and I see that you have some of those overrides as well, in:

• SSDT-Keyboard-X1C6.aml
• SSDT-T480-KBRD.aml
• SSDT-KBD.aml

But your SSDT-Keyboard.aml contains PS2 keycode-remaps, probably read and processed by VoodooPS2. Since you literally do not have a single byte search/replace active in your config, I do not think that the three SSDTs containing EC-Queries are of any use to you, those methods will not override anything. Or am I wrong here?

My trackpad and trackpoint always went wrong at sometimes with your EFI, it happens randomly and can be restored by rebooting.

Thanks for the share of your EFI, it saves a lot of time!

when i am booting i am having elan device error please help me
