Can confirm. Same issue with DP over USB-C. Can only go up to 1440p with UHD620.

Are you using the patched driver from my repo? If you find it not working, then it does not work.

@philberlin Great work! Author of the "linusyang92/macOS-ThinkPad-T480s" repo here. I do not have a TB3 device so I couldn't thoroughly test if "THBT.dsl" works (it should work with Type-C devices though which I could test). I actually followed the TB3.aml to construct the file. The whole...

@GridH Yes. The latest kext by Rehabman adds kernel flags to delay enabling the driver. Please check the README.md of BrcmPatchRAM: https://github.com/RehabMan/OS-X-BrcmPatchRAM My current setting is here, which works perfectly...

Nope. T480/T480s uses PS/2 ports but not I2C for Elan trackpad. You can only use the VoodooPS2 kext or another closed source Elan driver.

@disrupt Check out my T480s' guide. I patched out Elan (PS/2) touchpad kext for multi-touch support: https://github.com/linusyang92/macOS-ThinkPad-T480s You can grab the kext here: https://github.com/linusyang92/macOS-ThinkPad-T480s/tree/master/EFI/CLOVER/kexts/Other/ApplePS2SmartTouchPad.kext...

That's correct. Some laptop may show the correct information in Windows, while others might not [1]. An alternative method is to run "setup_var" in EFI console to get the value, which should be more precise IMO. [1]...

I have met a different issue with HD520. My laptop's BIOS has 128MB DVMT pre-allocated memory. The graphics driver is successfully loaded in 10.12 with injected ig-platform-id 0x19160000. But the left top corner (upon the apple logo of menubar) of the desktop constantly blinks. I tried to set...

Edit: duplicated post, sorry...

Many thanks for the reply! However, after editing the SSDT, the bluetooth still fails after sleeping, with 0705 version of BrcmPatchRAM2. Ioreg, related log and SSDT file are attached as follows. Really appreciated if you could have a look again. Edit: by the way, all tests start from cold...

Um.. Let me explain. I first used a USB 2.0 device to plug in and out three USB ports one by one. The result was saved as "usb2.ioreg". You can find records under HS01 to HS03. After this, I didn't close ioreg app and continued to use a USB 3.0 stick to repeat the previous step. The result was...

My bad... Try this file again please. Thanks!

Ah, sorry. I thought just full USB port information was enough. Now I use a USB 2 device (mouse transmitter) and a USB 3 stick to test all 3 USB 3.0 ports of the laptop. The ioreg files are attached below. Thanks!

I got it. Here is the ioreg with all USB ports enabled, aka without SSDT injection and with port limit patch (15 -> 30). Thanks!

You mean removing the SSDT patch for USBInjectAll and enabling all USB ports?

Same issue here with BCM94352Z (Dell DW1560). After waking up, there are two BCM20702A0 entries shown in ioreg(XHC)/system info(USB). My situation is similar to OP -- working sleep (_OSI patched), native power management (ssdtPRGen) and correct configuration of USB ports (USBInjectAll w/ SSDT)...
