4K monitor works on iGPU and eGPU #3
Comments
Thanks for confirming! I'm glad ThunderBolt works, I wasn't sure if it would work without more ACPI patches. Did you set the ThunderBolt security to legacy? I'm not sure if that one is needed. |
Yes - set to legacy - can try setting it to normal and will repot back

Thanks for checking! Not sure what the difference is between those modes. The speeds are the same so in the end doesn't really matter. Will update the readme to reflect eGPU and TB3 stuff works. |
TB3 eGPU works on mac or windows? I read in tonymac those successful NUC with eGPU hotplugging (Hacmini & NUCi8BEH) they had to flash custom firmware on the TB3 chip to make it work on Mac OS. |
It will work in both given the card is supported in macOS. For TB3 hot plug you need to patch the firmware. But devices work fine without it. Just no hot plugging. It might be possible to make hot plug work in Windows with the patch applied but that depends on what the patch changes. You can try bootcamp thunderbolt drivers from Apple for a model that has this chipset. Maybe those can make hot plug in Windows work again. |
zearp, I am having a hard time with my HDMI port, I have a flicker issue. I tried the thunderbolt fix and got a panic `panic(cpu 2 caller 0xffffff8013e4205a): "XHC2(Macmini8,1): thunderbolt power on failed 0xffffffff\n"com.apple./AppleInternal/BuildRoot/Library/Caches/com.apple.xbs/Sources/IOPCIFamily/IOPCIFamily-428.80.2/IOPCIBridge.cpp:1428 Process name corresponding to current thread: kernel_task Mac OS version: Kernel version: System uptime in nanoseconds: 509397763816 any advice? |
@chadthomas31 It looks like you patched the Thunderbolt firmware. Also don't hijack issues, create a new one and provide more information and at the very least steps for me to reproduce the issue. How else can I help? The panic you get has nothing to do with hdmi. This is the panic you get when waking up from sleep after having patched the Thunderbolt firmware. The controller isn't turn on fast enough. Please reverse the Thunderbolt firmware patch, update your EFI with the latest release and try again. If you get panics again open a new issue. |
thanks and sorry about the hack, my 1st post. But I should know better |
No worries! I hope reverting will sort the issues. The TB3 patches do work but require some user land fixes for sleep and usb functions. Patching TB3 is only viable if you don't care about sleep or usb functionality of the usb-c port and need hotplug more than anything. It would be nice to sort out but as far as functionality and stability things work best with the default config. |
Can confirm 4K monitor works on iGPU
Also 4K works on eGPU via thunderbolt 3 enclosure
