Hello everyone, I'm glad to share my results here.
My processor is AMD R5 4600H.
Motherboard is Huawei KLVL-WXX9-PCB
The hard disk is a portable hard disk Jamboron Foresee NGFF 128GB
Wifi&Bluetooth AX200
The system I am successfully running is big sur 11.6.6 (20G624)
Basically a lot of performance is realized, for example:
Touch screen
Touchpad
Keyboard backlight adjustment
HDMI monitor output
Type-C monitor output
Sound output
Ethernet & Wifi & Bluetooth
At the same time, I also encountered three problems without ideas to solve them
1. About external monitor
1. when my external monitor is connected via HDMI, the USB port of the monitor doesn't work, and the speakers of the monitor don't work either.
2. when my external monitor is connected via Type-C, the monitor's USB port works, but the monitor's speakers still don't work.
2. Regarding the speakers that came with the laptop
1. the normal boot works, and when I connect a 3.5mm device it also works; but when I unplug the 3.5mm headphone jack, the laptop's speakers don't make sound anymore, only from the headphone jack. Don't connect the 3.5mm reboot it can be restored
3. About the boot code loading process
1. I find it very strange that every time I turn on the computer, the code loading process freezes when it reaches the CPU ID or Copyright. Since I installed MacOS on a portable disk, I unplugged the portable disk and plugged it back in, and the code continues to load then get into macOS. This confuses me! I don't know what the problem is, and sometimes it crashes completely, and I'll have to force a reboot and get into the system the same way I just did. (This is what bothers me the most, I hope a knowledgeable guru can help me look at this and see if it can be fixed)
2. Below is a picture of the problem I encountered and my EFI file.
Thank you in advance, and to anyone who has the same laptop as me, my EFI file can help you enjoy it.
