@dangthaison91 may be you could try this minimal installer EFI with a new installer USB according to this installer-guide. Also there seems to be another version of SSDT-CPUR for Ryzen 9 CPUs. May be you could try that as well..

Thanks @alex-k , compiled new CPUR for Ryzen 3950X work perfectly. I can boot into pre-installed Mac OS with the previous Mainboard. This should be mentioned in B550 announcement topic.

@leesurone I'm glad to know, this also worked for your motherboard. In my case, freezes were sporadic and very seldom when I left default auto settings for ESPI and I2C. Sometimes system could work stable like for a whole day and sometimes a freeze would occur just after a few minutes of use.. Should you experience a similar behavior, you know what could help..

minor update:

• bluetooth via Asus USB-BT400 (worked oob)
• added BIOS settings for thunderbolt
• benchmark results for Logic Pro X benchmark project: 136 tracks @ 64 samples / 48 kHz

minor update:

• update to Catalina 10.15.7 went without any problems

@Geph0rce it must be in BIOS (advanced mode) under Settings -> AMD CBS -> FCH Common Options

thanks a lot, man

On this board sleep seems to be working fine with SSDT-SBUS-MCHC.
Yes, I left PTXH controller untouched, as it was working well without any mapping (at least for my usb devices). All PTXH ports were also indicated correctly in the Hackintool / IORegistryExplorer.

Hi alex-k
I read your information so well.
It was very helpful. Thank you.
I have a problem now, but I can't solve it.
You say PTXH ports are automatically activated.
The usb2.0 port is not automatically activated for me.
It is estimated that the usb2.0 port is connected to the hub.
It should come out on one channel each from Hackin Tool, but it's not working.
Can we fix this?
And can I see your Hackintool / IORegistryExplorer screen?

@mind hi, yes, PTXH ports are recognized by the system and working correctly without any patches. I'm also using a hub and all usb2.0 as well as usb3.0 ports are activated properly. Do you have exactly the same motherboard model? Here is a screenshot of my Hackintool / IORegistryExplorer for PTXH:

Hi alex-k
Thank you so much for answering.
The motherboard model name is
This is Gigabyte B550M Aorus Pro.
Your mainboard is a reduced version.
I am using the same chipset, so I think it is more than 90% the same.
I have 4 USB2.0 ports, but all 4 ports are recognized as hubs on the PO14 channel, so I can't solve it.
Thank you so much for the screenshot.
