@rustEswan hey rust, so I finally got the parts and build the PC, please note that for now I convinced my friend to wait buying GPUs and use my extra RX 580 I had lying around until prices are less.

So after installation I have 2 main issues:
1. because I used your EFI (the second one you gave to @Midphase) I by accident forgot to remove the RX 5700 XT, the RX 580 I have in this PC is by default supported so I really dont need it. So when I removed it, its still stuck with the RX 5700 XT, is there any way I can clear it out? Do I have to make an SSDT for the RX 580 to overwrite the entry ?

2. so usb wise all good, however I want to use the U32G1_12, I am not using the U32G1_34, whats the easiest way to remap the entry to use that one to get my front usb 3.0 ports to work.

Thanks so much for your help, of course worst case, I just have to plug in and out each and every port for portmapping... but the process is so long ughhh...

Not rustEswan but hopefully I can help a bit

1. You will need to disable the SSDT-GPU-RX5700XT.aml in your config.plist for your GPU to properly show as a RX 580. Although this is just cosmetic so you can adjust the 5700xt.aml to say RX 580 instead of 5700xt if you really wanted.

2. Since you’re not using the Top right internal usb header U32G_34, you can try adjusting the USBMapASUSPRIMEX299AII.kext plist and change HS03/HS04/SS03/SS04 to HS01/HS02/SS01/SS02. You’ll also need to update the location on those entries. It should be one lower than it was before.

Old Port Old Location New Port New Location
HS03 03000000 HS01 01000000
HS04 04000000 HS02 02000000
SS03 13000000 SS01 11000000
SS04 14000000 SS02 12000000

I officially have no more PCs, just a Mac Pro 7,1 and M1 MacBook Air.

It was fun while it lasted. Enjoy everyone wishing you the best in the future!

You should leave your legacy here mate, by telling us which one is more zippy in basic tasks (browsing, email, office use) between Xeon and M1 ;-) . I hope u'll jump back in here from time to time, just in case!

Congrats! I’m also in the process of finding a cheap 7,1 and repurposing my hack for other stuff :)

Xeon of course is much snappier, no comparison.

I use the M1 for more consumption and emails, browsing and slack. I tried some Photoshop stuff but it's a no go for me. I need that snappy speed so I have the desktop for that.

OpenCore 0.7.3 BASE-EFI at my github

Bootloader / Kexts:
* CpuTscSync 1.0.4
* Switched back since it is now macOS Monterey compatible. If you are still having issues, revert back to TSCAdjustReset.kext
* WhateverGreen 1.5.3
* RestrictEvents 1.0.4
* AppleALC 1.6.4
* VirtualSMC 1.2.7
* Lilu 1.5.6

This will be my last OC EFI update as I’m moving away from hacks

OpenCore 0.7.3 BASE-EFI
"The Base EFI folder contains a pre-built EFI with the OpenCanary GUI"

Is OpenCanary a real thing or just a spellchecker typo ? OpenCanopy is what it's usually called.
