Asus X299 - Catalina Support

Hey guys, did any of you had any luck with MacPro7,1 and serial validation? So far every single one I did comes as invalid.

I used an invalid one, and it works flawlessly! iMessage included.

Invalid is what you want.

If it's valid, it means it's on a real Mac and you might get iMessages from another person and have issues with iCloud.

Why the 2015 iMac SMBIOS?

Do you have SSDT-EC.aml installed in your Clover > ACPI > Patched directory? It's required to boot Catalina.

I boot without that SSDT. What does it do?

I believe the AppleACPIEC.kext looks for/depends on the embedded controller being named "EC" but most boards don't name their embedded controller as such, so the boot process fails. Adding this SSDT file creates a face EC device on desktops.

Hello friends, how are you?
Meet 50 shades of grey (pictured)(0 rgb)

This is my old x99 i7 6950x based computer
But rebuilt with RX 5700 XT video card

The question, to save time
Do I need to go back to @kgp original x99 guide

Or is our method here at x299 a good enough job?

Good question I'm also interested .
I think differences between config.plist are mandatory and minors

 

[Loloflatsix]

The pathway looks very similar to the X299 but there are a few differences :
- There are specific kernel patches xcpm_core_scope_msrs and xcpm_SMT_scope_msrs to add to config.plist, some are relevant to the OSX version you are going to install.
- Another point about BIOS firmware provided by the different Mainbaord manufacturers : to overcome CPU performance issue (with or without overclocking) , an Intel CPU microcode update within the respective BIOS firmware distributions is mandatory.
