Random System Freezes on macOS After BIOS Update (ASUS Z890 / Arrow Lake Hackintosh Issue

[Zanko Film]

Hello everyone,

I'm experiencing random hard freezes on macOS after updating my motherboard BIOS, and I'm hoping someone can help identify the cause.

System Specifications

• Motherboard: ASUS PRIME Z890-P
• BIOS Version: 3012
• CPU: Intel Core Ultra 5 225F (Arrow Lake)
• GPU: AMD Radeon RX 580 8GB
• RAM: 16GB DDR5
• SSD: Lexar NS100 512GB
• SMBIOS: MacPro7,1
• OpenCore: (please insert version)
• macOS Sequoia 15.x
• macOS Tahoe 26 Beta

Problem Description

Before updating the BIOS, both macOS Sequoia and macOS Tahoe were running perfectly stable using the exact same EFI and OpenCore configuration.

After updating to BIOS version 3012, both operating systems became unstable.

The system boots successfully and reaches the desktop without any issues. However, after approximately 10–20 minutes of use, the entire system freezes.

Symptoms

• Mouse and keyboard completely stop responding.
• Caps Lock no longer responds.
• Audio sometimes loops/repeats for a few seconds before the freeze.
• In some cases the system remains frozen indefinitely.
• In other cases it eventually reboots.
• The issue appears more frequently while opening or using applications.

Troubleshooting Already Performed

• Reset NVRAM
• Disabled Secure Boot
• Disabled Fast Boot
• Disabled VT-d
• Disabled VMD / Intel RST
• Removed a suspected failing HDD
• Checked CPU temperatures (typically between 50–57°C)
• Verified that Windows runs completely stable on the same hardware
• Tested both macOS Sequoia and Tahoe
• The exact same EFI was stable before the BIOS update

Additional Notes

• SMBIOS is MacPro7,1
• RX 580 is detected correctly
• macOS boots normally and reaches the desktop
• No obvious kernel panic is displayed during boot
• Both Sequoia and Tahoe are affected
• The problem started immediately after updating to BIOS 3012

I have attached my current EFI/config.plist for review.

I would greatly appreciate it if someone could take a look and help identify the cause of these freezes. Since the exact same EFI was completely stable before the BIOS update, I'm wondering whether BIOS 3012 introduced ACPI, CPU power management, CFG Lock, or OpenCore compatibility issues on Z890 / Arrow Lake systems.

Has anyone experienced similar behavior after updating the BIOS on an ASUS Z890 motherboard?

Any help or suggestions would be greatly appreciated.

Thank you very much for your time and assistance.

Its hard to check it. All asus z890 is very problematic. Extract one full dump with this command and lets try check it

ASUS_Z890_Freeze_Diagnostics-Release.zip

and post one full dump with this too https://olarila.com/files/Utils/DumpGenerator-Release.zip

I've created the full dump using the tool you suggested and attached it here.

Thank you for helping me with this issue and for taking the time to look into it. I really appreciate your support.

Let me know if there's anything else you'd like me to provide.

Thanks!

The .command don't generate?

Some points

Disable VMD / Intel RST / VMD Controller in BIOS.
This is the main suspect because the dump shows PCH RP01-RP04 mapped under VMD.

Disable ASPM / PCI Express Native Power Management / DMI ASPM in BIOS.
The hard-freeze pattern is compatible with an incorrect PCIe power-state transition.

AppleAHCIPort plus the 8086:7f62 Arrow Lake SATA controller being spoofed as 8086:8c02.

Do u use zeroprpm on RX580?

Disable Serial Port / COM Port in BIOS.
This removes Apple16X50ACPI and the fake PPP serial network ports from macOS, reducing unnecessary ACPI/device noise.
