I don't know. Somehow it happens recently. I did paste it into Gemini 2.5 Flash  and it does know it is a KP. Here is the diagnosis by:

 

This log indicates a **kernel panic** on a macOS system. Let's break down the key information:

*   **`bug_type: "210"`**: This typically refers to a kernel panic.
*   **`timestamp: "2025-07-26 07:35:04.00 +0800"`**: The exact time of the panic.
*   **`os_version: "macOS 13.7.6 (22H625)"`**: The macOS version running at the time of the panic.
*   **`macOSPanicString`**: This is the core of the problem.
    *   **`panic(cpu 0 caller 0xffffff80161b1343): Kernel trap at 0xffffff80161371c2, type 13=general protection, registers:`**: This is the panic message itself.
        *   **`Kernel trap at 0xffffff80161371c2`**: The address in the kernel where the trap occurred.
        *   **`type 13=general protection`**: This is a **General Protection Fault (GPF)**. In the context of a kernel, a GPF means the CPU detected an invalid memory access or an attempt to execute a privileged instruction from a non-privileged mode. This is a severe error that the kernel cannot recover from, leading to a panic.
        *   The subsequent lines list the CPU registers' states at the time of the panic, which are crucial for low-level debugging.
    *   **`Panicked task 0xffffff9a02d3f8b8: 217 threads: pid 0: kernel_task`**: The panic occurred within `kernel_task`, which is the macOS kernel itself. This means the problem is deep within the operating system, not an application.
    *   **`Backtrace (CPU 0), panicked thread: 0xffffff906a7730c8, Frame : Return Address`**: This is the call stack, showing the sequence of functions that led to the panic.
        *   `0xffffff8015d0c6d0 : 0xffffff80161371c2` is the immediate caller of the instruction that caused the trap.
        *   The addresses like `0xffffff801606cc7d`, `0xffffff80161c1394`, etc., are within the kernel and correspond to specific functions. Without access to the kernel's symbol table for this specific build (`22H625`), it's hard to pinpoint the exact function names. However, the consistent `0xffffff80` prefix indicates they are all within the kernel's address space.
    *   **`Boot args: swd_panic=1 alcid=99 agdpmod=pikera`**: These are the boot arguments passed to the kernel. `swd_panic=1` might be a debugging flag. `alcid=99` and `agdpmod=pikera` often relate to audio and graphics drivers/configurations, especially in Hackintosh setups or specific Mac configurations.
    *   **`Mac OS version: 22H625`** and **`Kernel version: Darwin Kernel Version 22.6.0: Thu Apr 24 20:25:14 PDT 2025; root:xnu-8796.141.3.712.2~1/RELEASE_X86_64`**: Confirms the specific macOS build and kernel version. The kernel was built on April 24, 2025.
    *   **`System model name: MacPro7,1 (Mac-27AD2F918AE68F61)`**: Identifies the specific Mac model. This is a Mac Pro (Late 2019).
    *   **`System uptime in nanoseconds: 12291647839564`**: The system was up for approximately 12,291.6 seconds, or about 3 hours and 25 minutes, before the panic.
    *   **`Last Sleep`**: Provides information about the last sleep/wake cycle, indicating the system had been put to sleep and woken up previously.

**Possible Causes of a General Protection Fault (GPF) Kernel Panic:**

1.  **Faulty Hardware:**
    *   **RAM issues:** Bad RAM modules can lead to data corruption or incorrect memory access, triggering GPFs.
    *   **CPU issues:** Less common, but a faulty CPU could cause invalid operations.
    *   **Peripherals:** Sometimes, issues with connected devices (e.g., external GPUs, specific USB devices) can interfere with kernel operations.
2.  **Corrupted System Files or Kernel Extensions (KEXTs):**
    *   A corrupted kernel file or a third-party kernel extension (KEXT) that is buggy or incompatible with the current macOS version can cause the kernel to access invalid memory or execute bad code. Given the `boot args` (specifically `agdpmod=pikera`), there might be custom KEXTs related to graphics.
3.  **Driver Issues:**
    *   Problems with graphics drivers, network drivers, or other hardware-related drivers can lead to kernel panics if they attempt to perform illegal operations.
4.  **Software Bugs within macOS:**
    *   While less likely to manifest as a direct GPF in stable releases, a bug in macOS itself could, under specific circumstances, lead to such an error.
5.  **Overheating:**
    *   Extreme overheating can lead to hardware instability and unpredictable errors, including kernel panics.

**Next Steps / Troubleshooting:**

1.  **Check for Software Updates:** Ensure macOS is fully updated.
2.  **Run Apple Diagnostics:** Restart your Mac and hold down `D` during startup to run Apple Diagnostics. This can help identify hardware issues like RAM problems.
3.  **Check for Third-Party Kernel Extensions:**
    *   Given the `agdpmod=pikera` boot argument, it's highly likely there are custom or third-party KEXTs involved, possibly for graphics card compatibility (Pikera is often associated with Metal compatibility for certain GPUs).
    *   If you've installed any non-Apple KEXTs, try disabling or removing them to see if the panic stops. This can be complex and requires caution.
4.  **Test RAM:** If Apple Diagnostics doesn't find issues, consider running a more thorough memory test if possible.
5.  **Monitor Temperatures:** Ensure your Mac is not overheating, especially under load.
6.  **Review Recent Changes:** Did you install any new software, hardware, or drivers just before this started happening?
7.  **SMC and PRAM Reset:** Sometimes resetting the System Management Controller (SMC) and PRAM/NVRAM can resolve unusual system behavior.
8.  **Reinstall macOS:** As a last resort, if software corruption is suspected and other troubleshooting fails, a clean reinstall of macOS might be necessary (back up your data first!).

The `General Protection Fault` is a low-level error indicating a serious issue, often with hardware interaction or a fundamental software component like a kernel extension. The presence of `agdpmod=pikera` strongly suggests investigating graphics-related KEXTs or configurations as a potential culprit.

 

 

Too general but it is a GPF.

Hi,
 

Quote

Boot args: swd_panic=1 alcid=99 agdpmod=pikera

System model name: MacPro7,1 (Mac-27AD2F918AE68F61)`**: Identifies the specific Mac model. This is a Mac Pro (Late 2019).

 

Make sure to have the latest OC & kexts versions.
Also, try to boot w/o WhateverGreen.kext as you have MacPro7,1 SMBios
Boot args: -v keepsyms=1 debug=0x100
Misc > Debug > AppleDebug & ApplePanic on True and Target=67 
Misc > Security > ScanPolicy 0; SecureBootModel Default; Vault Optional

P.S: You can share your EFI folder?
