Random freezes on Sonoma 14.5

Yes I did but I'm afraid the kext folder is a bit to heavy for the forum. Do you need the full kext folder ? Or the config.plist is enough ?

EFI is normally supposed to be under 25MB limit. A few kexts like Itlwm and AirportItlwm doubles the size. As per the feedback, users will soon able to upload upto 50MB.

Although a full EFI is required, you can omit the kexts which are of bigger size.

The EFI seems as per the guide and requires a few modifications only:

- You can fine tune by adding the MCHC (if the board doesn't expose one in IOReg or is MC which you can rename to MCHC).
- Another good advice would be to disable the ResizeAppleGpuBars using -1.
- You shouldn't require AAPL,slot-name for the Audio device.
- Kexts are not in sorted order. Mandatory kexts should load first.
- You should consider enabling the TRIM by setting the ApfsTrimTimeout to the macOS defaults using -1.
- Also, set the KernelArch to Any.
- As you're not using Hibernation, disable HibernateSkipsPicker.
- If you're not using Windows or Linux and/or don't need the IGPU there, you can disable it within the BIOS.
- Set the APFS MinDate and MinVersion to Auto.

The rest looks good!

Seems like the Samsung is causing issue. Cause, the KP is always from the IONVMeFamily itself. The Crucial P5 Plus is a retail version of Micron 3400 OEM (has same controller) and that's supported so is Crucial P3.

The WD Blue SA SATA SSD is also fine. The Crucial external will not use IONVMeFamily. The Internal HDD are fine as well. So, the Samsung seems to be culprit here. You would need to remove Samsung to narrow down the issue.

Hi !

You seem to have found the culprit. I didn't have crashes yet. Except when I installed a Crucial P3+ in replacement for the samsung that was formatted in exFat, after formatting it in APFS, seems to work properly. Tnanks !

Ragarding that, where can I find the info to understand what it is and how to do the changes ?

Glad to hear that the culprit was found!

All these changes has to be made in your EFI.
