MacBook Pro M2 Pro (2023) with Critical ANS2 Failures – Repetitive Kernel Panic

Hello everyone,

I'm having very serious issues with my 2023 MacBook Pro M2 Pro (out of warranty), which keeps rebooting itself several times a day with various kernel panics linked to the internal storage subsystem.

I reinstalled macOS from scratch and ran Apple Diagnostics (result: ADP000, no errors), but the problem persists. I've received these error messages, among others:

ANS2 Recoverable Panic - apcie0[0]: 2/2 links are down, ltssm=DETECT_QUIET - Null(4)

SOCD report detected: iBoot panic

I'm also seeing this consistent pattern: RTKit: Client: AppleStorageFirmwarePreASP3, and several logs detail a lost PCIe connection between the M2 chip and the ANS2 storage controller.

The device worked fine for a couple of days after the reinstallation, but then crashed again with random reboots and serious firmware errors.

I've documented more than five kernel panics with the same symptoms. From what I understand, this indicates a hardware failure at the level of the integrated storage controller.

My question is:

Has anyone experienced this type of failure on similar devices?

I've seen various types of ANS2 Kernel Panics on this forum. While many of them may be due to the internal SSD, some of them have also been associated with an external Thunderbolt drive.

Has Apple recognized cases of this type as manufacturing defects, even outside of warranty?

Not that I am aware.

I appreciate any guidance or similar experience that would help me resolve this. I'm in Uruguay and plan to contact technical support with the full history, but I'd like to know if there are precedents or recommendations from the community.

Disconnect all external devices just in case one of them is causing a problem.

The best test you can do is to perform a DFU Firmware Restore which resets the security enclave chip, system firmware, and internal SSD as well as pushing a clean copy of macOS onto the internal SSD. Unfortunately this process requires access to another Mac which is currently running macOS 15.x Sequoia.

Test the computer in this state before installing any third party software or migrating/restoring from a backup. If you still receive the ANS2 Kernel Panics in this configuration, then you have confirmed a hardware issue exists with the computer's Logic Board. This is your best hope of getting Apple to repair the laptop since Apple techs are not familiar with interpreting Kernel Panic reports.

When contacting Apple support, they will have you go through a bunch of steps such as reinstalling macOS. So if you can test the Mac with a clean install (erase the disk & reinstall macOS) or the DFU Firmware Restore, then you can skip some of the back & forth of low level tech support and get to an engnieer who can actually examine the Kernel Panic logs.

Here is a post by another respected contributor for dealing with Apple under these types of issues:

Amazing work there my friend 👍
