MacBook Crash and Reboots while using Telegram, post macOS Sonoma latest update

I have exactly the same problem after updating to Sonoma 14.4. with my almost fully equipped MacBook Pro 16-inch M3 Max...

The update to Sonoma 14.4.1 has not brought any improvement either. In fact, it almost seems to have gotten worse. Acutely, the MacBook crashes and restarts every few minutes when using third-party software such as Steinberg Cubase, Maxon Cinema 4D, Native Instruments Komplete Ultimate... among others.

The error message after the hard crash and restart of the Mac is the same:

panic(cpu 0 caller Oxfffffe002a1001c): DCP PANIC - program_swap: Async Swap request landing on unsupported platform. Force panic

- iomfb_driver (10)...

I am in despair. This seems to be a macOS problem with the M3 Max chips.

@ CodeXT: Can you give me a tip on how you downgraded to Sonoma 14.3.1?

It is a display related issue. If it occurs with Telegram app, then make sure that the Telegram app is completely updated. If you still have the issue, then contact the Telegram developers for assistance. It is up to the Telegram developers to make sure their software works properly on the platforms they support (even if it is a macOS bug).

Edit: I said display issue, but in reality it is a GPU issue since DCP is the Display Co-Processor.

Since it started within installing a Steam game, you may want to check the Steam forums to see if others are having the same issue. You can also check the game's product page on Steam as well.

Just to clarify, did you already have Steam installed without any issues & you just installed a new game through your existing Steam client? Or was this the first time you installed Steam on this Mac? If the latter, then maybe uninstall Steam to see if the issue goes away. Keep in mind Steam and perhaps even some games may have components which are running in the background even when you are not using Steam or the game.

FYI, Games are always tricky, but even more so on a Mac....especially an Apple Silicon M-series Mac since you have all the normal game issues plus all the conversion issues such as Rosetta and Game Mode, etc. which are trying to make a Intel Mac game made for other GPUs work with a completely different CPU & GPU architecture. Macs really are not meant for gaming. It is great when it works, but gaming on a Mac is far from ideal.

I have the same issue, it started when I installed a Steam game (and the game optimized popup started showing up for the 1st time), not sure if its related but that's the only change in my system since it started happening.

M2 Pro Mini.

Same issue on M3 Pro (16"). Kernel panic within a minute of starting a Telegram call.

Problem:

After updating from macOS Sonoma 14.3.1 to 14.4, my new MBP crashes and reboots when using Telegram video calls. 

Usually, it happens when switching between windows and then back to the Telegram video call window.

The easiest way to reproduce is by running Civilization VI at the time of the call. For some reason, it immediately triggers the kernel panic crash.

Crash reports:

All crash reports start with “DCP PANIC - program_swap: Async Swap request landing on unsupported platform”, here are two examples:

Crash report 1

panic(cpu 1 caller 0xfffffe0013fe109c): DCP PANIC - program_swap: Async Swap request landing on

Concerns and Questions:1.

How can I be sure these crashes aren't caused by a hardware issue of my new M3 Max since the problem can't be reproduced on other MBP models? I would like to make sure of this while the laptop is still under warranty.

2. Is someone else having similar issues with M3 Max on macOS Sonoma 14.4.*?

Sounds like a GPU issue similar to @CodeXT with the Telegram app, or your external display. It is hard to say since we don't have your Kernel Panic logs.

Edit: Keep in mind, those Steam games were made for older Intel Macs so you cannot expect them all to work on an Apple Silicon M-series Mac. Games have always been tricky even when running on a Windows system with absolutely perfect system which exceeds the game's Recommended system requirements.

The thing is i get the panics even when no game is running.
