macOS 26 Tahoe: System runs out of application memory (M4 Pro, 48 GB RAM, 2 TB SSD)

Dear community,


I recently bought myself a MacBook Pro with a M4 Pro chip, 48 GB of RAM and a 2 TB SSD hard drive.

It shipped with macOS 15.


After updating to macOS 26 I've experienced the following issues:


1) "Black screen of death" after system sleep

2) After wake up from sleep, I get the message "System has run out of application memory" and the system is completely unresponsive. (Can't check Activity Monitor for details because of that)


I have never experienced these issues with other Macs, and I am on my third Apple silicon machine now. I used the migration assistant to migrate the machine from my former M2 Pro machine.


Could this be a OS issue or is my new hardware faulty?


I attached a screenshot of the "application memory" message, but is in German.


Thank you, best regards


Michael

See if the problem is present when you boot in safe mode, which disables 3rd party extensions and performs some system cleanup.

FWIW, I have your configuration (16" M4 Pro MBP, 48 GB memory, 2 TB SSD). I'm running 26.0.1 (from this morning) and upgraded to Tahoe when it launched, and I've had no issues.

It is. Of course, some people prefer to view it as a place to blame Apple for the problems they are having with 3rd party software they've chosen to install on their system. Maybe Google can help you.

When dozens of users report the same problem

As others have pointed out, "dozens of users" means, statistically speaking - 0 users. And I'm not even sure what "problem" you're talking about. This is an 8 page rant thread. There's no problem anymore, just shouting.


the only response is "Apple is great, Apple is fair," I see a lot of similarities with a religious sect...

This is a pet peeve of mine. This accusation is typical for the internet. People in this forum and elsewhere complain about real Apple problems all the time. But strangely, no one care. No, I mean it. Absolutely no one cares about real-world problems with Apple.


Those problems that "get traction", that get boosted by social media influencers, are often entirely invented. In some cases, they are real issues in general, but they're issues where Apple actually performs very well, either compared to its competitors or objectively.


As a developer myself, these are the things that annoy me. If you pay any attention to the Apple developer social media scene, you will come away almost completely misinformed about the state of the Apple developer world. These aren't merely academic issues or people shouting at each other on the internet. The most misinformed, malign, and powerful people in the world, the politicians, are working very hard to make everything worse.

I'm not saying "Apple is great, Apple is fair". That's not true at all. But what you hear on the internet regarding Apple is about 90% opposite from what it is in real life, at least for the issues that I'm most familiar with.


Third-party developers don't invent things, they follow the operating system manufacturer's guidelines; evidently in this case (as has already happened in the past with other Apple-related applications, by the way), the guidelines differ slightly from reality.

Third-party developers most definitely invent things. Sometimes they follow guidelines, and sometimes they don't. Sometimes that's a bad idea, and sometimes it's not. But generally speaking, conscientious 3rd party developers try hard to ensure that their users have a great experience, by any means necessary. If Apple's APIs and guidelines get in the way, as they often do, then they'll be ignored, if possible. Trust me, sometimes it's an awful lot of invention and work to get an app running on an Apple device. Software that exhibits bugs, crashes, or a poor experience can only be attributed to the developer of that software, not to any other developer. That's true for 3rd party developers and for Apple.

Actually over 51 million developers.

Thank you for the more accurate information. I admit I didn't bother to do any research and also wanted to avoid hyperbole.

Other interesting data - over 146 thousand developer accounts terminated. But over 128 million customer accounts terminated.

Interesting indeed.
