This problem was reported to us by Arturo in the comments section of our macOS 12.0.1 review page:

“I’m frequently getting the ‘your system has run out of memory’ warning since updating! I don’t perform any resource intensive tasks.”

  • Apple’s Discussion Forums:

    “I have started receiving this error message frequently. Can’t understand why. I have 16GB of RAM and activity monitor typically shows plenty of RAM available.”

  • Reddit:

    “Your system has run out of application memory on m1 Mac mini”

  • Twitter:

    “So glad I got 64GB of memory on my new Mac so I can use 26GB of it for control center… Wait… what.”

Conclusion: A macOS 12.0.1 memory leak issue is affecting a wide range of Macs including the new 14″ and 16-inch MacBook Pro 2021! Light native apps such as Control Center, Calendar or popular third-party apps like Firefox can end up using tens of GB!
