Memory leaks in macOS 12

After updating to macOS 12 alias Monterey, users complain about applications that use significantly more RAM than usual. Apparently there are memory leaks in the system due to one or more bugs. According to reports in several forums, programs included in macOS such as the control center as well as third-party apps such as Firefox are affected. Sometimes so much RAM is used that the system spits out the error message that the application memory has been completely used up.

A machine from 2020 just stopped when upgrading, in other cases the boot process is not terminated after the import. Apple has not yet commented on this. (bsc)
