Doing a search for the phrase "memory pressure" in the containing organisation (apple-oss-distributions) shows some relevant stuff: https://github.com/search?q=org%3Aapple-oss-distributions+%22memory+pressure%22 https://github.com/search?q=org%3Aapple-oss-distributions+%2... • memorystatus.md : https://github.com/apple-oss-distributions/xnu/blob/94d3b452840153a99b38a3a9659680b2a006908e/doc/vm/memorystatus.md?plain=1#L3 https://github.com/apple-oss-distributions/xnu/blob/94d3b452... # Memorystatus Subsystem Dealing with memory pressure by forcibly recovering pages.

Looks like the man page for a `memory_pressure` command • freezer.md : https://github.com/apple-oss-distributions/xnu/blob/94d3b452840153a99b38a3a9659680b2a006908e/doc/vm/freezer.md?plain=1#L8 https://github.com/apple-oss-distributions/xnu/blob/94d3b452... # Freezer Details of how some processes can be swapped out to disk. [...] The freezer is a limited form of swap on embedded. Under memory pressure, the freezer picks apps to freeze. (etc) And a whole bunch more. With some digging, it should be possible to find the exact info. :)
