Is there a way to retrieve memory pressure information from macOS using Swift or C/C++? In Activity Monitor, there’s a chart labeled “Memory Pressure” which provides a discrete metric of RAM usage: Green = system memory usage is fine Yellow = moderate pressure Red = high memory pressure I’d like to know how to programmatically access this metric.

When I run this command, the value looks a bit strange. Sometimes it returns 0, and other times it shows unexpected numbers like 1725 or 1012. What exactly does this information represent? I just want to retrieve one of the three possibles values for the memory pressure information (ok, warning, critical).

Is there any way to retrieve the memory pressure percentage using native libraries? When I run the memory-pressure command, I can see the percentage of free memory, but I’d like to retrieve the same information using a native library.
