sysctl vm.memory_pressure
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).

How to retrieve device model name via sysctl
Model Name: MacBook Air Model Identifier: Mac17,3 I know it's possible to retrive model-identifier by running the command "sysctl hw.model", but is there another key to retrieve the model-name? ("MacBook Air" instead of "Mac17,3")

How to retrieve the % of memory pressure using native libraries
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.

How to retrieve the memory pressure information from macOS
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.
