Recently, code to get the memory usage of the current process was removed from the GC: https://github.com/python/cpython/pull/149475/changes#diff-4722ae850a2da3e12f50815c0e3932627ebe67edeaa8b7f28a94f20c8698204dL2022. I used task_info(mach_task_self(), TASK_VM_INFO, ...) and gets vm_info.phys_footprint. In private, @corona10 told me that task_info() cannot be used to get the memory usage of other processes.

psutil also uses proc_pidinfo(PROC_PIDTASKINFO) API to get the RSS memory of a process: https://github.com/giampaolo/psutil/blob/1a2569db0b2ad7489539ad6b6b6b85cb13b755f7/psutil/arch/osx/proc.c#L136-L154.

You should run make clinic, no?

[corona10]

You should run make clinic, no?

Why? I didnt use AC at here

[vstinner]

LGTM if the macOS jobs in GitHub Action and macOS jobs on buildbots are happy with this change.

I don't have access to macOS to test the PR.

Why? I didnt use AC at here

Oops, you're right. I was confused by other C functions using AC.

Thanks for adding macOS support!
