	pprint(":warning: [bold red] Memray support in MacOS is still experimental [/]:warning:", file=sys.stderr)
	pprint("[yellow]Please report any issues at https://github.com/bloomberg/memray/issues[/]", file=sys.stderr)
	pprint("", file=sys.stderr)

writes to stderr when running on macOS

My tests monitor stderr and fail when running with memray because stderr has unexpected output (the warning message)

Duplicate of #194 (which has #250 as a proposed solution).

We're trying to avoid adding an environment variable for suppressing warnings, since it requires manual steps to avoid the problem from the part of people using pytest-memray. That said, there are some drawbacks to just moving where we print the warning, too...
