+additional = """The issue is coming from the `os_setup_limits()` function in `os-posix.c`. As it turns out, the `setrlimit()` syscall behaves subtly different on macOS than on Linux systems, and the macOS man pages explicitly forbade the code on line 273.

+Line 273 from `os-posix.c`:

+nofile.rlim_cur = nofile.rlim_max;

+macOS `setrlimit()` man page:

+```
+COMPATIBILITY
+     setrlimit() now returns with errno set to EINVAL in places that historically succeeded.  It no longer accepts "rlim_cur = RLIM_INFINITY" for
+     RLIM_NOFILE.  Use "rlim_cur = min(OPEN_MAX, rlim_max)".
+```
+
+The man page thankfully gives us the [patch](/uploads/e7c8c6e3b5620c3b1ee34e89661097f3/qemu.patch)"""
