+Mutex initialization assertion failure due to incompatibility with macOS setrlimit() syscall
+Description of problem:
+Running the command with with any set of arguments instantly crashes with the following error message:
+
+```
+Assertion failed: (mutex->initialized), function qemu_mutex_lock_impl, file ../util/qemu-thread-posix.c, line 92.
+zsh: abort      ./qemu-system-x86_64
+```
+Steps to reproduce:
+As per instructions for building from scratch:
+
+1. `mkdir build && cd build`
+2. `../configure --prefix=$PWD/.. --audio-drv-list=sdl --disable-cocoa --enable-sdl --enable-sdl-image`
+3. `make && make install`
+4. `cd ../bin`
+5. `./qemu-system-x86_64`
+Additional information:
+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)
