It works for me. But one thing is that if you build it with the macOS
11.x SDK it won't run on < 11.x. This is why apple recommends
something like:
if (__builtin_available(macOS 11, *)) {
pthread_jit_write_protect_np();
}
You still need a

It's not defined on my old MPB that has Catalina (10.15.7). The last
entries are:
#define MAC_OS_X_VERSION_10_15 101500
#define
MAC_OS_VERSION_11_0 is always defined. You can see in
usr/include/AvailabilityVersions.h
...
#define MAC_OS_X_VERSION_10_15 101500
#define MAC_OS_X_VERSION_10_15_1101501
#define MAC_OS_X_VERSION_10_16 101600

Pages can't be both write and executable at the same time on Apple

JIT applications, like TCG.
