> Rhys,
>
> I have been working on a series of patches based on your GitHub repository
> that allow Valgrind to work on macOS Mojave (albeit fairly experimentally).
>
> The following are included:
> - Empty stub for `mach_msg_destroy` which is required by the new mig
> - A bunch of suppressions for dyld related functions (which are probably
> way too generic)
> - `openat` support
> - `thread_get_special_reply_port` support
> - Output/check improvements for a handful of syscalls
> - Multi-threading support (signals are still buggy)
>
> I also added a README.md containing the result of `make regtest` for
> reference.

I can confirm that this installed successfully for OSX 10.14, but the leak
report didn't look right, I know I had memory leaks but it was showing 0 bytes
of loss. I upgraded to OSX 10.15 and now the binary errors with the following:
