Crashes around the same block and on restart:

There's an issue with the latest macOS version that we didn't figure out yet.

Workaround is to use an older SDK

You can download the older SDK from here: https://github.com/phracker/MacOSX-SDKs/releases/tag/11.3

Alternatively you can disable RandomX JIT with: MONERO_RANDOMX_UMASK=8 env var.

Just throwing in some keywords to help anyone else searching (and missing) with segfault or segmentation fault. Thanks for your help in the chat @selsta

We found the issue, a fix will be included in the next release: tevador/RandomX#281

I can confirm that the the latest git rev works on my Macbook Air M1, whereas the latest release (0.18.3.1) was consistently crashing with a segmentation fault.
