Short description of error
Blender crashes immediately upon entering sculpt mode.

There is no "Blender quit unexpectedly" dialog, and no .crash file under {nav ~/Library/Logs/DiagnosticReports/} as described here: https://docs.blender.org/manual/en/latest/troubleshooting/crash.html
Loading factory settings via {nav File>Defaults>Load Factory Settings} does not prevent the crash.

Most likely caused by 65900d88a8 but it seems the developer just fixed this with 0de9081e89 but I'm not sure.
