While many things work in the binary macOS app for Arm CPU, I discovered by 
accident that the following produces a segfault:

sage: M = Manifold()

In fact, even trying to import manifold from sage.manifolds segfaults.  
This does not happen on the Intel version of the app built from the same 
branch of the repository.

I have not been able to run a debugger on sage at all.  Of course cysignals 
cannot produce a backtrace on macOS.  With lldb -p I get an error saying 
that lldb is not allowed to attach to the process and referring me to 
non-existent messages in system.log for explanations.  Running the 
debugserver directly produces:
error: failed to attach process 6619: unable to start the exception thread

This occurs even if I run sage directly in the repo after the build 
finishes - it does not have anything to do with the app.  (And the debugger 
similarly refuses to attach to the process.)  I tried to run the debugger 
as root and I also tried adding debugger entitlements and resigning the 
app.  Neither make it possible for me to use lldb on sage itself.

I am able to start the sage python3 in lldb.  If I knew how to import the 
Manifold class from python I might be able to get somewhere.  But if I run
>>> from sage.manifolds import manifold
I get a python exception whose traceback ends with:
File "sage/structure/category_object.pyx", line 60, in init 
sage.structure.category_object 
(build/cythonized/sage/structure/category_object.c:9914)
ImportError: cannot import name Category
