If the "SSE2" version fails like that, then it's not actually SSE2 -
it's probably more like SSE4.  Your Core 2 Duo supports up through SSSE3
inclusive, but not SSE4.  These are recent user-contributed builds, so
it's likely that the contributor didn't consider recent macOS'
assumption that SSE4 has to be available for that OS anyway.

"V3" certainly won't work on your computer - it needs even newer (AVX).

I went ahead and renamed the files as follows:

mv john-1.8.0.9-jumbo-macosx_v3.zip john-1.8.0.9-jumbo-macosx_avx.zip
mv john-1.8.0.9-jumbo-macosx_sse2.zip john-1.8.0.9-jumbo-macosx_sse4.zip

based on user reports so far.  Maybe this will help reduce further
confusion, although few users appear to know what AVX and SSE4 are.

Right.

Please try to post fewer messages - try multiple things at a time, then
post.  We're bothering a lot of people with this discussion right now.
That's what this list is for, so the "bothering" is OK, but grouping the
information in fewer messages is preferable.

Yes, it did dump a lot of stuff, but not what we needed.

You mean the hash.  Yes, it should be, but we haven't seen it yet, nor
its corresponding salt.

None of this has dumped the hash yet, as far as I can tell.

They were not supposed to be directly usable with John, except for
xpwdump's output, but that one failed for unknown reasons.  Possibly
something is corrupted on the system.

Do you have anything under /private/var/db/shadow/hash at all?  For
example, try this command:

ls -R /private/var/db/shadow/hash

You didn't mention how you felt about that.  Sorry to hear it's this way.

Back to one of my previous questions: why are you doing this?  Aren't
you able to access the system anyway?  What's your ultimate goal?
