10.6 crash after installation

[Justin C. Walker]

Hi, all,

I just installed 10.6 from the 3-manifolds site. My system is Mac OS Catalina, 10.15.7, on an Intel MBP (2019). Attached is the crash report. Immediately after I installed the tarball, I ran “sage”, and the attached is the result.

Help and pointers would be much appreciated.

Thanks!

Justin

Nothing attached.

We don't support such old, well past EOL, macOS releases.

Oops.  Dima’s reply explains all.

Thanks to you both.

Justin,

This is a known issue with the SageMath 10.6 binary [1], but SageMath 10.5 should work on your system.  

Best,

Nathan

Thanks, Nathan.  10.5 seems to be dysfunctional, but I am communicating with Marc to figure out if it’s a screwup on my end, or if there’s something rotten in DMG :-}

Hi, just for the record.

SageMath runs on macOS 10.13 and newer.

macOS 10.13, 10.14 and 10.15 are NOT "too old" for SageMath.

There was indeed a problem with SageMath-10.6_x86_64.dmg, which has been promptly corrected by Marc Culler in the following version.

Please get

SageMath-10.7_x86_64.dmg

from

https://github.com/3-manifolds/Sage_macOS/releases

Everything works, including JupyterLab notebooks.

Beware:  You are advised to use Firefox (version 115 ESR) instead of Safari or Chrome.

HTH,

Guillermo

Just to clarify, by "unsupported" I meant that we don't test on such past EOL systems, and cannot guarantee Sage would work on them.

Needless to say, these systems are a security risk for their users (they aren't supported by the vendor either).

[G. M.-S.]

Thanks Dima.

Perhaps it all boils down to the elements of the "we" set.

I am sure you yourself (and presumably other people) do not test and do not guarantee.

However, there are "some" people who do.  From which "we" set are you excluding them?

OTOH, "we all" know about old risks, new risks, and even 0-day risks.  Perhaps "some of us" use EOL hardware, for different reasons (including not having a choice).

Anyway, this is the last I am saying about this, not least because I greatly appreciate all your work for SageMath.

Best,

Guillermo
