Installing SageMath on macOS Big Sur 11.1

[Arpita Korwar]

Hello all,

I am running into a problem while installing SageMath on my laptop.

The operating system is: macOS Big Sur 11.1, 64-bit.

sage-9.2-OSX_10.15.7-x86_64.dmg was downloaded on torrent. The seed was taken from http://mirror.aarnet.edu.au/pub/sage/torrents.html

Then, the SageMath folder was copy-pasted into the Applications folder.

To open the file, double click on sage file in the folder. MacOS could not verify the developer. I have to “Open” it anyway. Then, another pop-up says “This file cannot be opened because the developer cannot be verified.” Then, I have to go to system settings , Security and Privacy, and click “Allow Anyway”. I did this innumerable times for various files. Still, it keeps coming up with more files whose developer it cannot recognise.

Any help would be welcome. I am attaching some screenshots and the crash report herewith.

Thank you in advance,

Arpita

Supporting macOS 11 Big Sur is tracked at

- Sage Trac ticket 30651

  Meta-ticket: support macOS 11 Big Sur

  https://trac.sagemath.org/ticket/30651

Binaries for Sage 9.2 from the Sage download website

will not work for macOS 11 Big Sur. Hopefully we will

be able to provide Big Sur binaries for Sage 9.3

In the meantime you might be able to install Sage via Conda

based on Miniforge, a Conda distribution that already supports

macOS 11 and even the latest Apple M1 processors.

Hi,

I also posted recently about some of my attempts to get Sage running
on my Big Sur apple M1 macbook pro here a few days ago:

In particular,

... I actually found that the binary I downloaded did work, but see
the steps mentioned in my message.

There was a discussion about conda and Apple M1 and they specifically
said it does NOT work to build Sage,
but that there was progress and only a few dozen (?) packages still
need to be ported:

A lot of people will probably disagree with me, but my personal
opinion is that probably the best way to get Sage running on your Big
Sur laptop is via Docker desktop, which is well supported by Docker
for Mac OS (and Windows). See also
https://hub.docker.com/r/sagemath/sagemath/. This is most likely to
work well, but requires that you learn the basics of Docker.

For what it's worth, I was able to build Sage on 11.0 using homebrew, but since the upgrade to 11.1, the build fails for me. Discussion at #30651 (started at #30589, but should be continued at #30651).
