Re: [sage-support] Re: Install of sage on macOS

[G. M.-S.]

Hi Dima.

As you said, "brew install sage" does nothing more than downloading a
sage-*.app.dmg and copying it to /Applications, at least on an older OS.

Details follow for macOS High Sierra (10.13.6).  Yes, I know it is an
"obsolete" version.

$ brew info sage

sage: 9.1,10.11.6

https://www.sagemath.org/

Not installed

From: https://github.com/Homebrew/homebrew-cask/blob/HEAD/Casks/sage.rb

==> *Name*

Sage

==> *Description*

None

==> *Artifacts*

SageMath-9.1.app (App)

/Applications/SageMath-9.1.app/Contents/Resources/sage/sage (Binary)

==> *Analytics*

install: 261 (30 days), 529 (90 days), 1,740 (365 days)

$

One can see in the file
https://github.com/Homebrew/homebrew-cask/blob/HEAD/Casks/sage.rb
that it downloads
https://mirrors.mit.edu/sage/osx/intel/sage-9.1-OSX_10.11.6-x86_64.app.dmg
or
https://mirrors.mit.edu/sage/osx/intel/sage-9.2-OSX_10.15.7-x86_64.app.dmg
(which will not work for recent OS).

I tried to install it:

$ brew install sage

[…]

But it is quarantined:

lrwxr-xr-x@   1  28 Dec  4 01:39 sage -> Contents/Resources/sage/sage

com.apple.quarantine   67

$

and you get the classical

*“SageMath-9.1.app” can’t be opened because the identity of the developer
cannot be confirmed.*

Opening it anyway, it is exactly the same as downloading the .app.dmg
yourself (which I had already done).

I do not know if Homebrew does something more on a more recent OS.

P.S. After some trial and error, I have managed to
install sage-9.2-OSX_10.15.7-x86_64.app.dmg on macOS 10.13.6, but I would
be unable to say what made it work.

on macOS 10.15.7 this appears to install the version 9.2 of  x86_64.app.dmg
by
pulling it from a Sage mirror.

Does Sage installed this way work?
(I'd be surprised it was the case)

[sage-support] Re: Install of sage on macOS

[Mathieu Dutour]

Thank you for providing this. Keep that in mind for future.

As it turns out, the solution to installing was incredibly simple:
"brew install sage"

I think this should be mentioned on the "Sage Installation Guide"
as this is a very convenient and standard procedure on Macintosh.

Your mention of "sudo xattr ..." should be mentioned as well
I think.

[sage-support] Re: Install of sage on macOS

[john_perry_usm]

Have you tried this?

   sudo xattr -r -d com.apple.quarantine 

It removes the "quarantine" signal on files. I used it to get Sage running 
on Catalina. I've had to use this with some other things, too. I learned of 
it through one of the StackOverflow sites, and it may also be in Sage's 
documentation somewhere.
