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 […] ==> *Downloading https://mirrors.mit.edu/sage/osx/intel/sage-9.1-OSX_10.11.6-x86_64.app.dmg <https://mirrors.mit.edu/sage/osx/intel/sage-9.1-OSX_10.11.6-x86_64.app.dmg>* ######################################################################## 100.0% ==> *Installing Cask **sage* ==> *Creating Caskroom at /usr/local/Caskroom* ==> *We'll set permissions properly so we won't need sudo in the future.* Password: ==> *Moving App 'SageMath-9.1.app' to '/Applications/SageMath-9.1.app'.* ==> *Linking Binary 'sage' to '/usr/local/bin/sage'.* 🍺 sage was successfully installed! $ But it is quarantined: $ ls -al@ /Applications/SageMath-9.1.app total 0 drwxr-xr-x@ 4 128 May 23 2020 . com.apple.quarantine 67 drwxr-xr-x@ 6 192 May 23 2020 Contents com.apple.quarantine 67 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. Guillermo 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.
