Sage_MacOS

The Sage_MacOS project aims to provide a simple, streamlined macOS application which runs SageMath and can be installed by the usual process of dragging the application bundle to the /Applications directory. There is a signed and notarized release of such an app for the current version of SageMath available in the Releases section, which is accessable from the right hand side of this page.

The structure of the application bundle is that the main executable is a small C program which execs the sage python interpreter to run a small tkinter application. The Frameworks section of the bundle contains frameworks for Tcl, Tk and Sage. The Sage framework contains the result of a standard build of Sage with inessential components removed. Executables and libraries in the framework have modified load paths and rpaths designed to make the framework fully relocatable and self-contained to allow for signing and notarization.

The application opens a small window which can launch Sage, either as a command line program or as a Jupyter notebook. The command line interface can run either in Terminal.app or, if it is installed, in iTerm.app. Once Sage is launched, the app exits. This behavior is similar to that of Apple's Launchpad.app. The application icon can be placed in the dock to make it easy to launch Sage at any time.

The distrubution includes an Installer package which creates an executable bash script named /usr/local/bin/sage that can be used to run sage from a shell or script. It also installs Jupyter kernel descriptions in a standard location in /usr/local to enable Jupyter applications to run Sage.
