Stochasm is currently compiled for MacOS Mojave, though it should also work for some previous versions of MacOS.

To download Stochasm, click the link here:

Extract the .zip archive, if not already done automatically, to any directory you wish. Double-click the application to launch it.

Depending on your Mac’s security settings, you may encounter the following security warning when launching the application for the first time:

“Stochasm.app” is an application downloaded from the Internet. Are you sure you want to open it?

Click “Open” if such a button is provided. If not, then control-click (right-click) the application icon and select “Open”. This will provide a new dialog box in which you can click “Open” again to launch the application.
