Installing Manager on an old version of Mac OSX

I am running an old version of Mac OSX, version 10.10.5, and I’m looking for a way to install a version of Manager that works on my computer. Upgrading to a new operating system doesn’t seem to be an option—I’m stuck with this one. I’ve seen the folders of old files available on Github, but they seem to just be collections of files, rather than an application. I’d love some guidance.

This will be tough. I’m not sure myself how far back you need to go to get 10.10.5 support. Also, we do not support older versions.

If upgrading Mac OS X is not an option, can’t you install some Linux distribution as dual-boot option and use Manager on Linux? That way you could have the latest.
