Hi Stockie,
macOS Sierra (10.12) or later is required for the current jammr release (1.2.8).

If you want to try out older releases they are still available, but you will see a message prompting you to upgrade every time you start the program. This is because we do not support old versions and sometimes need to make incompatible changes that can prevent old versions from working.

You can find the old releases here but they are unsupported and may have known issues that have since been fixed:

https://jammr.net/static/1.2.4/jammr.dmg
https://jammr.net/static/1.2.3/jammr.dmg
https://jammr.net/static/1.2.2/jammr.dmg

If you are a developer you can also try building the latest jammr source code on the old machine. I cannot guarantee that it is possible because it may use features that are unavailable on older operating systems. It can take quite a bit of time to do this sort of thing, so I would only do it if you are a software developer who is up for a challenge . The source code is here:
