A Derivation Planner installer can be downloaded from here Derivation Planner Mac Universal . This installs an app that runs on Mac computers (both Intel and ARM). The software is signed and certified by Apple. (Mac computers will detect that and allow it to run.)
Shortly there will be a similar signed and certified installer for Windows computers.
Both Mac and Windows versions will be available from their relevant app stores.

Arrange the settings as you would wish to have them
Derivation Planner can run eight or more different logical systems. It won't know 'out of the box' what configuration you would like. Please do an initial set up.
There is a Settings menu item under the Derivation Planner Menu.
