I packaged Forscan into custom Homebrew tap which allows using it easily on Macbooks as well.

This is most likely the easiest way to run Forscan on MacOS. So I would recommend following these steps:

1. First install homebrew from: http://brew.sh
2. Then copy following command into Terminal:

brew install --no-quarantine --cask wine-stable onnimonni/tap/forscan

3. And after this plug your cable to the car and your laptop and launch FORScan.app in your laptop from Applications.
