There is no communication between ElCapitan and Mohave via the suggested version for El Capitan (V15.2)
Hello @paul3441,
Just wanted to ask you if you could solve your connection problem.
Were you able to solve it? If not, please let me know. 🎅❄
You seem to have an issue when connection from a Mac that has ElCaptian and another Mac that has Mojave.
Could you please tell us a little more about the issue you are having?
Maybe sharing a screenshot or an error message would help us to understand why you can't connect?
