Download FF++ for Mac

Dear FF++ users,

I tried to download the latest version of FF++ 4.8 for Mac from the FF++ homepage but unfortunately it doesn’t allow to install FF++.

  1. Can anyone please explain me how can I install the latest version of FF++ for Mac?
  2. Can anyone please recommend an editor for Mac in order to write a code in FF++?

Thanks in advance,
Mordechai.
