There is but only on Patreon (still free if the update is already public don't worry)
It's just that I don't have a mac myself, can't test anything so I don't publish it anywhere else since it might just be full bugged and so on.

For the special chapters : https://mega.nz/file/JzxnEY4C#fVH7y-KReJefLy5Mm8hXiwjiYMDZFWkCC-OCm0OzAeM
