Just downloaded Mewn Base today for the Mac. Unzipped, double-clicked icon to install, and nothing. The game will not install. It flashes once like something is happening, but that is all. Anyone else having trouble installing on a Mac?
Sorry you're having trouble. itch.io is a platform that hosts almost 100k games. Our public community might not be the best place to get support for a particular game.
In any case, if you're having trouble, I recommend installing with our app since it will download and extract games for you without any mistakes: https://itch.io/app
It can't fix a broken game though, and in that case you'll have to contact the developer of the game.
