Mac is not officially supported due to this bug (the game is trying to save an image to your PC and Mac is blocking it because it is a third party software). You can try it out this advice:
Let Itch install the game for you. If you encounter an error when you try to create a character at the beginning of the game, please follow these steps:
- Click the Apple Icon in the top left corner.
- Go to System Preferences > Security & Privacy > Privacy > Accessibility > and allow the game to take control of your computer (checkmark must be off)
- Play the game again
If that still didn't work, you can try out this:
- Locate the folder Tailor Tales\Game.app\Contents\MacOS
- Open up the game by clicking the file "nwjs". This should open the debug window as well, simply minimize it and play the game as normal!
Or you can try and run a Windows emulator to run the game on Mac.
