On my Mac I tried to change the controls on input before I hit play but when I went to change the controls I double clicked and it made it the left mouse. When I tried changing it back by clicking the new key but it won't work. Ive redownloaded the game a couple of times ones and it still hasn't changed
Hey we are not sure how to do it on Mac but on windows you can delete Raft in the windows register at this location
HKEY_USERS/S-1-5-21-2230790418-1291474799-221512870-1000(Or similar)/Software/Raft
If you can find the similar place on Mac and just delete the Raft folder the game will create a new one when you start the game.
