[b]UPDATE:[/b] This issue should now be fixed, please update your game and sorry for the inconvenience.
Sorry everyone, it has been brought to our attention that on some version MacOS there is an issue preventing right clicking using a trackpad. We are working on a fix at the moment and anticipate uploading it tomorrow (Thursday 8th December).
Sorry for the inconvenience, in the meantime a work around is to use a Bluetooth/ USB mouse or gamepad. We will upload a fix as soon as possible, thanks for your patience.
