That's a new one. I've started using Ruby from homebrew a while ago, so I hadn't tested Gosu with High Sierra's built-in Ruby installation. I'll play around with it and see if I can get it fixed.

Fixed by disabling a warning(?!) as seen in this other issue: brianmario/charlock_holmes#122

[jlnr]

I have released Gosu 0.13.2 to address this issue. Thanks for reporting this pretty embarrassing showstopper! 😰
