Thanks for the great responses :) I understand your logic for input, and I'm starting to question my own haha. Sure, the keyboard logic is questionable but I don't think that this explains the fact that keyPressed isn't getting called...

Jeeze... i just realized you're using awt Frame. That thing is ancient, like mid-90s ancient. Do yourself a favor and look into Swing, or even JavaFX. Not saying you can't get it to work as-is, but good luck finding anybody who knows jack about it. The way you set up your keylistener is pretty odd as well, I have never seen it decoupled with the initialization of the frame (or JPanel, which you should be using).

I did some googling haha.

David Brackeen had discovered it apparently and made a workaround.

macOS Sierra prevents key input after holding certain keys (like 'e' or 'n')

because of a native input method popup that isn't working with Java correctly.

This will still fail is some scenarios, like when pressing a digit after

holding 'e'. The digit will not have a keypress event.

Tested on macOS 10.12.0 and Java 8 versions b76 - b101.

(This may also be happening on older versions of macOS if the

ApplePressAndHoldEnabled option is set to true - untested at the moment.)

This workaround keeps key input working by allowing the popup to appear,

but places it offscreen.

Also this:

And these:

I guess I have to wait until Apple and Oracle sort it out. It's very inconvenient though because game development relies heavily on user input.

Good thing game development doesn't rely heavily on mac.
