Running the game on my iMac with the Apple Keyboard. I have no issues with playing the PC version on Bootcamp, but on the Mac side, my character stops moving the moment I jump or tab to select enemies or NPCs. I have to release the key I'm using to move my character (in either direction), and press the key again to resume moving.

I don't know if it's a setting issue, however I've looked through the menus and cannot find anything that could be causing this.
