I recently updated by MacBook Air to macOS Sierra Version 10.12. I am using Greenfoot version 3.0.4 (Java version 1.8.0_92).
I am working on building a piano. When I hold down a key on my keyboard to play a sound, it either repeats the sound file in a frantic manner, doesn't play, or delays to play it. Also, once I hold down a key, it will play the sound once but won't again until I restart Greenfoot.
Could this problem be due to the updating of my computer?
