I am making a little application with three NSButtons with an image set. These buttons have no border nor background. However, when I click a button it turns into a gray rectangle.

How can I fix this? Thanks.

Make your button type as NSMomentaryChangeButton. 

[myBtn setButtonType:NSMomentaryChangeButton];

If you use NSMomentaryPushInButton then you may get gray rectangle over the button when click.
