Why does my force trackpad make a buzzing sound when two finger scrolling in iBooks?
I have an Early 2015 MacBook Pro 13" with a force touch trackpad. When I two finger scroll in iBooks, the trackpad makes a faint buzzing sound. I'm using iBooks 1.2 (825). It doesn't make this sound when two finger scrolling in Safari. I don't mean scrolling a book. I mean scrolling the collection when I'm browsing which books I have.
MacBook Pro (Retina, 13-inch,Early 2015), OS X Yosemite (10.10.4)
