I just came back to play Eve again and notice the same issue with my iMac and want to resolve it.
Everything works fine except for my mouse wheel zoom when in space. The slightest change makes me either zoom up close at my ship, or to the extreme zoom out. I use the original Mac mouse with the silly little mouse ball on the top.
I do not want to change the mouse, because it works great when using my art applications.
Do I need to install a third-party mouse controller ? If so, wanna recommend one to me. I have OS X Sierra currently installed.
