Have you had any Mac Bugs?

I've noticed many little bugs throughout my 2 years of playing League on a Mac. Many are just small little nuances that I usually ignore. But I wanted to see if we could get a list from all the Mac users out there! So here are some that I have noticed:

1: When using Semi-Locked camera mode, you cannot center the camera on your champion with spacebar (or any other key) 2: When launching League, the launcher and the client will both open on the last desktop that you were active on, instead of the current desktop that you are viewing. 3: "Another instance of the launcher is running. Do you want to terminate it?" comes up often when trying to re-launch the client.

**What other Bugs have you been dealing with for a long time? **

@Riot Apple has announced their new Metal API (https://developer.apple.com/metal/). Are you looking into utilizing its advantages? Is there anything great that it will do for League?

I am on OSX 10.10.5
