Hi, I have a question which I have for a very long time now. I own a Macbook Pro Retina 15" Early 2013, and since I have the Macbook, I experience some weird lag in launchpad, mission control, and in the raster application folder in my dock. I am running Mac OS X Yosemite DP6, but it has been there with Mountain Lion, and Mavericks too. I have found one solution for now, and that is running running Photoshop CS6. When I run PS, it starts to get all smooth, which is... quite odd in my opinion. But I am really wondering if there is another solution than running PS to get rid of the lag in launchpad, mission control and the application folder in my dock. I have been looking around for a long while now, but cannot seem to find anything which actually worked. (Like cleaning VRAM). I hope someone else can help me out with some suggestions. Thanks a lot in advance.
