You need to understand what GraphicsEnabler=Yes does , or what is set to No does.Graphics enabler is a feature of Chimera that will "patch" your graphics card string from a DB.Essentially MacMan and TonyMac update the list of cards so OSX will then load the native drivers.YOU WANT TO RUN WITH GRAPHICS ENABLER=NO if you can!!!!Since this means OSX will simply just work with its own drivers no need to patch a thingYou can also use graphics enabler=yes but chances are your card isn't in the updated in the DB.Its like making 3 left turns to go the right way , why waste you or your computers time on extra worthless steps.Not to mention running graphics enabler when its not needed can cause problems
