I used the brush Size Shortcut ctrl-opt-drag on lot on my Mac and it was working with Photoshop CS6 and Photoshop CC without any Problem. In Photoshop CC 2014 this shortcut does not work anymore. I'am using a mac mini late 2011 with an integrated Intel HD 3000 Graphics Card on OS X 10.9.3. Not the best I know but it worked pretty good with CS 6 and CC. I've deleted my Preference File without any success. Any chance to get it work again? The liquify tool itself works as expected.
