I’m linking to this because I’ve been stung by the problem too. The issue is with new MacBooks and MacBook Pros with the button-less trackpad. These trackpads have no dead zone like the old trackpads did. So until I get accustomed to using them, I often end up resting my right thumb on the lower portion of the trackpad where the physical button used to be. Because of this, once I go to move the cursor with the trackpad, I inadvertently perform a two-finger gesture, which Apple now recognizes on these new trackpads. Photoshop interprets these as either zoom or rotate actions, which is rarely what I want to happen. This plugin disables those actions in Photoshop, until Adobe engineers figure a graceful way to interpret (or otherwise ignore) two-finger gestures.
