Did you find a solution to this? I am new to app development. I am trying to make an app that will assist in making proper videos and screenshots for submission to the App Store. They images must be a certain size, it isnt easy to just drag a window to be 1200x400, and not 1201x399 for example. I want a simple menu item, that will resize a window to a preset size. It works using AX with no sandbox... I would love to sell the app on the App Store, although my primary motivation is to try to improve sales of my other app on the MacOS App Store. My App which I am very proud of, has sold 1 copy since going live on the App Store... I am not expecting Massive sales volume, as it is a niche product. I know people in my true industry (I am not an app developer) would love the app if they got a ahold of it.... I won't self promote it here, as it isnt the place, and either way it is unlikely someone reading this thread would have a use for that app... I think app developers may find this other app, with the same issue you are having, useful...maybe I can sell a few copies for a dollar. I also am not a marketing guy, so it makes this harder for me.
