When applying transformations, editing text, and other actions, the "share" button is covering "accept" button (checkmark) to commit the changes. I can still accept changes (most times) by pressing the enter key on the numpad (except on laptop, where this isn't an option). Please don't tell me to reset my preferences, update, or reinstall, I've already tried that!
You didn't share a screen shot or give monitor details, so I'm guessing. One recent user post the same issue and it turned out he had a small monitor. If you have a large monitor with PS resized to take up half the screen, it's the same thing. The solution that worked for him was to select to use the Narrow Options Bar in Preferences > Interface (Photoshop menu). You will see icons instead of words, but everything will be there. https://photoshoptrainingchannel.com/tips/enable-narrow-options-bar-small-display/
On your Mac the return key does the same thing as enter.
Not always, Jeff, but sometimes. 🙂
On a Mac, "Return" is a carriage return (as it is called on a typewriter), and will start a new line. "Enter" is on the numeric keypad and has been known as the Action key, sort of an "Okay" button. Return and Enter keys have two different ASCII codes (36 and 76).
Several Adobe apps assign the two keys to different functions on both Mac and Windows. One example is: Return/Alphabetic Enter starts a new paragraph in InDesign while Enter/Numeric Enter is the shortcut for a column break.
