This issue has been fixed in the 9/14/17 update. Thanks for your patience!
We're currently investigating an issue where users will have to double-click through menus and selections when a single-click should work. So far, this issue seems to be specific to Mac, but we haven't found any other common factors yet.
You can currently workaround this issue by following these steps:
- Launch Zwift, log in, go past the pairing screen, and join the game.
- If necessary, set your screen mode to windowed by clicking the Exit Full Screen button in the top-left corner of the window.
- Once you've changed Zwift to windowed mode, click outside of Zwift to a different window/program.
- Click back to Zwift.
- You should now only have to single click to confirm selections in Zwift.
Anytime you notice you're having to double-click through menu selections, you can repeat this process to workaround the bug.
