Mac Mouse Fix 3.0.8 solves UI issues and more.

UI Issues

• Disabled the new design on macOS 26 Tahoe. Now the app will look and function like it did on macOS 15 Sequoia.
  • I did this because some of Apple’s redesigned UI elements still have issues. For example, the ‘-’ buttons on the ‘Buttons’ tab weren’t always clickable.
  • The UI may look a little outdated on macOS 26 Tahoe now. But it should be fully functional and polished just like before.
• Fixed a bug where the ‘Free days are over’ notification would get stuck in the top-right screen corner.
  • Thanks to Sashpuri and others for reporting it!

UI Polish

• Disabled the green traffic light button in the main Mac Mouse Fix window.
  • The button didn’t do anything, since the window cannot be resized manually.
• Fixed an issue where some of the horizontal lines in the table on the ‘Buttons’ tab were too dark under macOS 26 Tahoe.
• Fixed a bug where the “Primary Mouse Button can’t be used” message on the ‘Buttons’ tab would sometimes be cut off under macOS 26 Tahoe.
• Fixed a typo in the German interface. Courtesy of GitHub user i-am-the-slime. Thanks!
• Solved an issue where the MMF window would sometimes briefly flash at the wrong size when opening the window on macOS 26 Tahoe.

Other Changes

• Improved behavior when trying to enable Mac Mouse Fix while multiple instances of Mac Mouse Fix are running on the computer.
  • Mac Mouse Fix will now try to disable the other instance of Mac Mouse Fix more diligently.
  • This may improve edge cases where Mac Mouse Fix could not be enabled.
• Under-the-hood changes and cleanup.
