macOS screensaver installer fails to launch on non English language system

We have identified an issue where a screensaver installer will fail to launch on macOS systems where the language is not English. For example, we are seeing this on Korean-language systems.

As a workaround, you can temporarily set the system language to English.

  1. Open System Preferences, and select Language & Region.
  2. Click the Plus (+) button, add English and drag it above your currently selected language, as shown here:

  1. Then, restart the computer, install the screensaver, then set the language back afterwards.

We are working on a fix and should have a new release shortly.

This issue has been fixed in the latest build ( or later): See Release Notes
