iScreensaver has been updated to version

iScreensaver version 6.8.3 fixes an issue that could cause screensaver installers to crash silently on macOS non-English language systems (such as Korean). It also has improved error reporting, and has been tested with the latest versions of Windows 11 and macOS 12.1 Monterey. Any authors distributing screensavers to non-English macOS users should update and rebuild as soon as possible, and other authors are encouraged to update and rebuild when convenient.

Release Notes
We are pleased to announce the release of iScreensaver version 6 which supports macOS 10.11 (El Capitan) through 11 (Big Sur) and Windows 7 through 10. Read about Version 6

[Solved] Security Update 2020-005 breaks swift-based screensavers

It appears that Security Update 2020-005 is causing trouble with Screen Savers which are built using the Swift Runtime, which includes screensavers built with iScreensaver, as well as others.

Symptoms: after updating to Security Update 2020-005 on macOS 10.14 Mojave:

  • Swift-built screensavers no longer funcion
  • You will get a blank screen when the screensaver activates the first time.
  • After the first time, the screensaver will revert to the default macOS screensaver
  • Attempts to view the screensaver in System Preferences / Desktop & Screen Saver will give a blank page
  • Crash logs indicate that the process is crashing

We are investigating the issue and hope to have more soon.

In the mean time, if you are using any swift-based screensavers on macOS and want to run the 2020-005 Security Update, we recommend you temporarily switch back to one of the default macOS screensavers until this issue is resolved.

Alternatively, you could delay installing Security Update 2020-005, but it's generally not a good idea to skip security updates like this.
