iScreensaver has been updated to version

iScreensaver version 6.8.4 has a number of bug-fixes and improvements, including several bugs that could cause playback failure on multi-monitor macOS Apple Silicon / M1 systems or the macOS Ventura 13.0 beta. Authors who are building screensavers that may be encountering any of these issues should update, re-build, and re-distribute their screensavers.

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.
