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.
iScreensaver, macOS Big Sur 11.5 and Montery 12.0 Compatibility Issues
We have identified some issues that arise which can prevent screensavers and the editor software (Designer) from working if a user upgrades to macOS Big Sur 11.5 or the beta version of Monterey (12.0).
We have found the problem and are working on a new version of iScreensaver Designer which will remedy these problems.
This will require that you re-build and re-distribute your screensavers.
We will have another annoucement soon.
