iScreensaver and macOS 10.15 Catalina (Beta versions)

macOS 10.15 Catalina is scheduled to be released this fall. At the present time, only a developer's beta is available and is under NDA. We are investigating compatibility.

Please note that others have reported that the first developer's beta of Catalina is "definitely rough and not just for screensavers. Roughest macOS initial beta in years..." and "...wait for Catalina beta 2".

See for a discussion of another macOS screensaver having trouble in Catalina (this has nothing to do with iScreensaver, but is just an example of the general screensaver problems in Catalina Developer Beta 1).

We'll be posting information in this discussion thread as it develops.

    Update: we have just released iScreensaver 6.1 which offers support for macOS Catalina. Although Catalina is still in beta, we feel comfortable recommending that all authors start using 6.1 in preparation for the official release of Catalina, expected in the Fall of 2019.

    There are only a few small issues remaining with Catalina, please see the Release Notes for a discussion.

  • Update: we have tested against today's release of Catalina (19a546d, Developer Beta 7 / Public Beta ) and are seeing good results.

  • Update: we have tested against yesterday's release of Catalina (19a558d, Developer Beta 8 / Public Beta ) and are seeing good results.

  • Update: we have tested against the latest release of Catalina (19a578c, Develoepr Beta 10) and are not seeing any new problems.
