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

Is it possible to stop/interrupt a running screensaver WITHOUT user input?

edited December 2021 in Feature Requests

Been using screensaver for a while and absolutely love it.

We're building a that pops up a window for 10-20 seconds with caller id information.

App is done in Xcode/Swift. All works good except that the popup will not penetrate/cancel a running screen saver. Any screen saver, not just, so not a bug but perhaps a feature request question?

Since a window popup does not penetrate a screen saver is there any way to do that via a programmed command/trigger?

Any/all suggestions welcomed.

Merry Christmas


  • Interesting question, and I believe the answer depends on a few variables:

    • what version of macOS
    • whether the screen is locked at the time (the locked screen would require the user to authenticate with password or TouchID


    • Before macOS 10.13, the screensaver process was called ScreensaverEngine, and you could change any window level to be in front of the running screensaver.
    • In macOS 10.13 it moved locations (and became more tightly locked down, preventing you from putting an app in front of the screensaver level)
    • Under older versions of macOS, an app (that had sufficient permissions) could kill the screensaver, but this may no longer be possible
    • Starting with 10.14, the new process is called legacyScreensaver, but I don't think your app can easily kill it

    Modern macOS uses the notification center, and I believe that notifications can show up even while the screen is locked, with the proper user choices:

  • Thank you very much for your comments. Food for thought :)

    Running Monterey. Don't want to go backwards so Notifications may be the solution. Thanks again.
