Screensaver not working on Multi Monitor after macOS 13.3
With the roll-out of the macOS 13.3, numerous users have voiced their concern that the screensaver are no longer working along the expected lines on the multi monitor. According to them, if they have a dual monitor setup and when the screensaver starts, then the content of the main screen will show on the second screen and the content of the second screen will be missing altogether.
This issue could be reproduced across numerous third-party screensavers and a few built-in ones as well [such as the “Message” screensaver]. What is even more concerning to note is the fact that the bug was first reported when the update was in the beta stage, but unfortunately, it wasn’t addressed, and as a result of which, we have to deal with it in the stable stage as well.
To reproduce this bug, you just need to go to System Settings > Screensaver > select Message and hit Preview. The expected behavior [in a bug-free environment] should be that the screen saver should run on both monitors. But the actual buggy behavior is that the screensaver is only running on the second monitor.
As far as the official stance on this matter is concerned, the developers are aware of this issue, but they haven’t given out any ETA for the rollout of a fix. As and when that happens, we will update this guide accordingly. In the meantime, you could share in your valuable opinions about this discussion in the comments section below.
