Hi everyone,

Has anyone run into a screensaver issue on macOS 15 after enforcing the CIS Level 1 benchmark with Jamf Pro?

When the screen locks (either manually or from inactivity), the background just turns black, and the configured screensaver doesn't start.

If anyone has seen this or knows of a fix, any guidance would be greatly appreciated.

Thanks!

This is due to the “Disable Login to Other User's Active and Locked Sessions” (5.7)

You can fix this and restore the screensaver and ability to unlock with Touch ID by running:

/usr/bin/sudo /usr/bin/defaults write /Library/Preferences/com.apple.loginwindow screenUnlockMode -int 1

You can also apply that setting with a config profile. Jamf Compliance Benchmarks generates the config profile for you. Jamf Compliance Editor might generate the config profile, but I haven’t personally tried that.
