screen saver not getting activated

Hi rev148,

Without further details it's difficult to offer specific suggestions for your concern. As a starting point visit Use a screen saver on your Mac and ensure that the screen saver is enabled and configured properly. Then, if necessary, try one of these options for activating it:

"Start or stop the screen saver on your Mac

• The screen saver automatically starts whenever your Mac sits idle for the amount of time you choose in Screen Saver settings.
• To change how long your Mac can be inactive before the screen saver starts, choose Apple menu  > System Settings, then click Lock Screen  in the sidebar and choose settings on the right. (You may need to scroll down.) See Change Lock Screen settings.
• If you set up a hot corner for the screen saver, move the pointer over the corner to immediately start the screen saver. See Use hot corners.
• To stop the screen saver and show the desktop, press any key, move the mouse, or touch the trackpad."

If those don't work or if one of those options is missing, reply with additional details regarding what you're seeing instead as well as any other relevant details to the screensaver for your Mac. You may also try these options in safe mode following How to use safe mode on your Mac to rule out possible software complications.
