This message is on the screen every morning when I turn back to the desk.
It's not possible to click on it and I have to reboot the machine.
It appeared after I update to High Sierra 13.6, and disappeared after I updated the MacBook to Mojave.
My iMac being a bit old it can not update to Mojave.
Does anyone have an idea on how to solve the problem.
iMac, macOS High Sierra (10.13.6)
As the text above mentions, if the issue doesn't happen in safe mode but happens again when you restart into normal mode, the steps in the article If you think you have incompatible login items will likely help:What is safe mode?
Safe mode (sometimes called safe boot) is a way to start up your Mac so that it performs certain checks and prevents some software from automatically loading or opening. Starting your Mac in safe mode does the following:
- Verifies your startup disk and attempts to repair directory issues, if needed
- Loads only required kernel extensions
- Prevents startup items and login items from opening automatically
- Disables user-installed fonts
- Deletes font caches, kernel cache, and other system cache files
If your Mac has an issue that goes away when you start up in safe mode, you might be able to isolate the cause.
Start up in safe mode
To start up in safe mode:
- Start or restart your Mac, then immediately press and hold the Shift key. The Apple logo appears on your display. If you don't see the Apple logo, learn what to do.
- Release the Shift key when you see the login window. If your startup disk is encrypted with FileVault, you might be asked to log in twice: once to unlock the startup disk, and again to log in to the Finder.
To leave safe mode, restart your Mac without pressing any keys during startup.
If an issue doesn't happen in safe mode
If an issue doesn't happen when your Mac is started in safe mode, try restarting without pressing any keys.
- If the issue comes back, you might have incompatible login items.
- If the issue doesn't come back, it was probably caused by a cache or directory issue with your startup disk, which safe mode fixed.
I hope the information I've provided helps.Test your login items
Choose Apple menu > System Preferences, then click Users & Groups.
Click your account name below Current User, then click Login Items at the top of the window.
Make a list of the login items—you’ll need to remember them later.
Select all of the login items, then click the Remove button
.
Choose Apple menu > Restart.
If this solves the problem, open Users & Groups preferences again, add the login items one at a time, and restart your Mac after adding each one.
When the problem occurs again, follow the steps above to remove only the last login item you added.

Hi CarlosP1228,
I haven't created another user account but will do so and leave the Mac on and unattended for a while and see what's happen.
I have disabled the screen savers. The tab at the bottom left of the prefs panel is on "never" and still the problem occurs. According to the text in these windows, it doesn't make sense!
Hi CarlosP1228,
Sorry for the delay, but I went through all the steps you described above and that problem is still present.
Any idea?
Thanks in advance
You can’t open the application ”ScreenSaverEngine.app” because it’s not responding
