Hello plblily,

Thanks for reaching out out to Apple Support Communities. We see you have some questions about your desktop, and pops ups, and we'd like to help. Let's look into a few things, with each issue you're seeing.

With your display, as you're seeing jumping, and all other sorts of issues, have you tried restarting, to see if that helps? Shutdown or Restart your Mac

Restart your Mac

* On your Mac, choose Apple menu  > Restart.

* If you don’t want app windows that are open to reopen when your Mac restarts, deselect “Reopen windows when logging back in.”

This can sometimes help clear up display issues. If you still notice this happening, let's try isolating this by booting your Mac up in safe mode: Start up your Mac in safe mode

You also mentioned seeing unwanted pop-ups on your Mac, and the steps in the following link may be able to assist with this: Block pop-up ads and windows in Safari

Let us know if any of these steps help, and we'll go from there.

Regards.

My Mac started up in safe mode and screen/mouse work fine now. What do I need to do next to see what the problem was?
