This is what happened:

  • My desktop background changed 3 times at different times.

The change picture (every x time) option is disabled and I have always had it in that way.

  • When I selected a picture to be open, two more pictures were opened too.

I perfectly remember that I only choose one picture to be open. As a matter of fact, this event had never happened to me in my life. Also, think about this, what a "coincidence" that the same day that pictures are opened without requesting is the same day that my desktop background changes too.

There must be a reason because things don't happen just like that.


  1. All the time when this happened, my mac didn't have connection to internet.

  2. Every once in a while I see a message on the upper RHS (in the corner of the screen) telling me that I should update something related to the system but I always click on later and then the message vanishes.

  3. User Allan said that I am not hacked, then what could possibly have happened?

Please tell me.

I think there must be a reason because things don't happen just like that.

  • @nohillside but notice the note on the close box "If this question doesn’t resolve your question, ask a new one." And that's what I did

  • If you were not connected to the Internet at the time, how could you have possibly been hacked? You can’t have a hacker connected to your computer while your computer is offline

Do you have the same image selected for all Spaces? that would be the simplest explanation, that you don't.

Test by pressing F4 [or FnF4 depending on how your machine prefs are set]. This should zoom all the windows out so you can see them all, but also present a set of you current Spaces at the top of the screen.

If you mouse over those, they will expand to small pictures & unless an app is covering the entire Space, you will be able to see the desktop background for that Space too…

For example…

enter image description here

All my Spaces are set to the same image, but it's not compulsory.

  • The answer to your question is Yes. The same image for all the Spaces

  • Actually I usually work in one Space. And when adding another Space, it automatically set the same desktop background to the new Space
