Desktop Background Changes Every Time I Turn Comp On

Hi,

Every time I turn my computer on, my desktop background changes to the default. I have OS X El Capitan, version 10.11.6. Any advice?

Thanks!

Hi,

Do you use more than one desktop / space?
If yes then you need to open the desktop preferences window on each space and make the changes while the window was on each,

Have you tried this? Go to System Preferences > Mission Control, uncheck "Displays have separate Spaces".

Restart your Mac and see how it works.

Thank you for the replies. I have only one computer and if I change my background and restart, I revert to the default Mac background still. Tried Jess's idea without success.
