You’ve found a Mac wallpaper – or desktop background – that you L-O-V-E, but the Mac’s having none of it. Every time you switch the Mac back on after powering down, the wallpaper has gone back to the default setting. If your Mac wallpaper keeps resetting, here’s how to make it stop.
This problem seems to afflict Mac users who are using an external display with a MacBook. The solution, which I found on one of the Apple support forums, requires some jiggery-pokery (technical term) with the display cable. Here goes.
How to stop the Mac wallpaper from resetting
- Make sure you’ve got the laptop and external screen switched on, with the laptop lid open and screen on
- Physically disconnect the external display by pulling its cable out of the Mac
- Reselect your chosen wallpaper from System Preferences
- Shut down the Mac
- Restart the Mac without the external screen connected
- Once you’ve logged in and reached the desktop, re-connect the external display
The next time you restart the Mac, your chosen wallpaper should remain in place.
If this works for you (as it did for me), let us know on the comments below.
This worked for me, thank you!
This works ONLY when I disconnect the external monitor everytime before turning MacBook back on. Meaning, when MacBook is restarted WITH the monitor connected, it erases the settings and goes back to default wallpaper, for some reason. The only way to go around this trouble is to turn off MacBook and disconnect the monitor, and reconnect it when the computer is fully on. VERY ANNOYING. I mean, it’s Apple and MacBook. How can something so simple turn out to be such a mess? WHY CAN’T I JUST SET THE WALLPAPERS FOR BOTH SCREENS AND LEAVE IT AT THAT? I want to set my wallpapers for both screens only for once and just leave the monitor connected, turn off and on without this stupid problem. If someone have a solution for this, please please let me know.
