Desktop Background pic resetting every time I turn the computer on
I am using a 2022 M2 MacBook Air with a Pluggable UD-ULTC4K dock and 2 Dell Monitors.
Everything works OK. My only issue is that every time I turn my computer on, the pictures selected for desktop background would reset and get the default OS background instead. It's just annoying to reset all pics for each monitor every time. Is there a way to avoid this? |
Hello,
Please check the following article - How to prevent your Mac from changing the wallpaper after a restart Thank you. |

From my experience, when you set specific wallpapers for each monitor and you want them to retain, you'd need to shutdown your Mac. A reboot with the monitors attached won't suffice. You need to shutdown your Mac with your monitors attached. Now, from my experience what I described above works pretty much most of the time with "native" monitors, no DisplayLink monitors. The tricky part with DisplayLink is that it are software/virtual displays that carry a signal over a USB cable to a device that renders it. Typing this I realize it's probably not in the right terms but basically a DisplayLink screen is not running on your builtin video card. To remember settings you choose in macOS on different screens, macOS needs unique identifiers. EDID is a feature that provides this. Since DisplayLink works a bit differently, mostly in software when creating a virtual screen, there might be issues where a new unique identifier might be generated for a DisplayLink screen. Your macOS thinks it's a completely new screen while in fact your hardware is exactly the same. Now I'm no technician, but in my years of dealing with DisplayLink issues on various Mac devices this is what I believe going on.... |
