I cannot change my lockscreen background!

Everytime I turn on my computer, the background I wish to use is gone and replaced with the standard Catalina image. Does it happen on every mac or is it just a few ones? And how can I fix it? Thanks for the attention!


MacBook Pro 13", macOS 10.15

If you mean every time you boot your computer from a dead stop— then no you can not change the lock screen. You have not booted into your user account at this point and you are seeing a preboot screen.


The preboot partition contains the code which handles the login for an encrypted drive, after that is successfully unlocked it is handed off to the main OS.


When you have an encrypted boot volume you receive a log-in screen before the main OS boots, you have to authenticate that in order for the encryption key for the boot volume to be released.
