um.... out of habit, i always delete all the apple wallpapers. i always use one of my own. but, having done that... i now have a black background when i boot up or log in (the login quickly changes to my current wallpaper).

can someone PM me, or upload the default wallpaper that's used for the boot wallpaper? and i promise not to delete it again....

I really don't know but if you go to the App Store you look for live wallpaper by squid melon it might be 99 cents I have been using it for years it will allow you to set the wallpaper that you like for desktop and login I use the metro theme it has a nice clock and date on my desktop

If should default to whatever wallpaper you are currently using on your profile. I always have my own wallpaper folder where I keep all of my custom wallpapers separate from the stock ones that come with the software and don't have this issue on the Mojave PB.

right, i have that. but, when i boot up, i now have a black screen; when i first installed mojave, it was the mountain image (one of them). once i get to the login window, i see my desktop background. isn't this what you're experiencing?

No on mine it goes straight from the Apple logo to the login screen with my wallpaper on the background.

From memory, macOS uses whatever background is set in the root account at the loginUI - although I don't know if this behaviour has changed with Mojave. Try enabling root and setting your background there

it seems... simpler. the boot image was a mountain; i deleted all the HD>Library>Desktop Picture files, and... the mountain's gone. just trying to figure out which image needs to be found...

hmm. Mojave default desktop background is NOT a mountain, but a sand dune.

The default system image is named Mojave Day.jpg
That appears to be the same used as default for the login window. Don't think it is the Mojave Night. and likely NOT the animated background Mojave (Dynamic). Pretty sure the login screen is the Mojave Day.jpg background.

Mojave_Day.jpg isn't working... can't (yet) figure it out. but a: i don't reboot often, and b: i'll keep at it. right now, my (unscientific) theory is... the image comes from the dynamic desktop image. will post back IF i resolve this.

thanx all!

I'm looking at the file right now - the name is not Mojave_Day.jpg - it's entered as Mojave Day.jpg, so a space rather than the underscore.
I don't see the login screen as using the dynamic image. I have not seen the login screen change through the day. Seems pointless if the default is using the dynamic image, yet not "using" it?

Isn't that correct that File vault enabled shows a black login background? I don't use File Vault, at the moment, so no way to check that.

even with the name correctly entered... my screen is black (when i get to login with my name, and guest); once i click on my name, i see my (blurred) wallpaper.

will live with it for now (a lesson to, at least, back up system stuff before i delete!)

I guess I am the opposite of you. I accumulate background pictures. I have some from 2000, I think. Probably about 10 years ago, I started merging OS X default sets from OS X 10.2 (Jaguar) and later into one folder, and copied that folder to the various Macs that I have - kind of a worthless hobby, when I look back :D I probably keep ~ 500 pix in that folder.

Why not just re-install OS on top of what's already there? Will get the correct images back, plists, db files, etc related with wallpapers, while preserving your settings.

because of some of the other things i've done (for example, replaced the location menu icon with a blank one, etc etc)...
and it's not urgent.

I don't know if you know that in the CoreServices system folder there's an alias to the Default desktop wallpaper - so I assume just by creating an Alias to the Mojave Day desktop wallpaper inside the CoreServices folder you'll have the login image back - on High Sierra choosing Show Original it highlights the "High Sierra.jpg" wallpaper. Call the alias "DefaultDesktop.jpg"

good idea. did not work. i tried several things: pointing the alias in core services to the 'correct' image in desktop pictures. making an alias of 'DefaultDesktop' and putting it in coreservices. removing the 'DefaultDesktop.heic' alias already there.

am spending way too much time on this, and will (now happily) enjoy the black login screen; once i click on my name, all is well.... thank u!

Check "reduce transparency" isn't checked in the accessibility settings. Happened on its own to me when my login background changed to a solid colour.
