I really don't like the sand dunes image when I start up/log in to my Mac.

Is there any way of getting rid of it or hiding it? I have a great desktop photo and I'd be happy to see this from the start, or even a black screen but not those depressing sand dunes.

I'd appreciate any help. (I tried to post on Apple's own forum but they won't let me post this message/content...which is odd)

Thanks

Matt

Turn off FileVault, then change the wallpaper, then turn FileVault back on (it should keep your custom wallpaper, at least it did on High Sierra).

There's a bug that always displays this wallpaper when the system is booted. I've posted before on the topic of this bug: MacOS Mojave - Brief Black Screen after Login. There is currently nothing that can be done about it, Apple needs to patch it in the next update.
is it a bug? seems apple's done this with intent; black screen behind the apple, followed by the mojave image under login; once you select your name, you see your chosen wallpaper. at least, that's what happens on my 2 macs...

EDIT: i DON'T see the default mojave screen if i disable the guest user, so this seems to be a solution.

EDIT2: there's a reason to keep the guest user account active (from apple's support pages):
Guest access works with the Find My Mac feature of iCloud to help you find your Mac if you lose it

Same problem here, I've seen plenty of people saying to change the "mojave.heic" file but it doesn't do anything... I'm trying to deactivate filevault, it'll take a couple of hours UGH. I'll see if I can fix it that way. But I don't want to have to deactivate and re-activate filevault EVERY time I change my wallpaper, because I do it A LOT.

UPDATE: removing and re-applying filevault works for me though I do think I'm going to be stuck with the image I took for now even if I change the wallpaper, at least it's much better than the dune. Anyways, many people have been having various problems with the lock screen, hope they fix this soon.

i've never used filevault, and the mountain is stll there; during bootup, when some messages show up ('system wasn't shut down correctly")... etc. apple wants it there (i don't, sigh)....

This worked for me (although it reverted back to the dunes with the 10.14.1 update):

Select image that matches screen resolution (2560 x 1600 in the case of 13” MPB).
Copy that image into /Library/Desktop Pictures.
RENAME existing mojave.heic to mojave.heic.backup.
RENAME
the image file you created to mojave.heic.
Log out and verify that’s the new login screen.

Works exactly as you said, I even deleted the mojave.heic which was more than 100mb big.

I change desktop backgrounds periodically. I right click on the photo and select "Set Desktop Picture" and I have that photo until I change it. Occasionally, if i have to restart for a software update the photo will revert to the Mojave picture, but changing it back is quick and painless. Maybe I am not understanding the issue here, or maybe i have not encountered the same problem.
