mission control - how do I change all my wallpapers

So Lion gives me the chance to have separate wallpapers per "space" or whatever we're calling them now. However, I don't really want to and the idea of changing 9 spaces wallpapers one at a time seems like a retrograde step not a move forward. Is there any way to change all of them at once?

MacBook, Mac OS X (10.7)

It is actually very easy to change all of the desktops at once to do that go to desktop 1 and change the wallpaper after that all futere desktops created will match the wallpaper of desktop one. With the exception of the desktops already created. You will have to change them manually. But if you just change desktop 1 (the main desktop) all future desktops will be the same. Hope this helped.

I'd like to know this, too. Right now I have a million spaces with different wallpapers so I don't want to get it right and then have to change them all again, but try the wallpaper page in system preferences. I've changed my wallpapers in each space by option-clicking the image in Finder and clicking "set as desktop image" or whatever it says. Setting wallpapers in System Preferences may change it for all spaces.

Setting wallpapers in System Preferences doesn't seem to do it--the wallpaper is only changed for the particular desktop you're in when viewing the System Preferences.


It would be nice if there was a choice to either change the wallpaper on the particular desktop you're viewing, OR to set across all desktops.


Does anyone know a fix?

While playing around with the desktops last night I "discovered" that each desktop can have their own wallpaper and also change it at different time intervals, which is kind of cool, I guess. I dont know if each desktop can be set to have a particular screensaver, so that a different screensaver kicks in depending on which desktop you went idle on. Anyone else seeing their wallpaper default back to the new Lion nebula background on restart?

Honestly it isn't that hard. It should only take about 30 seconds in general. Jus click 9 x's, change the background, and then 9 plus symbols. If you do it when your machine starts up, you don't even need to worry about having to replace all your windows and stuff (unless you are using resume). I understand it may be a tad tedius but I don't really think this is a bug.

Well earned name there applefandan. I don't consider this to be a new exciting feature, it's adding something that people didn't know they wanted to do (different wallpaper per desktop) at the expense of something they used. It's certainly not as extreme as the aerial "feature" on the iphone4 but it's an example where people forget that things actually get used.

The suggested workaround of deleting all the desktops except for #1 and adding them back in after you change the background also causes another problem for those of us who have pinned applications to specific windows. You lose all those assignments so that everything is pinned to the #1 desktop. That's way too much work as I have a lot of pinned applications to specific desktops.


We need an "apply background to all desktops" option, that would do the trick.

To me its also like a downgrade feature.

But well, I use a workaround for this:


Since I need with every wallpaper certain areas for my GeekTool stuff I started to use one .psd file as wallpaper.

http://dl.dropbox.com/u/5905196/Screenshots/screen1.png

So whenever I want to change the wallpaper I just open the psd file and change the one layer.

By doing that the OS wallpaper is always the same: the psd file.

All I have to do after the in-file-change is lock the screen and log in again and all my spaces have the new background.


I guess this should work with every other image file also if you put your wallpapers always on the same spot with the same name and file extension.


Works fine for me.. at least better than changing the wallpaper for 8 spaces or deleting my spacing and setting them up again and assign all the apps to the spaces over and over..

Thanks roxtii, your workaround works. I do one thing different though, instead of logging out and back in to force the desktop to refresh to the changes made to the wallpaper image, I just use the Killall Dock terminal command.


Too bad we have to resort to such work arounds to solve a problem created by a change in OS X Lion. This and a few other things in Lion are not enough to force me back to Snow Leopard, but just enough to aggravate my user experience.
