Q: Desktop Wallpaper keeps going back to the standard wallpaper after reboot

Hi,

I posted a similar thread since I'm having the same proble.

I tried what you suggested and it seems to solve the problem ONLY when I log-out then log-in again WITHOUT rebooting. If I change the wallpaper after entering the terminal command you mentioned and reboot straight away (without loging-out first), the wallpaper reverts to the previuous one.

It seems like the log-in window has something to do with retaining the last wallpaper I choose (not sure how).

Thanks anyways!

softwater thank you for your post, this just happend to me and your terminal command below worked perfectly for me.

Thank you

Apple please fix this.

=============================

Open Terminal (Applications/Utilities/Terminal.app) and paste this command

rm ~/Library/Preferences/com.apple.Desktop.plist

this did the trick for me, thanks!

PLEASE, NEED HELP. I did that new archive called autodiskmount.plis that Ahmed21788 said  https://discussions.apple.com/people/Ahmed21788

and now my Mou tain Lion Retin Mac Book DOESN'T START. Even on safe mode. I've got lots of works inside it and can do nothing. I'm really in PANIC.

hey mate... sry but this has worked totally fine for me, no issue's at all.. and i thnk the steps what i mentioned shud'nt stop ur mac frm booting up

i am not sure what you did or missed out on..

i will upload a video later this week on youtube and post link & hope that it explains..

dont panic mate, ur stuff is safe unless u format ur hdd..

let me knw if u need help in gettn ur mac start up.

Worked Perfect! Finally!! Thank You!

I had to restart twice for it to start working, but it did fix this issue.

MBPR came with ML installed and I had this same issue of my wallpaper cycling through the default desktop backgrounds, a differnt default backgorund would greet me everytime I booted up.

Thanks Softwater! Big help!

Thank very much it works and its very easy way

i tried this and it resulted in my mac not booting up. It gets stuck at the logo n spinning progress bar. None of the safe mode methods are working either. Im in a fix. Cant believe something can go so wrong just trying to set a **** wallpaper!

the exact same thing has happened to me

did u find a solution? Would really appreciate it. Thanks.

ok anyone who had the same problem as GuilleMostaza and I (ie their mac refused to boot after making changes suggested by Ahmed21788) can try this

boot your Mac into Single User Mode by holding "command-S" on startup and wait for the prompt. enter

/sbin/mount -uw /

then

cd Library/Preferences/SystemConfiguration; ls

then when you are in the directory where the autodiskmount.plist is you can remove it by entering

sudo rm autodiskmount.plist

and type in your password.

then type "reboot" and hopefully your Mac will boot!

So simple, but the easiest fix by far as I couldnt get the others to work.  Cheers

This worked for me.

Like others, I'd had this difficulty & found the thread useful.

That said, I preferred to find the plist file manually, so I knew where I was deleting it from, rather than just typing something in. (Also would make sure I'd not do any typos!)

For those wondering, it was in the user's library folder, rather than the general library folder. There was also a 'lockfile' - which I assume was because it was running -  I didn't bother to delete that & it worked fine.

Looking at earlier posts referring to which HD Mountain Lion and the image are both on, I'm guessing mine got confused as Mountain Lion is on the New computer & I used migration assistant to move all the files & software & settings etc. from an older machine (running Lion).

(My biggest problem was remembering which image folder my image was in!)

SOFTWARER UR THE BEST :D:D:D:D:D:D:D:D
