Image distortion via Change Desktop Background?

A couple of months ago, I was searching through my iPhoto gallery looking for a picture to set as my "new" desktop background. As I changed from one background to another, the over-all display from my MBPR (MacBook Pro Retina) exhibited distortion. I do not know how to explain the effect any further, but I went to my nearest Apple Store yesterday, and I was told by a genius that it may simply be a bug. He also ran several tests on my MBPR and found nothing out of the ordinary.. Has anyone else experienced this phenomenon?

Hello
What kind of image file you want to set as background? As far as I know not all picture formats work as desktop background.
You should try it with a JPEG picture. Such pictures always work properly.
Otherwise you must ask on a Microsoft forum. Here we can talk about Toshiba notebooks.

Wallpaper not showing up in "Change Desktop Background" window

I just noticed an odd issue today on my Mac Pro. When browsing the built-in wallpaper folders (Nature, Plants, etc) in the Change Desktop Background window they are empty. My "Pictures Folder" one shows all the images correctly as well as browsing the ones from iPhoto. (I also have Aperture 2.1.2 installed but no projects yet so that part is empty.)
I performed a permissions repair, checked that the actual files were there in /Library and removed the com.apple.desktop.plist pref's file. After doing that all the pictures showed up again UNTIL I browsed around the picture folders in the Change Desktop Background window then they stopped showing again.
Could something in my Pictures Folder be causing the issue? Any ideas?
Thanks,
-Jim

Thanks for clarifying. I don't do right or left click, but occasionally do CONTROL-click and doing that brings up the contextual menu item "change desktop background" which leads to the Desktop prefPane. Now, why you're having issues, I have no idea. However, I suggest creating a new admin user account, logging into it, and seeing if changing the desktop picture works there.

Change Desktop Background - Stretch Picture

I noted a strange thing when i right click and select Change Desktop Background, i once noted the option of whether to Stretch the picture. But now it is gone.
Does anyone know how do i enable it?

The option is only offered when it is actually needed, most likely your images don't need stretching.

HT2478 how do you make the setting to change desktop background every time you shut down your mac

how to make setting to change desktop background every time you close your mac
because i want to make it if anybody tries to change my dekstop picture i want it to go backto set desktop picture

Don't let other people access your Mac in admin mode - they might change something a lot more important than the Desktop picture.
However you can use Automator: create an Application in it, and select 'Set the Desktop Picture' from the Library. Choose the picture you want. Save the application, then go to System Preferences>Accounts>Login Items and select the Automator application you just created. This will then run at startup and set your chosen picture.

"Change desktop background" instantly hides when opened

I have a rather strange issue that's a nuisance. When I right click on the desktop and select "Change Desktop Background," the system preferences pane opens, but automatically is hidden (similar to if you press cmd+H). I have to click the icon to restore the window.
This does NOT occur if I first open System Preferences and then select "Desktop & Screen Saver," or if I open "DesktopScreenEffectsPref.prefpane" from quicksilver.
I have tried deleting com.apple.desktop.plist and restarting, but this did not solve my problem. I think I may have experienced this problem in Lion as well, but I currently experience it on Mountain Lion.
Any help is greatly appreciated.

This same thing happens to me, and while not the end of the world, it is defintely annoying. Have you figured it out? Thanks!

Change Desktop Background Broken 10.8

When I "2 finger (right click)" click on the desktop and select "Change Desktop Background", System Preferences comes up and I can change my background. I then close System Preferences and try it again and System Prefrences doesnt open. It will work the 1st time after a reboot, but not work anytime after.
Is anyone else having this issue?
Is there anyway to see what that command is doing on the context menu? "Change Desktop Background"

I'm having a similar problem after installing Mountain Lion on a new MBP Retina. Sorry I didn't see your post before I duplicated it (https://discussions.apple.com/thread/4217330?tstart=30).

Issue with desktop Opt/Click (right click) & 'Change Desktop Background'

I have an issue with the opt/click in the desktop in ML 10.8.2. The 'Change Desktop Background' using opt/click (right click) works after reboot, but fails to open (work correctly) thereafter. The 'System Preferences' icon bounces in the dock but nothing else happens, I have either click on the SP icon or re-opt/click (R click) again to get it working. All else seems to be in order but not this. I have tried this with 2 complete full installs & still doesn't work correctly (same issue. I have reported it to Apple, but I was wondering if anyone else experiencing this problem?

So, here's what I've learned so far.
Fresh reboot. Works fine. Close and try again, doesn't work. This you already know.
Here's what I tried to see if it makes a difference:
I removed:
~/Library/Caches
~/Library/Preferences/com.apple.finder.*, com.apple.systempreferences.* and com.apple.desktop.*
That didn't help.
I tried it in safe mode. Same issue.
Here's something interesting I noticed. If you open terminal and killall Finder, that refreshes it and makes it work again... for 1 try.
This does, in fact, seem like a bug.
For reference, I'm currently on a mid 2012 macbook pro. Running fully updated on mt lion.

Changing desktop background issue12

hi, I have an issue with my macbook pro retina display 13" running mountaion lion os.
I was trying to change my desktop background, so I right-clicked my mouse and choose 'change desktop background option'. The first time I did this, nothing happened (however i noticed that the 'system preferences' icon on my dock was bouncing after I did that). When I tried to do the same thing again, it worked. I did this several times and I noticed it will only work on the second time. fyi I was not having this issue till today. Anyone else facing the same issue? Do I need to format my laptop or re-install my ios to remove this bug?
sorry for my bad English. Thanks!

hi! thanks for the reply.
I tried to follow the instructions, but I don't understand with the last instruction which says "Restart the computer and open System Preferences (or problem program) and reset all your preferences again"
I went to restart my computer (after deleting the com.apple.system...), and it doesnt solve the issue. However, I noticed that deleting the com.apple.system the "change desktop background" will work once. but if i close and do it the again, it wont work (same thing if i restart my laptop). I know i am just being anal about this small issue lol, but i noticed some other users experience the same thing as well as me.

thanks for the reply =) I will try to ask my friend whether he is having the same issue as me.

Cannot Change Desktop Background in Windows 8 Installed Via Bootcamp

I've been running parelells, but decided today to just go the boot camp route and everything went through fine EXCEPT I cannot change the wall paper on the windows 8 desktop?
I select the new image in desktop background in personalization click save changes and the background stays the same...?
I don't get it.
And by the way, I am NOT new to windows or mac, been using both for a long time and was a systems administrator and bench for years, this is NOT a novice "how to" question...It's just not working?
Anyone else seen this before?

are you using an activated version of win 8? you cant personalise win desktop otherwise.

Cannot change Desktop Background image

When I go to change my Desktop Background, it will try and load up the pictures in my Pictures folder (but no subfolders). I can switch my background to one of these images, even though the "Loading" progress bar is still visible.
Here is the odd thing, however. If I click on any of the other types of images (Apple Images, nature, Plants, Black & White, Abstract, and Solid Colors), nothing appears. I jumped over to another user on the same computer, and those images populated properly. Any ideas on what is going wrong? Why can't I change my background image? I've had this problem with both Mac OS 10.5.0 and 10.5.1.

I managed to fix this problem.
I did verify and repair permissions just for kicks. Not sure if that helped or not, but I did it anyway.
Then I went back into the System Pref pane, and clicked on Apple Images, then clicked on the Change Picture checkbox. While none of the images appear in the white box, my background did change to one of the Apple Images (such as the black and purple Leopard-only background). I then closed System Preferences, opened it back up, and the images loaded up properly this time!

How to change desktop background in AppleScript in 10.7?

I'm just now upgrading from 10.6 to 10.7, and I'm having trouble with a script that I wrote that worked fine under 10.6. In part, it executes the following command:
     osascript -e "tell application \"Finder\" to set destop picture to POSIX file \"<path>\""
to change the desktop background image to one of two different files based on other conditions.
In 10.7, this command completes with no error code, but it only changes the background of one of my four desktops. Is there a way to programmatically change the background image of all of my desktops simultaneously? Failing that, is there a way to a) find out how many desktops I have and b) loop through them, setting each of their backgrounds in turn?
I did search the web and found the following suggestion:
     osascript -e "tell application \"System Events\" to set picture of every desktop to \"<path>\""
Unfortunately, that also changes only the current desktop's picture.
The larger script is in Perl, so I'd prefer a technology that works well with that language, but if I have to change to a different scripting language, that's not the end of the world.
Thanks much for any suggestions!
Richard

Actually, “repeat with k from 18 to (18 + N - 1)” was not a good idea, since it works only with N < 5, as I discovered after posting the script.
So here's an improved version of the previous script that should work with any number of desktops:
set theFile to POSIX file "/Library/Desktop Pictures/Isles.jpg" -- just an example
-- Find out how many desktops you have:
tell application "System Preferences"
    reveal anchor "shortcutsTab" of pane id "com.apple.preference.keyboard"
    tell application "System Events" to tell window "Keyboard" of process "System Preferences"
        set N to count (UI elements of rows of outline 1 of scroll area 2 of splitter group 1 of tab group 1 whose name begins with "Switch to Desktop")
    end tell
    quit
end tell
-- Loop through the desktops, setting each of their backgrounds in turn:
tell application "System Events" to key code 18 using {control down} -- Desktop 1
tell application "Finder" to set desktop picture to theFile
repeat (N - 1) times
    delay 1
    tell application "System Events" to key code 124 using {control down} -- ⌘→
    delay 1
    tell application "Finder" to set desktop picture to theFile
end repeat

Change Desktop background from another account ?

Hi Guys,
Just wondering if it's possible to change a desktop background from another account on the same machine.
I'm running 10.6.8, and there's no particular reason for doing this at present, but we do have a couple of work machines where the user has been restricted from making changes to the machine, and it'd be easier to do this from the administrator account.
Also, is it possible to change a desktop background via Apple's remote desktop?
Thanx in advance.

This same thing happens to me, and while not the end of the world, it is defintely annoying. Have you figured it out? Thanks!

Cannot change desktop background...

This is a problem that has been annoying me for about a month now... i set my desktop background as an iphoto image, and went to change it a few weeks later but it wouldn't let me! the small image of the desktop appears in system preferences, but the background will not change.
if anyone knows how to fix this, your help will be appreciated...

Confounding!
Log back into your problem account:
Here's the whole litany for thoroughly checking your home folder. It's not as daunting as it looks.
1. Navigate to ~(YourHome/Library/Fonts - drag this folder to the desktop.
• Restart and test your applications.
• If they work start adding the fonts back few at a time.
( Likely suspects are Times RO, Helvetica Fractions and Times Phonetic, also if you do not use Classic you can trash the classic fonts.) If not, put your Fonts folder back.
2. Check Preferences Thoroughly;
• Navigate to ~(YourHome/Library/Preferences drag this folder to the desktop.
• Restart and test your applications.
• If this works, save the old preferences folder somewhere else or on disk, name it "old prefs" .
** Note: A very important file is the "com.apple.Mail.plist" preference file located in the Preferences folder which contains all email account settings and general mail preferences (hold this one and replace if your problem is not with Mail).
You'll have to go through some of your System Preferences and apps to set the preferences back to how you like them. (Or if you have the time and inclination, "cherry pick" through until you find the problem one or two.)
3. Check Permissions Inside Home Folder
• Navigate to YourHome/Library.
• Get Info (Command - i) on folders for apps you are having problems with.
• Open the "Ownership & permissions" disclosure triangle.
• Make sure you are the owner, with "read and write" access.
• Click on "apply to all"
• If this is correct, open the "Applications Support" folder and do the same procedure (Command+I) for the folders with the names of the applications you are having trouble with.
(Note:The reason to check this is because repairing permissions with Disk Utility doesn't touch permissions inside your home folder.)
4. Navigate to YourHome/Library/Caches and drag this folder to the trash, then log out and back or restart. There is no need to replace this folder.

Cannot change desktop background picture to my own photos

Hi, in desktop & screen saver I cannot change the desktop background image to any of my own (iphoto) pictures, it shows the list of the images and thumbnails but will only change the pic to the 'Apple' ones (nature,plants,black & white, abstract), if I select any of my photos under 'iphoto albums' the desktop image simply turns light blue.

Hi.
I'm seeing what seems to be the exact same problem you described. Were you able to figure it out and fix it? I don't see a solution posted.
Thanks.

Mac laptop screen going to sleep and changing desktop background

last weekend my daughter called to say that her Macbook was acting strange. On Friday night she saw the battery icon said 25%, so she shut the system down. The next morning she plugged it in and booted. It took a while and the desktop background had changed to something grey. Also, the screen would blank out after 30 seconds to a minute. If she hit the space bar it would show and then go black after the 30 to 60 second time period. I had her shutdown and boot to her external drive where she had a month old image of her system. It took a minute or two to boot (it always seems like a long time when you are on the phone). It came up as her normal system and background. She left it for over an hour and it did not black out or go to sleep. We were planning on doing a restore the next day, but when she did a normal boot later that day from the internal hard drive, it came up with her normal background and the screen stayed active. She had not tried to set any settings. Is there something that a low battery would do to change the energy settings? We were going to explore the settings when the system magically worked as normal. It seems strange that a boot to the external drive would restore settings so that the system worked normally.

Energy Saver and third party USB often don't go well hand in hand. I would though contact OWC and let them know you are having this problem, since they have a good track record of supporting the Mac platform. In the meantime, use Screen Saver instead of Energy Saver.
And always keep your data backed up at least twice as my FAQ explains:
