Login screen picture issue

i recently tried to change the login screen using
sudo defaults write /Library/Preferences/com.apple.loginwindow DesktopPicture 'pathtopicture.jpg'
yes, i changed the 'pathtopicture.jpg' part to the location where the picture was located. for whatever reason it didnt work and now im stuck with a blank blue screen. how do i restore the picture? please help.

Perhaps your path to picture was invalid. That would force a simple blue screen. Put in the path for the normal background:
defaults write /Library/Preferences/com.apple.loginwindow DesktopPicture '/Library/Desktop\ Pictures/DefaultDesktop.jpg'
or
defaults write /Library/Preferences/com.apple.loginwindow DesktopPicture '/Library/Desktop\ Pictures/Nature/Aurora.jpg'
Also, you may be able to delete the attribute and it may just revert to the defaultdesktop (but I'm not sure):
defaults delete /Library/Preferences/com.apple.loginwindow DesktopPicture

  • Blank Login screen - DNS issue

    At my company's site we seem to be experiencing an intermittant blank login screen but only for the microsoft sign in page, the Skype sign in page loads up fine.
    When skype loads up we get this screen:
    And the users choose "Microsoft account". They should then see this screen:
    Instead they get this:
    At the bottom there is a warning message saying the following:
    "This page contains errors. Go back"
    The site is using OpenDNS to filter DNS queries for the PCS and the policy is fairly locked down.
    On any affected PC, if I:
    - Close Skype
    - Point the DNS settings to something like 8.8.8.8 (google's DNS server)
    - Load up skype
    The login screen (image 2) loads up normally. The user can login and I can then flip back the DNS settings to the OpenDNS server and there are no further issues.
    What this means is that Skype is trying to contact a Microsoft/Skype server somewhere on the interent and because it is not on my OpenDNS whitelist it gets blocked and fails like in image 3.
    My question is can anyone tell me what the server is? I went through the OpenDNS logs and whitelisted a bunch of microsoft stuff and some other things related to certificates but still no luck.
    Solved!
    Go to Solution.

    Evetually I took Techfreak's suggestion and sniffed the packets with wireshark. Was annoyed to discover that the root cause of the issue was suspiciously named sb.symcd.com.
    Some quick Google-fu led me to a page which advised that this domain should be whitelisted for Lync installations. Hmm.
    Why microsoft could not use more intuitive/descriptive server names is a mystery. Anyway, I whitelisted *.symcd.com and from the limited testing it appears to be resolved.

  • Login screen alterations.

    I recently found out you can create custom login screen pictures and remove the apple logo and so on.
    A part I also loved was the login message. I was wondering if anyone knew how to alter it so it could be made larger, text change and have new line capabilities (rather than having to space bar of to the end?)
    Thanks.

  • Where do I find my profile picture that is shown on my login screen?

    Using a Macbook Pro, OS X 10.7.1. I would like to know where I can find the picture that is shown on my login screen? (as a file that I can upload to the internet, edit, etc.)

    It might be in Photo Booth.

  • I updated my iMac to lion and now when i leave my desktop and it goes into stand by it like a picture is taken of the screen and when i want to log in the mouse point removes pixels so i can get to the user login screen this never happened ith snow leopar

    i upgraded my iMac to lion and now when i leave my desktop and it goes into stand by mode, its like a picture is taken of the actice desktop and when i want to log in the mouse point removes pixels so i can get to the user login screen this never happened ith snow leopard. does anyone else experience this and is there a fix?

    I have an iMac 8, 1 that I upgraded Leopard to Snow Leopard.  It was totally updated with the latest from Apple when I bought and tried installing Lion.  The upgrade failed, shot my OS and I couldn't boot.  Had the constant spinner on a grey screen..  did a format of the drive, hdd repair and everything came back clean... got back to Snow Leopard and all the updates on it again and then retried the Lion thing... same bs... dead duck.  Crashed my system one too many times.  I can't see where a few small changes, mostly app related can be classified as an OS upgrade and is not compatible with my iMac.  I have the stuff running on my Mac Pro but have yet to notice anything impressive.  I've always used F3 and really didn't require Mission Control.  Just open you app folder for launch pad... duh?  I use the hot corners anyhow.  As far as Safari is concerned... as a power user, Apple missed the boat on that for me.. full screen etc.. Wow.  I don't like the new Mail either..
    As you can see/read, I'm less than impressed with this release from Apple but I own so many of their products that I will have to put up with it for now... somehow the MS logo should apply to this release Steve.

  • Windows 8 Login Screen Issue

    After a reboot of the computer, one of my son's friends typed in an incorrect Microsoft username into the login screen. I can't get it to go away or let me delete it and log in with the correct username. No where to click, no where to get out of this.
    All of the information I have found online regarding the login screen requires me to make changes AFTER I'm logged in which is kind of the problem.

    Hi RobRosenbalm,
    Did you mean it stuck at the login screen with the incorrect username?
    If yes, please reboot it again to type the correct account to check the result.

  • Lion login screen problems on Mid 2009 MacBook Pro

    After upgrading my wife's Mid 2009 MacBook Pro from Snow Leopard to Lion we are seeing weird behavior on the login screen after the computer wakes from sleep mode.
    The screen is only partially drawn (usually the top left 1/4 of the screen), and the grey background is shown instead of her desktop background picture. When you move the mouse around on the screen, it repaints blocks on the screen where the pointer has been.
    This only seems to happen when the machine sleeps for a long period of time, e.g., overnight. When it just sleeps for a little while we don't see the issue.
    When searching the forums for anyone else with the problem, several folks said that there was an issue with the video drivers for the 9400M card and recommended switching to the 9600M GT, but her machine only has the 9400M in it.
    All other aspects of the system work fine.
    Anyone else seeing this? Any clues?

    Surprised there hasn't been anyone else experiencing this issue.
    I have seen this on 2 new MBP 2.3mhz i5's with the Intel HD 3000 384mb graphics, Lion 10.7.3 & 10.7.4.
    Also with the latest Lion firmware for the late 2011 MBP's that addresses compatibility and stability issues.
    Hopefully there is a fix soon because the painting on my locked screen to login is getting annoying

  • Outlook web login screen not displaying correctly on Exchange 2007 service pack install

    Hello everyone,
    I believe our exchange server installed a service pack 3 update and after rebooting the server, we noticed that the Outlook web access login screen is not displaying correctly.  The page looks white with some black X's (I think that's where the
    pictures/background images used to be).  We tried to restart the ISS service with no luck.  I would appreciate any help you guys can provide.
    Thanks,

    Hi,
    I have seen this issue in another similar thread, that issue was solved by re-creating the OWA virtual directory.
    Please try the following steps to solve this issue.
    Open EMC, navigate to Server Configuration -> Client Access, under Outlook Web App tab, double-click owa (default web site) properties.
    Then check InternalURL, ExternalURL, Forms-Based Authentication settings ect
    Open EMS, use Get-OwaVirtualDirectory get the list of virtual directories and identify the directory which is giving the problem.
    Remove it with this command
    Remove-OwaVirtualDirectory “owa (Default Web Site)”
    Now create it again with the following command
    New-OwaVirtualDirectory -OwaVersion “Exchange2007″ -Name “owa (Default Web Site)”
    Then configure the “owa” virtual directory settings like InternalURL, ExternalURL, Forms-Based Authentications etc… & check the OWA by logging with some test users.
    Best Regards.

  • When I boot up it hangs on the login screen for awhile, why?

    I have a mid 2011 Macbook Air 13".  It came with Lion but I recently updated to Mountain Lion.  When I wake the laptop from sleep everything is fine.  If it's been awhile since it slept (a couple of hours), the login screen hangs.  What happens is that it boots like normal and looks like everything is correct, but it won't let me type in my password.  After 10 seconds or so I can see a cursor come up but it won't let me type (but anything I do type at this point will later fill in the field after another 2-3 seconds or so).  One other thing that's weird is that when the screen first comes up it shows the battery percentage from when I put it back on the charger, then after everything catches up, it changes to show 100%.
    I hope I explained the problem well enough.  Basicly a "wake from sleep" is fine if it hasn't been long since the laptop slept, but if it's been awhile it takes about 15-20 seconds to boot up.
    Ideas?

    Here are some suggestions based on my recent issue with unable to get Mavericks up after upgrade - The Apple geniuses just simply couldnt figure this one out...despite it being in their shop for 3 days (They probably did not look at it...and asked if they can just wipe out everything and install fresh...i had said NO):
    Restart computer and hold Cmd+V when you hear chime. This will start the computer in Verbose mode.
    See the messages and see where the system boot fails. In my case, it was some backtrace IOStorageFamily issue with com.paragon-software.
    Google may be able to solve your Apple issues - just type the error message in and see if you get any useful suggestions. in most cases - this would be some faulty 3rd party drivers.....
    In my case, it was something stupid i had probably installed....I had to boot to safe mode (Hold Shift at boot chime) - open Terminal, delete the folder com.paragon-software.kext from System/Library/Extensions....that fixed the problem. Mavericks is working great now....
    Let me know if your debugging thing works...

  • How to enable login screen which doesn't require a password

    I'm setting up an image for a computer lab. The computers that are currently in this lab auto login. However, in the off case that a student accidentally (or maybe purposefully) locks the computer, we want them to be able to simply click the user account
    picture and it logs in without asking for a password. The current Windows 7 PCs in this lab work that way, but whoever set them up can't remember how this was accomplished and I can't figure out for the life of me how to get it done. Currently, if I lock the
    PC, it just brings me to the login screen with a blank username & blank password field.
    These machines are not on the domain. Does anyone have any idea how to get this behavior out of the login screen?

    BYPASS LOGIN
    Open a Run window (Windows Logo key+R), type netplwiz and press Enter. Remove the tick from “Users must enter a user name and password” > OK. You may have to type the user account name/password just the once to complete the process.
    BYPASS ENTERING A PASSWORD AFTER WAKEUP
    To bypass entering a password after hibernation, go to Control Panel > All Control Panel Items > Power Options > Require a password on wakeup (in the left pane) and put a check mark in Don’t require a password.

  • Macbook air built-in keyboard/trackpad only work at login screen

    The built-in keyboard and trackpad have become unresponsive on my 2013 refurbished macbook air. When I restart it, everything works normally at the login screen, but becomes unresponsive again once I've logged in. The computer works fine with external inputs or a shared screen.
    I've recently updated to yosemite. The fact that everything works up until login makes me think this is a software problem. I've tried all the troubleshooting steps listed here, and I've reset PRAM and SMC. Does anyone know what could be causing this?

    Hi,
    I was able to get result from apple store after 24 days not hours days. They said it's my fault and they have found liquid inside of it and when i asked to see pictures of it they asked for COURT ORDER and repair will be cost around 400$.
    I am %100 sure that my macbook air never touched with liquids.
    I was using it for business and not even fluids there isn't any one scratch on it. I have been very careful.
    Did they asked 400$ for you too ?
    I am also using mac mini and iphone 5s. I think i will never buy an apple again.
    And i will definetly go to court.

  • I have OSX 10.5.7 on my Intel Mac. When I try to login using the correct password the screen goes white and just returns back to the login screen. It does not jiggle like when you enter the wrong password.

    I have had a number of issues with my Intel Mac recently and had to reboot using disk utilities, safe mode, OSX recovery, but always come back to the login screen but when I type my password the screen goes white and returns to the login screen. My password is correct and the login does not jiggle as it would if the password was wrong. Please advise,

    Back up all data if you haven’t already done so. There are ways to back up, even if you can’t log in. Before proceeding,you must be sure you can restore everything to the state it’s in now. If you’re not sure you can do that, STOP.
    The procedure below may spare you the need for a clean reinstallation of OS X. If you don't feel comfortable carrying it out, don't. try.
    Briefly, you need to delete the following file:
    /var/audit/current
    If you already know how to do that, you can skip the rest of this message. Do it, and try again to log in.
    Boot in single-user mode by holding down the key combination command-S at the startup chime. If you’re using an external USB keyboard, it must be plugged directly into a built-in port on the Mac, not into a hub. Release the keys when you see a black screen with scrolling white text. In this mode, there’s no graphical interface; just a command line. Initially, you can’t make any changes to files.
    When the text stops scrolling, and you see a line ending in a pound sign (“#”), type the following command:
    mount -uw /
    You must type the command exactly as given, with no mistakes. If you don’t feel able to do that, STOP. At this stage, no harm will be done if you make a mistake, but later, it will be. Press the return key.
    Next, type the following command:
    rm -i /var/audit/current
    Press return. You should get the following output:
    remove /var/audit/current?
    If that's not what you get, STOP. Type the single letter N, press return, and try again. Otherwise, type the single letter Y and pressreturn.
    Finally, enter the command:
    exit
    Press return. The text will start scrolling again, and then the system will reboot. Try again to log in.

  • My MacBook Pro is now asking for a login. When I enter my passcode, it goes to a blue screen and back to the login screen. I saw several older posts, but nothing recently. I am running Snow Leopard.

    My MacBook is now asking for a password. When I login, it loops to a blue screen, and back to the login. Incorrect logins create a shaking of the login screen. I tried restarting with the shift key depressed, with no luck.

    I performed a hard shutdown, and upon start I could access my system without logging on. I'm not sure what caused the issue, but I have not booted up in almost a week.

  • I am having problems rebooting my mid 2009 macbook pro (grey screen other issues), need help!

    I am having problems rebooting, I have experienced the same problem as others with the grey screen but my case is a little different, It started with my mid 2009 macbook pro acting a little slower than normal, the screen would freeze, mouse wouldnt move and i'd be forced to "force reboot" this went on for a couple of days until i was tinkering with the wifi connection and it froze again. I had to reboot and this time i noticed that it took a long time to get to the login screen. i put in my password and it went into infinite load (i also tried the guest account and other accounts with same result). i tried rebooting again and the same thing would happen. after several reboots, the screen just stayed grey, sometimes with the apple logo and gear sometimes without it. Since its a 2009, (and for the most part, still works like a champ) i decided test the ram, i took one stick of ram out at a time to see if i could notice anything wrong with them. when i stuck just one in, the mac was still having the same problem rebooting. i pulled that ram and and stuck in the other and i noticed that this time the apple logo never appeard and a big crossed out circle appeared. figuring that the ram must be the problem, i ordered new ram and installed it. i noticed that when i rebooted for the first time with the new ram it was rather quick and took me straight to the login screen and i was able to log in with no problem. at this point i thought the problem was solved, but i noticed the macbook still acting funny. at first, none of my files appeared on my desktop or in the finder window. after about 20 minutes, everything magically popped up. i also noticed long pauses/freezes with the colored pin wheel spinnig. i closed the laptop and opened it again and the screen just stayed black. i tried rebooting again, and again i got the grey screen with no signs of being able to log in... i waited about 20 minutes and tried to reboot again and again i was able to log in, however the macbook is still acting slow and will freeze with no signs of unfreezing without a reboot.
    my macbook is 5 years old and has plenty of miles on it, so i understand if the thing needs to be replaced alltogether but does anyone know what could be the issue? could the bad ram have corrupted the hard drive in anyway? would re-installing the OS fix it?? and if so, how would i do that if i downloaded mavericks from the app store? are there any other solutions to this problem?
    all my files and what not are backed up on an external HD so theres nothing on it that i'd miss desperately if i had to whipe the hard drive but id really like to get her working again without any whiping of the HD. if anyone can help me out, it'd be greatly appreciated

    It is very difficult to offer troubleshooting suggestions when the "os version" you are using is unknown as each os has their own troubleshooting solutions. 
    How large is your hard drive and how much hard drive space do you have left?
