Re: custom lock message (again)

Patrick / All 
Thanks for the post on how to kill the screen memo ... very useful 
As for your question on how to change the lock image , you were in the right place , but not deep enough into the rabbit hole. 

An no ... the apple directions don't work , I tried it for hours...  

The file you are looking for is in this path :


So , System Lib. - > Core Services - > Remote Management -> Open the AppleVNCServer.bundle -> Open the bundle / Resources -> Bam (LockScreen.jpg)

Be careful not to run the ... because you will then lock your own screen. ;) so I've been told by someone who did this ...

Edit this file on the host machine , and in the little bit of testing I have done , it works well. 

Consider the fact that image resolutions do matter , so try to create an image in the resolution of your client computer .. (i.e widescreen v. traditional aspect ratios)

Anything related , please throw back @ me !

Just in case anybody's interested: I the following modification from an earlier ARD 2 thread in version 3, and it still works. Many thanks again to Anthony Foxcroft who contributed it:

If you do not want the client to know who locked their screen (for whatever reason) try the following. Note: If you're not comfortable hacking pref files... leave well alone.

Since ARD 2.0, when an administrator locks a screen, the locked screen tells who did it. At times you might not want clients to know who is controlling the computer.

  1. Make sure Apple Remote Desktop is not running, and navigate to the folder containing the application.
  2. Control-click on the application and choose "Show Package Contents" from the pop-up menu.
  3. In the window that opens, navigate to Contents/Resources/English.lproj (or whatever language you're using).
  4. Find the file "LockScreenTask.strings" and create a backup copy in a safe place.
  5. Open the original "LockScreenTask.strings." If you have the Developer Tools instaled, it will open in Xcode; otherwise, you can open it in TextEdit.
  6. You should see the following:
  7. /* Localized versions of task strings */
  8. taskString = "Lock Screen";
  9. taskDescription = "Lock Screen";
  10. longTaskDescription = "Lock screens on target computers";
  11. actionString = "Lock Screen";
  12. lockedByString = "\r\rScreen locked by %@";
  13. lockedByStringNoText = "Screen locked by %@";
  14. defaultPictureName = "Lock Screen Picture";
  15. // Task progress
  16. kLockScreenRequestingOne = "Locking screen";
  17. kLockScreenRequestingMany = "Locking screens";
  18. Change the line lockedByStringNoText = "Screen locked by %@"; to lockedByStringNoText = "";. Now "Screen locked by" will not appear when you lock the screen of a client computer if you don't type a message, but it will still appear if you do.
  19. If that's not sufficient, replace the line lockedByString = "rrScreen locked by %@"; with lockedByString = "rr";. Now the "Screen locked by..." message won't appear even if you send them a message.
  20. Save your work, launch ARD, and you're done.
But like in ARD 2 I'm still not successful in changing the Lock Screen Picture:

Create an image with the words, picture etc that you want the user to see. Save it as – Lock Screen Picture.jpg – push this out to your clients /Library/Preference folder. The next time you lock their screen this image will be the one they see. If you want to revert to the standard lock image, remove this image.

This doesn't work, so I removed it and replaced the Lock.jpg inside the ARDagent, but the Mac still shows the original lock picture. Where can it come from? Does the admin machine send it? Is there any other lock.pict location?
