OSX Lion 10.7.4 breaks custom login screen!

If you are using any system tools such as Mackeeper, Onyx, Macaroni, or AppleJack, caches can get corrupted, leading to other systemwide issues. Stop using such tools. If this is an erase and installed and updated system that still doesn't behave as you believe it should for the screen to work, then I would give Apple a bug report here: http://bugreporter.apple.com/ after signing up for a http://developer.apple.com/ account and see if it is a known issue or not.

Onyx may be corrupting your capabilities by deleting or corrupting the cache files need to function. Stop using it, and find out from them how to make sure all its components are removed. The corruption though may be permanent until you erase and install your system.

Onyx caches the Login screen background and that is what you may be seeing when running Onyx.

If you use Easy Find and do a search for that file name it will turn up in a Onyx subfolder.

Leave it to Apple to limit, once again, what you can and can not change. Apple knows best and users should not fool with such things, Yeah Right.

Good Luck and best wishes.

Is the image you reference in your first post. Are you sure this is the image you wish to replace at startup?

Simple. They don't want users changing what they know to be the best background for the login screen.

When I have a chance to backup my Mac and upgrade to 10.7.4 I'll see if I can reproduce the problem. You might want to go to the Apple Store and see if they have any 10.7.4 installed machines already, and see if you can reproduce it there. Ask for help from the genius bar to see if the feature no longer works. They may need to login with their administrator password to allow you access to that folder.

Shootist have you reproduced the problem? Cause we don't know if Onyx might have corrupted the capability or not. Until it is reproduced on a system that has never had Onyx or other Cache tools, it is really hard to say there is a problem, or there is not.

No I personally have no need to change the login widow background image. It is just the login window and is only visible for the short time it takes me to type in my password.

I have not done a search on the issue but from one of the OPs posts he says it is a wide spread issue. So it would seem that either all those users are using Onyx, and that is part of the casue, or Apple has changed where that background get loaded from.

Right. If this problem isn't solved by tuesday, imma go visit that apple store after sending in my macbook for repair.

Why are you going to send it in for repair? Is it broken?

Lots of "me too" threads in the "More Like This" box to the right of your first post here - no solutions have been reported yet.

People using Onyx and such tools is also a widespread issue. Mac OS X contrary to popular belief does not need those tools for "maintenance" and should only be used on systems that are backed up to isolate certain problems. I have found no way though to eliminate the side effects of those tools, or to know when they'll happen or not, short of erasing the hard drive.
