How can I change the login screen background on Mavericks?

You forgot to block your contact details so you might want to remove that image.

To me it looks like the background was just scaled up, wich might have something to do with your retina display (I found this when googling: http://support.apple.com/kb/ht5266). Try fiddling with those settings and see if that works. Otherwise you can try scaling the image down, but that will result in a bad resolution of the background.

Lycka till!

Hi Kcasper,

Any chance you could change this to the right size for me?

Im using a 13' Macbook Air (1440 x 900)

Thanks so much

I still need a screenshot of your login screen. The reason for this is so that I know where the Apple logo is, which is important since that's what we're replacing and I need to know where on your screen it is so I know how much i need to add to the top and right to make the background centered. It's also important because I need to know where the buttons are. Furthermore, the picture you linked is not of high enough resolution to look good on your screen, but if you're okay with that I can certainly fix it for you, as long as you give me a screenshot.

I will get you a screenshot once I'm home tonight.

With regards to the resolution size of the photo, how bad do you think it will look?, and what resolution should I be looking for in a photo to make a good fit?

Cheers

You can just view the image in fullscreen to see how it would look. If you want optimal resolution it should be the same as your screen (1440x900) or bigger. Also, do you want the buttons at the bottom and/or the Apple logo included?

Hi Kcasper

I full screened the photo and tbh I dont think it looks that bad, we'll go with it. Including the buttons at the bottom would be great if you could, no apple logo though.

Thanks a bunch

Here's a PNG-file (just duplicate, rename and put in the right folder):

And here's a PSD-file, if you (or anyone else with the same resolution) want to change image:

Hope it works!

Kcasper, you are an absoulte champion! Thank you so much for that!!!

Dear Kcasper,

Do you know how to restore the default login screen background? My IT Department customised the login background and I would like to have my grey background and Apple logo back. I managed to ventured into /System/Library/PrivateFrameworks/LoginUIKit.framework, but I cannot seem to find the original files (apple.png etc.) online to which I can revert.

Thank you.

Hey Terrance,

I am attaching the 2 original files in case you haven't found it or it's lost.

Follow these steps:

In Finder Window go to Finder>Go>Go to Folder... then type and hit enter:

/System/Library/PrivateFrameworks/LoginUIKit.framework/Versions/A/Frameworks/Log inUICore.framework/Resources/

Then replace the images with these original images with the same file names.

Good luck!
