Dark background

Is it actually a background pattern or just a solid color fill with some shadows added dynamically?

 

In Mavericks DP4 go to this location below

Code:

/System/Library/CoreServices/Setup Assistant

Run Setup Assistant, press continue then ⇧+⌘+4 then press Space, select the background to take a snapshot and quit by pressing ⌘+Q. This should be the result.

 

Wow. I never knew you could press space and only save a window or object. Nice.

 

Thanks for that! Just used Onyx to make this the logon background for ML. It's one thing I miss since removing Mavericks.

 

This may come as a surprise, but can anyone here explain how to do the opposite?

By that i mean replace the mavericks backgrounds of mc, nc and launch pad with the linen from 10.8

 

You can replace the login screen background with Onyx.

 

Where is the actual background location? The official release for Mavericks has a higher quality version of this grey background which I'd like to use elsewhere.
