Mac doesnt always save system preferences.

[Roofy.]

Sometimes Ill wake up my mac from sleep mode and things wil be changed. I have my background set to change every 30 min, and every once in a awhile it will revert back to the purple aura background, and that background isnt even in my wallpaper folder.

Today it did that, and also changed my display mode. My icons were huge, and the taskbar on the top was bigger. It went from 1024x800 to 800x600, or whatever the numbers are.

I also have an old crt monitor, i dunno if thats messing up ****.

If you mean the standard aurora background, I don't think it's stored only in the backgrounds folder, as it's also used when you're installing downloaded apple updates before shut down and some other cases.

If it's another one, you probably downloaded it from the internet. I know I saw one I downloaded stored as "http wallpaper" or something, in a folder other than backgrounds. I don't know where exactly though.
