OKay so yesterday night I updated my Mac Mini. This morning I wake up to see my entire desktop, blasted to the front. It's like it's set to a much lower(higher?) showing a lot more grain, everything is pumped to the front, it's just bleck! I can't even see the top bar to help turn my computer off/on, restart...etc... I've already tried to change resolution, but to no avail. That background was even the one I had before the update. Here's a screenshot so you mac experts can give me a solution Thanks so much for all of your help!
