My magic mouse button are working but my cursor isn't moving

You say Magic Mouse button. Is it a wired mouse?

I have the same problem. The cursor doesn't work but the surface it's perfect. The sensor in the bottom (i don't know if it's the word, i'm not very good in English) is not working, that's what i think. Is there a solution for this? I'm desperate.

Try using a cotton bud dampened, not wet, with whisky or medicinal alcohol and swizzle it around to clean it. Finish off with another cotton bud, dry this time. Unfortunately Shashank failed to respond, but if yours is a wired mouse, disconnect it first.
