Ok, this is a long story, but here's the abridged version; I have a mac mini. It has just come back from being repaired - replacement logic board. However, repaired it is not. Every time i try to start it up, I get a brief white screen with grey apple logo as normal, and then a black screen with white writing on. The writing is exactly the same text as you can see in the console system log when you start up a machine. It gets about a page-full through this, and then goes completely black. No vide at all. However, the machine is still working in there - I know this because I'm typing on it now via VNC. It is perfectly happy and all. It just does this weirdness start up and then no video. My question is twofold: 1. The company that repaired it claims that it booted fine before they gave it back to me; however, it hasn't since I've had it back. Could the boot behaviour be some kind of diagnostic thing they left on my machine, or a mode they left it in. If so, how do I get rid of it? 2. Failing this, does it sound like my vidoe card packed up maybe? Thoughts, solutions, etc., most welcome!
