My Mac froze. I tried rebooting and now it won't boot past the blue screen. I have a mouse pointer and there is a small black circle with three smaller blue dots inside of it in the upper right hand corner of the screen. Clicking on it does nothing.
I tried booting in safe mode but it wouldn't boot past the galaxy screen. Again, I had a mouse pointer but nothing more.
I've tried booting from the OS disc that came with the computer. It sounds like the disc is running but nothing ever happens.
