I had a SD card in the reader and inserted a blank CD to burn pictures from one to the other. Maybe I didn't start in the correct order but I ended up canceling the burning, ejected the disc and tried closing Finder. But now when I select close, the MBP makes a noise. I've tried selecting command + Q but it won't quit finder. I tried shutting down the MBP but every time it makes the noise on the screen that shows the Macintosh HDD & Network beside of it in Finder I believe. Point is, I can't get it to go away nor shut down. Can anyone help me please? Thanks in advance. Edit: The MBP is responsive because I'm posting from it, but I can't get the screen to go away nor shut down.
