I can no longer play videos on my Mac mini.
I got a new magic mouse for Christmas. I connected it to my Mac mini Lion. It works great but I can no
longer play videos like from YouTube. I just see a black screen. Even the start triangle does not show up.
This is date coincident with installing the new mouse.
Does anybody have a clue what is going on here?
Thanks in advance.
