Ok, I have a base 15" mbp 2010 model. I wanted to restart my laptop several times and this happened about twice now. I had to force shutdown by holding the power button, but this can't be healthy for it. Here's what happens, I go to apple>restart and then my desktop icons and taskbar, finder bar goes all away so that only my desktop background is showing, and it stays there. I can still move the cursor with my trackpad but me being new to macs, i don't know any keyboard shortcuts to bring up the activity monitor and stuff. Is something wrong with my macbook pro? Any help is appreciated, thanks.
