"Frozen Mac screen: I was using my MacBook and suddenly the screen completely froze while I was full screen in an app. I looked online for how to fix it but I think I may have messed it up.. how can I fix it??"

Successfully Quitting an App:

Seems you need for Force Quit this app.

Two steps:

I. Using [command + tab]:

Use [command +tab] to get to Finder (the smileyface). Then, Force Quit the App. Read my User Tip: [command+tab] Use it to Access your Mac when Something is Not Responding - User Tip

II. Using Force Quit:

See if this applications open. If that is the case, save what need be (if possible), and then Force Quit.

1. Go To: Apple Menu
2. Select: Force Quit...
3. Select: Mail
4. Click: Force Quit button

Hi,

Hold down the power button for up to 10 seconds until the Mac shuts down, then start up normally.
