MacBook screen frozen

Hi bostoninsf,

Thanks for posting. It's important to make sure your Mac is running as expected. I understand your Mac be unresponsive, and I'm glad to see if I can help.

You might want to start by seeing if you can force-quit any apps that are not responding: How to force an app to quit on your Mac

"How to force an app to quit

1. Press these three keys together: Option, Command, and Esc (Escape). This is similar to pressing Control-Alt-Delete on a PC. Or choose Force Quit from the Apple () menu in the upper-left corner of your screen. 
2. 
3. Select the app in the Force Quit window, then click Force Quit.
4.

If you're unable to access the Force Quit menu through the Apple menu or the keyboard shortcuts above, or if the issue persists, the suggestions below may be helpful depending on exactly what's happening:

• You can also force the Finder to quit, if it stops responding. Select Finder in the Force Quit window, then click Relaunch.
• If none of your apps are responding, you can force your Mac to restart."

Best wishes.

Try holding the start button so it restarts
