Have a nice day.

Greetings punkandchicken,

Thank you for using Apple Support Communities. It seems like the MacBook Pro will unexpectedly shutdown after booting up. If you can get to the Desktop you may need to change some Energy Saver preferences.

Do you receive an error message?

Are you able to use the Mac at any point?

"Check your software

If the issue is caused by software on your Mac, one of these steps might help:

• Install all available software updates.
• If your Mac suspects that a particular app caused the restart, it might ask whether you would like to move the app to the Trash. Click Move to Trash, then contact the software developer to see if a software update is available.
• Use safe mode to try to isolate the cause of the issue.
• Reinstall macOS. If the issue continues after reinstalling macOS, check your hardware."

Please don't hesitate to let us know if the steps resolved your issue or if you need additional assistance.

Take care.

Hey punkandchicken,

Thanks for the update. It is possible that there is a schedule to put the computer to sleep.

Does the Mac go to sleep at the same time of day?

Has the MacBook Pro gone to sleep while in use more than once?

"On your Mac, choose Apple menu  > System Preferences, click Battery, then click Schedule.

Select the options you want to use.

• Schedule a startup or wake time for your Mac: Select the “Start up or wake” tickbox. Choose a day or group of days, enter a time, then click Apply.
• Schedule a sleep, restart or shutdown time for your Mac: Select the “Sleep, restart or shut down” tickbox and choose the appropriate option from the pop-up menu. Choose a day or group of days, enter a time, then click Apply."
