Is your MacBook Pro randomly shutting down, even with plenty of battery life left? You’re not alone; reports of MacBook Pros shutting off prematurely are showing up on various forums and support threads. So far Apple has confirmed the random shutdown behavior on the 2019 13-inch MacBook Pro.

What to Do When Your Mac Keeps Shutting Down

When you experience a random Mac shutdown, the first and most important step is to boot it back up, then immediately restart it again. Doing this is necessary because programs don’t always close correctly during a hard shutdown.

To restart again, select Restart from the Apple menu in the top-left corner. Unfortunately, just rebooting your Mac might not solve the problem. In this case, Apple recommends resetting the computer’s System Management Controller (SMC).

What is an SMC in Mac Computers?

SMC is what remembers your battery full charge capacity and also the lowest capacity, so it can go to sleep or shut down the computer before the battery fully dies.

So when you replace a new battery the full charge capacity will be a lot higher than your old battery so the charge level of your new battery will not be accurate.

How to do an SMC reset on MacBook that randomly shuts down

Before resetting the SMC, Apple recommends taking the following steps, in the order they are listed:

  • If the Mac isn’t responding, press and hold the power button until it shuts down. Then press the power button again to turn on your Mac.
  • Press Cmd + Option + Esc to force-quit any app that’s not responding.
  • Put your Mac to sleep by choosing Sleep from the Apple menu. Wake the computer after goes to sleep.
  • Restart your Mac by choosing Restart from the Apple menu.
  • Shut down your Mac by choosing Shut Down from the Apple menu.

  • Hold those buttons together for at least 10 seconds.
  • After 10 seconds, release all the buttons at the same time.
  • Now start your MacBook or MacBook Pro by pressing on the power button.
  • Now the SMC will be successfully reset.

After resetting the SMC, you have to recalibrate your new battery to make sure the SMC has the correct full charge capacity of your battery. Charge your battery to full and keep the power cable plugged and keep using your MacBook. Then, after a few hours of using the MacBook, you can remove the charging cable and let the battery drain until it shuts down. Do this several times to calibrate the battery. This will prevent a shutdown of the MacBook at 20% or higher once the battery recalibration is done.
