"New MacBook Pro shuts down at 25% battery"에 답변Got a replacement one today, it’s at 5% battery and gave warning as well, so far no issues! Also did you guys update the OS without plugging the charger. For the first one I updated OS with 100% battery, So thought charger won’t be required. For the second MBP I did have the charger plugged in while updating OS. Thought it might have caused some issues.
