The light bar also serves to alert users to notifications—such as messages, reminders, and missed calls—by changing colors or patterns.
3. Battery Status Notification
The light bar indicates the battery status, glowing red when the battery is low or yellow when charging, providing a quick glance at your device’s power.
Common Reasons for Light Bar Malfunction
When your light bar stops working, it could stem from a variety of issues. Here are some common reasons you might encounter:
1. Software Glitches
Sometimes, software updates or glitches in the operating system can disrupt the normal functioning of your MacBook Pro’s light bar.
