The quickest way to check whether a MacBook is charging is to click the battery icon in the menu bar or open Control Center. macOS will show whether the Mac is using battery power, connected to a power adapter, charging, fully charged, or not charging.
The exact signs depend on your MacBook model. Older MagSafe chargers have a coloured LED indicator, while most modern USB-C MacBooks show charging information on the screen instead.
1. Check the Battery Icon in the Menu Bar
Look in the top-right corner of your MacBook screen for the battery icon.
Click it to view the current power status. You may see messages such as:
- Power Source: Power Adapter
- Charging
- Battery Is Charged
- Not Charging
- Battery Health Management On
- Optimized Battery Charging
If the menu says your power source is a power adapter and the battery percentage is increasing, your MacBook is charging.
2. Check Charging Status in Control Center
On newer macOS versions, Control Center provides a clear view of battery information.
- Click the Control Center icon in the menu bar.
- Select Battery.
- Review the current battery percentage and power status.
If your MacBook is connected to a charger, macOS should indicate that it is receiving power or charging.
3. Look for the Lightning Bolt on the Battery Icon
When a MacBook is connected to power, the battery icon may show a lightning bolt or another charging-related status indicator.
However, do not rely only on the symbol. Click the battery icon to read the detailed text, especially if the percentage does not appear to rise.
A MacBook can be connected to a charger but still show Not Charging if the adapter is too weak, the battery is full, or macOS is protecting battery health.
4. Check the MagSafe Charger Light
Many older MacBook Air and MacBook Pro models use a MagSafe charger with a small LED light on the connector.
| MagSafe light colour | Meaning |
|---|---|
| Orange or amber | The MacBook battery is charging |
| Green | The battery is fully charged, or the MacBook is running from the power adapter |
| No light | Check the cable, adapter, wall outlet, and charging port |
If the MagSafe connector does not light up, disconnect it and reconnect it carefully. Check for dust, debris, or visible damage around the connector and port.
Modern USB-C charging cables do not usually include this LED indicator.
5. Check Battery Settings in macOS
You can see more detailed charging and battery-health settings in System Settings.
On Newer macOS Versions
- Click the Apple menu.
- Select System Settings.
- Click Battery in the sidebar.
- Open the charging or battery-health details if available.
On Older macOS Versions
- Click the Apple menu.
- Select System Preferences.
- Choose Battery.
Here, you may see options such as Optimized Battery Charging or a charge limit.
Why Does My MacBook Say “Not Charging”?
“Not Charging” does not always mean there is a fault.
Your MacBook may be connected to power but temporarily not adding charge for several reasons:
- The battery is already full.
- Optimized Battery Charging is active.
- A charge limit is enabled.
- The charger does not provide enough power.
- The MacBook is using more power than the adapter can supply.
- The charging cable, adapter, port, or wall outlet has a problem.
- The battery temperature is too high or too low.
If the MacBook stays connected to power and works normally, but the battery remains at a high percentage, battery-health features may be managing the charge level.
What Is Optimized Battery Charging?
Optimized Battery Charging is a Mac feature designed to reduce battery wear over time. It learns your charging routine and may delay charging beyond a certain level until closer to when you normally use your MacBook on battery.
For example, if you keep your MacBook plugged in overnight, it may pause at a lower percentage for some time instead of holding the battery at 100% for many hours.
This behaviour is normal and does not necessarily mean the MacBook is failing to charge.
How to Check if a USB-C MacBook Charger Is Working
Most recent MacBooks charge through USB-C or MagSafe 3. Follow these checks if you are unsure whether the charger works.
Check the Cable Connection
Make sure the cable is fully inserted into both the MacBook and the power adapter. If your MacBook has multiple USB-C ports, try another compatible port.
Check the Wall Outlet
Plug another device into the outlet to confirm that it supplies power. If you use an extension board or surge protector, test the charger directly in a wall outlet.
Use a Suitable Power Adapter
A low-wattage USB-C adapter may charge slowly or may not charge the MacBook while you are performing demanding tasks such as gaming, video editing, or using several external devices.
Whenever possible, use the Apple adapter that came with your MacBook or a certified USB-C Power Delivery charger with sufficient wattage.
Try Another Cable
USB-C cables can look similar but support different charging capabilities. A damaged or low-power cable may prevent reliable charging.
Try another known-working USB-C charging cable if available.
How to Tell Whether Your MacBook Is Charging While Turned Off
If your MacBook is shut down:
- Connect the charger securely.
- Wait a few minutes.
- Press the power button.
If the battery was completely empty, the MacBook may need time before it can start. You may see a low-battery symbol or a charging screen after connecting power.
For MacBooks with a MagSafe LED, an orange light indicates that the battery is receiving a charge.
How to Fix a MacBook That Will Not Charge
Try these steps in order.
1. Disconnect and Reconnect the Charger
Unplug the charger from the wall outlet and MacBook. Wait a few seconds, then reconnect both ends firmly.
2. Inspect the Charger and Port
Check for:
- Frayed or damaged cables
- Bent connector pins
- Dust or debris in the charging port
- Overheating power adapters
- Loose wall sockets
Do not use a visibly damaged charger or cable.
3. Restart Your MacBook
A restart can resolve temporary software or power-management issues.
- Click the Apple menu.
- Choose Restart.
- Reconnect the charger after the Mac starts again.
4. Update macOS
Open System Settings > General > Software Update and install available updates. macOS updates can include battery, charging, and power-management improvements.
5. Reduce Heavy Power Use
If you are using a low-power adapter, close demanding apps, disconnect unnecessary accessories, and see whether the battery begins charging.
6. Check Battery Health
Open System Settings > Battery and review battery-health information if available. If macOS recommends service, contact Apple Support or an Apple Authorized Service Provider.
When to Contact Apple Support
Contact Apple Support or a qualified repair provider if:
- Your MacBook will not charge with a known-working compatible charger.
- The battery percentage never increases.
- The charging port is loose, damaged, or hot.
- The MacBook shuts down immediately after unplugging.
- macOS shows a battery-service warning.
- The adapter, cable, or MacBook smells burnt, becomes unusually hot, or shows physical damage.
Avoid opening the MacBook or attempting battery repair yourself unless you have the appropriate technical experience and tools.
Frequently Asked Questions
How do I know if my MacBook is charging?
Click the battery icon in the menu bar or open Control Center. macOS will show whether the MacBook is charging, connected to a power adapter, fully charged, or not charging.
Does a green MagSafe light mean my MacBook is charging?
Usually, a green MagSafe light means the battery is fully charged or the MacBook is running from the power adapter. An orange or amber light indicates active charging.
Why is my MacBook plugged in but not charging?
The battery may be full, Optimized Battery Charging may be active, the adapter may be too weak, or there may be a cable, port, outlet, temperature, or battery-health issue.
Can I use any USB-C charger for my MacBook?
A compatible USB-C Power Delivery charger may work, but it should provide enough wattage for your specific MacBook model. Using an underpowered charger can lead to very slow charging or no charging during heavy use.
Why is my MacBook charging slowly?
Slow charging can happen when using a low-wattage adapter, a weak USB-C cable, a busy USB hub, a damaged cable, high system power usage, or a warm battery.
Final Thoughts
The most reliable way to tell if your MacBook is charging is to check the battery menu in macOS. Older MagSafe models also provide a simple visual clue: orange means charging, while green usually means the battery is full.
If your MacBook is connected but does not charge, start with the cable, adapter, wall outlet, and battery settings before assuming the battery needs replacement.
