Watts is a menu bar battery management tool designed specifically for MacBook, offering comprehensive and intuitive monitoring of power and battery status to help users accurately track their device’s energy information.

As a menu bar application, Watts primarily provides the following three types of key information:
Through Watts’ settings, you can fully personalize the content and style of the menu bar icon:

The installation process for Watts is very simple, but to ensure smooth activation, please strictly follow these steps:
Download the Watts for Mac v3.0.0 activated version installer from this site. After downloading, double-click the .dmg file to mount it on the desktop. Then, drag “Watts.app” to the “Applications” folder.
Open the “Applications” folder and double-click the Watts icon. The system may prompt “Cannot verify developer”; in this case, go to “System Settings” > “Privacy & Security” and click the “Open Anyway” button. On first launch, Watts will request “Accessibility” permission to read battery status information; be sure to click “Allow”.
After launching, click the Watts icon in the menu bar and select “Preferences”. In the window that appears, find the “License” tab. Copy and paste the activation code provided by this site into the input field and click the “Activate” button. Wait a moment, and you will see the “Activation Successful” prompt.
After successful activation, restart the Watts application. Ensure the menu bar icon displays properly, and click it to view detailed data such as battery cycle count and capacity. If everything is normal, the installation is complete.
We have compiled the following common questions and answers for issues users may encounter while using Watts:
Please check “System Settings” > “Control Center” > “Menu Bar Only” to see if Watts is set to “Always Show”. Also, try restarting the application or rebooting your Mac.
Watts reads the battery’s original design capacity and current actual capacity, while system information may display optimized values. Trust the values shown by Watts, as they are closer to the battery’s true health status.
Open Watts’ “Preferences” and check “Automatically check for updates” in the “General” tab. When a new version is available, the app will prompt you. You can also directly download the latest version from this site and overwrite the installation.
Please ensure you are not using the same activation code on multiple devices simultaneously. If activation still fails, check your network connection or try disabling your firewall and reactivating. If the problem persists, please contact our customer service.
Not at all. Watts is merely a tool that reads battery status information; it does not modify any battery parameters, nor does it perform power-consuming operations in the background. It has no negative impact on battery life.
This is usually because you are not using an Apple original or MFi-certified charger. Some third-party adapters cannot be recognized by macOS, so Watts cannot read their power, voltage, and other information. It is recommended to use an original adapter.
Standard uninstall method: Move Watts.app from the “Applications” folder to the Trash. For thorough cleanup, go to the “~/Library/Preferences/” directory and delete configuration files starting with “com.23mac.watts”.
When using Watts, pairing it with the following macOS universal shortcuts can greatly improve operational efficiency. The table below summarizes the most commonly used shortcut combinations:
| Shortcut Combination | Function Description | Applicable Scenario |
|---|---|---|
| Command + , | Open preferences of the current app | Quickly access settings in Watts |
| Command + Q | Completely quit the current app | Quit Watts or background apps |
| Command + W | Close the current window | Close Watts’ detail panel |
| Command + Tab | Switch between open apps | Quickly switch between Watts and other apps |
| Command + Space | Bring up Spotlight search | Quickly search for Watts or related settings |
| Option + Click menu bar icon | Quickly view Watts’ detailed battery information | View data with one click without opening the main interface |
To help you fully leverage the value of Watts, here are several practical tips and real usage scenarios:
Many users don’t know how to check the battery cycle count. With Watts, simply click the menu bar icon and you can intuitively see the “Cycle Count” in the “Battery Health” section. For example, when your MacBook’s cycle count exceeds 1000, the battery’s maximum capacity is typically below 80%, and it’s time to consider a replacement. Watts will alert you to your health status with color changes.
A user reported that their MacBook was charging slowly. Using Watts’ “Power Adapter Information” feature, they discovered a third-party adapter with an output of only 20W was connected, far below the original 67W. After switching to the original adapter, charging speed returned to normal. Watts helps you quickly pinpoint the root cause.
A designer user set Watts’ menu bar icon to the “Lightning” style and hid the battery percentage, keeping only the icon. This keeps the menu bar clean and aesthetically pleasing while allowing quick judgment of battery status through icon color changes (green for normal, yellow for low battery, red for critical) without being distracted by specific numbers.
After enabling “Remaining Time Display” in Watts, combined with macOS “Energy Saver” settings, you can develop a more scientific charging strategy. For example, when Watts shows “approximately 30 minutes remaining to charge”, you can schedule your work in advance to avoid high-load tasks during charging, thereby extending battery life.
Watts for Mac v3.0.0 is a lightweight yet powerful battery management tool. Through its concise menu bar interface, it provides core data such as battery status, health parameters, and adapter information, with highly customizable options. Whether you are a regular user or a professional, you can benefit from it. The activated version provided by this site has passed rigorous testing to ensure stable operation. If you encounter any issues during installation or use, feel free to leave a comment below, and we will assist you as soon as possible. Protect your battery, start with Watts.
