Have you noticed that the ContinuityCaptureAgent process is consuming a lot of CPU resources? You don't need to worry that this could be a virus or malware. ContinuityCaptureAgent is a legitimate operating system process. macOS, Developed by Apple, and is part of the Continuity suite of features. Continuity is a set of features that enables seamless integration and collaboration across devices. Apple, such as Mac, iPhone, and iPad, when they're signed in to the same iCloud account and nearby.
Specifically, ContinuityCaptureAgent is responsible for handling functions related to capturing content between devices. For example, it plays a role in features like Continuity Camera, which allows you to use your iPhone or iPad camera to take pictures or scan documents directly to your Mac. The process facilitates communication between devices to ensure that the workflow is smooth and that data (such as images or scans) is transferred correctly.
Here you can find a tutorial in which this process plays the main role: How to Use iPhone as a Webcam for Mac. Continuity Camera.

Why is the ContinuityCaptureAgent process consuming a lot of CPU resources?
The ContinuityCaptureAgent process is not normally a heavy CPU or memory user, as it is designed to run efficiently in the background. However, there are certain scenarios where it may use more CPU than usual, even for a very short time.
In my case, there was a sudden increase in CPU resources consumed, but it decreased very quickly after I turned off Continuity Camera.
Here are five scenarios where the ContinuityCaptureAgent process may consume high processor (CPU) resources:
1. Heavy use of Continuity Camera
If you use Continuity Camera frequently (for example, taking photos or scanning documents with your iPhone directly to your Mac), the process needs to handle the rapid transfer of data between devices over Wi-Fi and Bluetooth. This can temporarily increase CPU usage, especially if:
- Transfer large files (high-resolution images or multiple scans).
- The connection between devices is unstable, forcing the process to work harder to maintain synchronization.
2. Connectivity issues between devices
If Wi-Fi or Bluetooth is weak or intermittently disconnected, ContinuityCaptureAgent may consume more CPU trying to re-establish the connection to nearby devices. For example:
- Devices disconnect and reconnect frequently.
- There is network interference affecting communication.
3. Frequent sync or system errors
If multiple Continuity functions (Handoff, AirDrop, Continuity Camera) are used simultaneously, the process may take longer.
Sometimes, a system error (bug) can cause the process to enter a loop of repeated attempts to complete a task, which increases resource consumption.
4. Updates or initial setup
After an update macOS or when you set up a new device in the ecosystem Apple, ContinuityCaptureAgent may run more intensively to check compatibility and establish initial connections between devices.
In this situation, the problem of excessive CPU resource consumption will resolve itself after a while.
5. Unusual activity or corrupt process
Although it happens quite rarely, if the process is constantly consuming a high percentage of CPU for no apparent reason (for example, you're not using Continuity), it could be a sign of a problem:
- A corrupt system file.
- A third-party app that interferes with Continuity.
How do you check and fix high CPU usage?
Monitor activity: Open Activity monitor (Activity Monitor) and search for ContinuityCaptureAgent. Note the percentage of CPU used and what you were doing at the time.
Test the conditions: Use Continuity Camera or disable Bluetooth/Wi-Fi and see how your usage varies.
Restart devices: Sometimes a simple restart solves temporary crashes.
Update macOS: Bugs that cause high consumption can be resolved with an update.
Reinstall the process (advanced): If you suspect corruption, you can reinstall macOS to restore system files, but that's an extreme measure.
In conclusion, if you notice high resource consumption attributed to the ContinuityCaptureAgent process, it's best to check if you're using Continuity very heavily at the time. Most of the time, resource consumption returns to normal after a while, without the need for intervention.
