How To Fix CoreServicesUIAgent Stuck on Verifying macOS App

Have you ever encountered the issue of CoreServicesUIAgent not closing after downloading an app? This error is common for Mac users and can be frustrating as it prevents you from accessing your application.

CoreServicesUIAgent is an application verification process that occurs when you download apps from outside the Mac App Store.

The verification progress appears and may remain stuck, displaying messages such as “Verifying Google Chrome” or “Verifying Discord.”

No matter how many times you click the X, the window will not close, and the app won’t open.

In this tutorial, I will show you how to close the CoreServicesUIAgent on your Mac if it gets stuck in the verification process.

Restart your Mac

So what do you do if CoreServicesUIAgent won’t close? The first step is to restart your Mac computer.

To restart your Mac, click on the Apple icon located in the top-left corner of the screen. Then, select Restart from the drop-down menu.

If your Mac is frozen due to the CoreServicesUIAgent process, you can still force restart it.

Press and hold the power button until your Mac shuts down. Once the screen goes black, press the power button to turn the machine back on.

Use Activity Monitor to Close CoreServicesUIAgent

If for some reason, the CoreServicesUIAgent process is harder to close than expected, you can use the Activity Monitor app on your Mac to kill the problematic apps or processes.

Step 1: Open Spotlight Search on your Mac.

Step 2: Enter Activity Monitor and press Enter.

Step 3: Locate CoreServicesUIAgent under Activity Monitor.

Step 4: Double-click on each problematic app or process and click Quit.

In conclusion, restarting your computer and force quitting the CoreServicesUIAgent process will resolve it from being stuck on verifying the app on your Mac.
