How to Identify and Stop Repeated Pop-Up Messages on Mac
Question details
The user needs to identify the source and content of a recurring pop-up message on their Mac in order to troubleshoot and stop it.

- Product
- macOS
- Device & OS
- macOS Sonoma 14.4.1
- Scenario
- A mysterious recurring alert or pop-up keeps appearing on the screen without clear indication of which software is generating it.
- Observed behavior
- An unknown application is triggering repeated pop-up notifications on macOS Sonoma, interrupting the user's workflow.
Before proceeding, keep a note of the exact time the pop-up appears and observe if it happens when a specific application is launched or running.
Identify the Source Using macOS Notification Center and Activity Monitor
Locate the app generating the pop-up by reviewing recent notifications and inspecting active system processes.
Most pop-ups on macOS are routed through the native notification system or tied to an active background process. Checking these areas can quickly reveal the culprit.
Click the date and time in the top right corner of your Mac's menu bar. Look through the list of recent notifications to see if the pop-up is logged there along with its application icon.
Navigate to Finder > Applications > Utilities, and double-click Activity Monitor to launch it.
Keep Activity Monitor open in the background. The next time the pop-up appears, immediately check the 'CPU' or 'Energy' tab for any unfamiliar applications that spike to the top of the list.
Select the suspicious process, click the 'X' button at the top of the Activity Monitor window, and choose 'Force Quit'. Observe if the pop-up stops appearing.

Capture a Screenshot for Support Analysis
Take a precise screenshot of the pop-up to share with support technicians, which helps in diagnosing the issue visually.

Frequently Asked Questions

Open Safari, go to Safari > Settings > Websites, and select Notifications from the left sidebar. Here, you can deny permission to any websites that are sending you unwanted pop-up alerts.
Can malware cause recurring pop-up messages on macOS?
Yes, adware or potentially unwanted programs (PUPs) can generate fake system alerts. If you suspect malware, consider checking your Applications folder for unfamiliar software or running a scan using a trusted Mac security tool.
