Solution 1Recommended

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.

1
Check Notification Center

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.

2
Open Activity Monitor

Navigate to Finder > Applications > Utilities, and double-click Activity Monitor to launch it.

3
Analyze Recent Processes

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.

4
Force Quit Suspect Apps

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.

System Alerts: If the pop-up has a generic system icon (like a gear or a caution triangle), it might be a macOS system alert rather than a third-party application.

Frequently Asked Questions

Why do I keep getting random pop-ups on my Mac?

Random pop-ups are usually caused by background applications, persistent website notifications allowed in Safari or Chrome, or software update agents (like auto-updaters for office suites or creative apps) trying to run in the background.

How do I stop website notifications from popping up on macOS?

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.

How do I turn off all notifications temporarily on Mac?

You can silence all standard notifications by enabling 'Focus' mode or 'Do Not Disturb'. Click the Control Center icon in the top right menu bar, select Focus, and turn on Do Not Disturb.
