How to Fix Acrobat Installer Saying Safari Is Open on Mac
Question details
The Acrobat Pro DC installer cannot proceed because it continuously detects Safari as open, even after the browser window has been closed.
- Product
- Adobe Acrobat Pro DC
- Device & OS
- Mac
- Scenario
- Installing or updating Adobe Acrobat Pro DC software on a macOS device.
- Observed behavior
- The installer is blocked by a prompt requesting the user to close Safari, despite the user having already exited the Safari browser application.
Before proceeding, ensure you have saved any open work in your browser and keep your Adobe account credentials handy in case a system restart is required.
Force-Quit Safari Processes Using Activity Monitor
Use the built-in macOS Activity Monitor to completely terminate any hidden Safari background processes preventing the installation.
On a Mac, simply closing a window does not always quit the application entirely. Hidden background processes like 'SafariNotificati' may continue running and trigger the Acrobat installer's detection.
Open Finder, navigate to the Applications folder, click on Utilities, and double-click Activity Monitor to launch it.
In the search bar located at the top-right corner of the Activity Monitor window, type 'Safari' to filter the list of active processes.
Select any remaining processes containing 'Safari' (such as SafariNotificati). Click the 'X' icon at the top of the window, and choose 'Force Quit' when prompted.
Once all Safari-related processes are fully terminated, restart the Acrobat Pro DC installer to continue.
Restart Your Mac to Clear Stuck Processes
A simple system restart is an effective way to clear all stuck background tasks if you are unable to find the specific processes manually.

Frequently Asked Questions
Why does the Acrobat installer think Safari is still open when the window is closed?
On macOS, closing the main window of an application does not always stop the app from running. Background services, such as extension handlers or notification processes (like 'SafariNotificati'), may continue running in the background, which the Acrobat installer detects as Safari being 'open'.
How do I properly quit Safari on a Mac?
To completely exit Safari instead of just closing its window, click 'Safari' in the top menu bar and select 'Quit Safari', or simply press the Command + Q shortcut on your keyboard.
Will force-quitting Safari delete my browsing history or bookmarks?
No, force-quitting Safari will not delete your browsing history, bookmarks, or saved passwords. However, any unsaved data or unsubmitted forms on currently open web pages may be lost.
