Apache Web Server Not Starting In Xampp Mac

Common Issues and Solutions

1. Port Conflict

One common reason for Apache web server not starting in Xampp on Mac is a port conflict. Apache by default uses port 80, which might be occupied by another application on your Mac. To resolve this issue, you can change the port that Apache uses to a different number, such as 8080.

2. Firewall Blocking

Another possible reason for Apache not starting is that the firewall on your Mac is blocking the web server. You can check your firewall settings and allow Apache to communicate through the firewall. This can usually be done in the System Preferences of your Mac.

3. Incorrect Configuration

Incorrect configuration settings can also prevent Apache from starting. Make sure that the configuration files for Apache in Xampp are properly set up. Check the httpd.conf file and make sure the necessary paths and settings are correct.

4. Insufficient Permissions

Apache requires certain permissions to start and run on your Mac. If the user account you are using does not have sufficient permissions, it can cause Apache to fail. You can try running Xampp as an administrator or granting the necessary permissions to the user account.

5. Xampp Update

If you have recently updated Xampp on your Mac, it is possible that the update has introduced some compatibility issues or bugs. In such cases, you can try reverting to a previous version of Xampp or checking for any available updates or patches.

Steps to Troubleshoot

1. Check Port Usage

To identify if a port conflict is causing Apache to fail, you can check which applications are using port 80. Open the Terminal on your Mac and enter the following command:

 lsof -i :80 

This command will display the process ID (PID) of the application using port 80. You can then terminate or reconfigure the application to free up the port.

2. Disable Firewall Temporarily

If you suspect that the firewall is blocking Apache, you can temporarily disable it to see if it resolves the issue. However, it is important to re-enable the firewall after testing to ensure the security of your Mac.

To disable the firewall, go to System Preferences, click on Security & Privacy, and navigate to the Firewall tab. Click on the lock icon to make changes, enter your password, and then turn off the firewall temporarily.

3. Verify Configuration Files

Check the httpd.conf file in the Xampp installation directory to ensure that the necessary paths and settings are correctly configured. Look for any syntax errors or missing directives that may be causing Apache to fail.

You can open the httpd.conf file in a text editor and make the necessary changes. Save the file and try starting Apache again.

4. Run Xampp as Administrator

If insufficient permissions are causing the issue, you can try running Xampp as an administrator. Right-click on the Xampp application and select “Run as Administrator” from the context menu. Enter your administrator password if prompted and then try starting Apache.

5. Revert or Update Xampp

If you suspect that the issue is related to a recent Xampp update, you can try reverting to a previous version. Uninstall the current version of Xampp and install an older version that was working fine.

Alternatively, you can check for any available updates or patches for Xampp. Visit the official Xampp website or community forums to see if there are any known issues or updates that address the problem you are facing.


Apache web server not starting in Xampp on Mac can be caused by various issues such as port conflicts, firewall blocking, incorrect configuration, insufficient permissions, or compatibility issues. By following the troubleshooting steps mentioned in this article, you should be able to resolve the issue and get Apache up and running on your Mac.
