Troubleshoot common Bitdefender Antivirus for Mac installation errors
In all the situations above, proceed with the steps listed below.
1. Capture a screenshot displaying the error message. We will need this screenshot later, in case you open a Bitdefender ticket. You can take a screenshot by following the instructions presented in this article.
2. Download the com.bitdefender.agent.log.plist file from here and copy it to your /Users/Shared/ folder. This will generate agent logs that will help us identify the issue.
3. Restart your Mac in Safe Boot as described in this article.
4. Use Disk Utility and run a First Aid to check your disk for errors and to repair them.
• Go to Applications > Utilities and open Disk Utility.
• Select your startup disk (Macintosh HD) and click on First Aid
5. Go to the Applications folder and open the Bitdefender folder, then double click on the BitdefenderUninstaller file to uninstall Antivirus for Mac. You can find more details in this article.
6. Restart your Mac in normal mode and make sure you have a stable internet connection. The most common cause for the three issues described at the beginning of this article is a slow or unstable internet connection. If you use WiFi, make sure you have a good signal or switch to a wired connection.
Disable proxy settings & Mac Firewall, by following these steps:
• Open System Preferences

• Go back to System Preferences and open Security & Privacy
• Go to the Firewall tab: if it’s enabled, click on the Lock (in the bottom-left corner), insert your administrator password and then select “Turn off Firewall”.
Disable any 3rd party Firewall applications or network monitoring applications (such as Little Snitch).
NOTE: Once you successfully install Bitdefender Antivirus for Mac, you may re-enable the Firewall and other applications. Just make sure you allow all the Bitdefender connections.

• A BitdefenderProfiler_output.zip log generated with BDProfiler.tool. You can see how to do that in this article – How to generate a BDProfiler log.
• More details about your internet connection and about 3rd party Firewall applications you might have installed (see step 6.)
• The com.bitdefender.agent.log and com.bitdefender.credentials.log files from /Library/Logs/Bitdefender/agent
