As a rule of thumb, always check the frequency of update errors.

If you are connected to the internet and Bitdefender Shield is enabled, Bitdefender Antivirus for Mac checks for updates every hour. If an update is detected, it is automatically downloaded and installed on your Mac.

You can also perform manual updates at any time. An active internet connection is required to check for available updates and download them. To request an update manually:

1. Bring up Bitdefender Antivirus for Mac.
2. Click Actions in the menu bar.
3. Choose Update threat information database.

Update error What it means and how to fix it

-1011

or

-1002

The update error codes -1011 and -1002 indicate that the Mac doesn’t have internet access. It is caused by an issue with the internet connection – it times out because it’s not at full strength or it’s temporarily interrupted.

Usually, such error message is followed by a successful update as soon as the Mac reconnects to the internet. To check this, open the Notifications section from Bitdefender Antivirus for Mac. This will reveal all the product events and if the last one is a successful update, then you have nothing to worry about.

If it’s not, and you are using a Wi-Fi connection, try to connect your Mac to the internet using the cable, and perform a manual update.

If the error persists, try changing the DNS settings:

– open System Preferences on your Mac
– go to the search bar located on the right hand side of the window and type in DNS then select DNS servers from the search results
– click the + button under DNS Servers and enter 1.1.1.1
– click + again and enter 1.0.0.1 (This is for redundancy.)
– click + again and enter 2606:4700:4700::1111
– click + again and enter 2606:4700:4700::1001 (This is for redundancy.)
– click OK, then click Apply

If the update still encounters errors and you have a router firewall, 3rd party firewall apps or network monitoring apps such as Little Snitch, temporary disable them in order see if Bitdefender updates successfully.

To turn off macOS firewall:

– open System Preferences
– click the Security & Privacy icon, then access the Firewall tab
– if it’s enabled, click the small padlock in the bottom-left corner of the window
– enter your administrator password when prompted, then click Unlock
– click the button Turn Off Firewall

If the update error persists, check your proxy settings:

– open System Preferences
– click the Network icon, then click Advanced at the bottom of the window
– open the Proxies tab
– disable Auto Proxy Discovery or any other options checked under Select a protocol to configure
– add *.bitdefender.com inside the Bypass proxy settings for these Hosts & Domains section, then click OK

– open the Proxies tab
