Known Issues

“This device is vulnerable”

The computer needs to be restarted to complete the installation. If the system is still vulnerable after a reboot, update your macOS to the latest version and follow the Troubleshooting section below.

Network Filtering applications interference

Network filtering applications such as Little Snitch or VPN software running in tandem with Sophos Home or other software with network filtering capabilities, may trigger errors or not work at all. If you experience issues with Sophos Home or another network based program, we recommend either disabling or removing the other program and re-testing functionality.

LaunchPad/Applications folder shows several Sophos Home apps

After Installing/Updating to Sophos Home on Big Sur, you will see 3 Items in the new Launchpad/Applications folder:

  • Sophos Home
  • Sophos Scan
  • SophosWebNetworkExtension

Big Sur will show all the apps in the new launchpad. There is no action needed, nor will these apps launch the antivirus. To launch Sophos Home, please see Locating Sophos Home in your system
If desired, the apps can be moved to a folder to keep them all under one place:  https://support.apple.com/en-in/guide/mac-help/mh35840/mac
