Sophos Anti-Virus for Mac: Support for Apple MacOS 10.14 Mojave

This knowledge base article provides information about the support for Apple MacOS 10.14 Mojave by the Sophos Anti-Virus.

The following sections are covered:

Applies to the following Sophos products and versions

Central Mac Endpoint

Sophos Anti-Virus for Mac OS X

  • 9.6.5+
  • 9.7.1+
  • 9.8.0+

Dark Mode is not supported by Sophos Anti-Virus. It will maintain its existing colors when the OS switches to Dark Mode, but otherwise it is fully functional.

Due to a new security mechanism that Apple has released with MacOS 10.13, called Secure Kernel Extension Loading (SKEL), all non-Apple kernel extension (what we use to intercept files, etc) vendors must be manually added to a trusted list (Any user can add this). This allows the kernel extensions to load, and is required for Sophos Anti-Virus to function properly. All 3rd party vendors are impacted by this change, and it is not possible to work around this requirement.

Adding of the kexts is only applicable for Mac computers that are to be installed with SAV for the first time. Nothing is to be done on existing SAV on Mac that was installed prior to the release of the new security mechanism.

Due to an Apple security restriction, this cannot be done via a remote desktop connection. There must be a locally logged on user. The Allow button will show, but be grayed out if it is accessed via remote desktop.

  1. After installing SAV, go to Security & Privacy in the Apple System Preferences window.
  2. At the bottom, the listed Sophos kexts will appear.
  3. Click Allow.

Once authorized, all future Sophos kernel extensions will now be allowed, even after the uninstall. This step is not needed again on a re-install.

If the above approval did not work, take a look at the KBA 132813 for troubleshooting steps .
