Applies to: Sophos Home Premium and Free (Mac)
On a macOS 10.13 computer, an alert is received saying This Device is Vulnerable, however, all the protection is enabled. This issue happens on a Sophos Home protected macOS 10.13 computer that has too many applications that register virtual devices.
Cause
The issue happens not because of Sophos but due to the macOS limitation regarding the virtual devices limit. The issue is that there are too many applications that register virtual devices. The most common applications that do this are VirtualBox and VMware as they use up a number of virtual device slots. In addition, Sophos Home also needs virtual devices slots. So, when the system has not enough virtual device slots, whichever application loads last will result in this error.
Workaround
To fix this issue, remove one of the applications and restart the Mac computer.
