macbook not started: sophos network extension and sophosscand

Out of two that I upgraded, one had a problem where one of those services was not started. Rebooting (again) the affected Mac fixed the problem for me.

Hi Downsideup, 

Thank you for reaching out to the Sophos Community Forum. Kindly refer to the following article to confirm if the required security permissions are configured:
macOS Security Permissions Required

I also suggest launching the "Endpoint Self Help" tool on the affected devices to check the permissions. The status including any suggested actions will be displayed on the "Prerequisites" tab. You may also reboot the device after this.

Let me know how it goes.

I managed to fix this by going into the security settings and giving sophos network extension and sophosscand permission to run. I do not have a screenshot but you will see a message in the Security preferences advising you that two services need permission
