I'm installing Norton onto my iMac and kep getting stuck at "Kernel Extension" as its asking to select "Allow" but the 'Allow" button does not show. The result is a loop whereby ever time i start my iMac i get the same warning that Norton is not fully installed.
Actual error message is "Click Allow next to the Symatec message. If you dont see the Allow button then , click here to retry" when i click a iMac screen opens, but this screen (Security & Privacy) does not have an "Allow" button to select.
