MacBook Air with Mojave 10.14.5 gets error when attempting to upgrade
I have "Security and Privacy" powered by McAfee that is provided via Verizon.
I've had it installed on a MacBook Air for at least one year. The last successful upgrade listed in the History was on May 6,2019. On May 13, 2019 the upgrade failed and it has failed every automatic upgrade attempt since and it also failed two manual upgrades today.
Security and Privacy Version: 126.96.36.199 (3646), Affid: 1393-1
Please advise on next step to getting this issue resolved.
