Thank you for your speedy reply. The running app is AVG. First off I will quit the AVG app and run updater again.

I suspect that is your issue. Full Stop.

Third party AntiVirus is not recommended— it typically does nothing but add issues to the macOS and competes directly with Apple’s own built in security:

Uninstall  all third party apps that are Cleaners/Optimizers/Anti-Virus/VPN

all known to cause issues on the macOS

I would look for a in-app uninstaller ‚

If in doubt refer to the developers website; Support/Help/FAQ/known issues/compatibility/updates/uninstaller:

Contact a third party vendor

Uninstall AVG, like all antivirus apps they cause issues with MacOS and can mess up the system. Turning it off is not enough as there are all sorts of background tasks installed. Macs take care of themselves and don’t need antivirus or cleanup apps.

Out of curiosity what is this app running?
