I've installed our Root CA cert in the "System" keychain, and have it marked as trusted. I can successfully decrypt web traffic from a MAC running Mojave. No problems there.
The problem comes in when I try updating the OSX or even check for updates from the CLI.
When I run "softwareupdate -l" in terminal, In the logs on the firewall it appears to be coming through as web browsing app, and getting decrypted.
I ran a packet capture, and it shows the client is resetting the connection after succesffuly going out to swscan.apple.com, which is not whitelisted for decryption exclusions. Has anyone run into issues when trying to decrypt on OSX with a trusted root cert, while trying to update the operating system itself?
Guessing adding these domains to decryption exclusion is going to fix this?
