10.15.7 client installed Security Update 2021-003 but now shows build 19H1217
The end user installed Security Update 2021-003 via System Preferences Software Update. Days later the machine shows build 19H1217.
When I run Softwareupdate -list or visit System Preferences Software Updates no updates are available.
The computer is a MacBook Air (pre retina)
Ideas?
MacBook, OS X 10.10
