It happened now several times to me (on several different computers) that the App Store application wants me to update to the latest OS version although I did this already (with a downloaded combo updater). In this case I updated to macOS 10.12.3 and still see in the App Store application that I should update to exactly the same macOS 10.12.3. See screen shot. If I do this now the whole download happens again. This is a relatively new phenomenom, probably since macOS 10.12 Sierra only. I am since many years always updating with a downloaded combo updater and never had this before. How can I prevent this in macOS 10.12 Sierra?
