After updating macOS, App Store keeps showing the same update again and again
I saw an update in the App Store for macOS 10.13.3. I ran the update which seemed to complete successfully. I did this weeks ago. However, I keep seeing the same macOS 10.13.3 update appearing in the App Store. When I ran the update a second and third time, it mostly just restarted my computer. When looking at "About this Mac" it shows I have macOS 10.13.3 installed, yet the update for that version keeps appearing in the App Store (see attached screen shot).
How do I fix this? I've already restarted my computer multiple times and have run the update multiple times, but it keeps coming back. Thanks!
