Updated! Thank you.HeadsUp that the first link to the 10.14.6 Supplemental Update in the OP is incorrect and should be https://support.apple.com/kb/DL2015?viewlocale=en_US&locale=en_US
Try to click on the 10.14.6 text. It should show you the build number 18G95Updated the system with Supplemental Patch. When I go to "About This Mac", it doesn't show the supplemental patch code. Am I doing something wrong? What should I check for?
