why does MacOs 10.13 keep trying to install security update
Hi,
My iMac is from 2010 and has been obsoleted. It has MacOS 10.13 in called. Recently I installed Security Update 6 per the App Store. The list of installed software on the machine says that #6 has been installed yet the App Store is still trying to install it. Is there a way to stop/fix this?
Thanks
iMac 27″, macOS 10.13
