After installing Mojave Security Update 2020-004 (not the latest 005, haven’t installed that one yet), Mac App Store shows that I have a number of software updates as it often does. When I click the “update” button for any update, the progress wheel spins for 10 - 20 seconds and then just stops. Nothing downloads.
I can download any software except for updates without problems on the Mac App Store. If I delete the update and search for it manually and download it, it works fine.
Anyone else having this problem? I’ve tried everything I can find on the net to resolve the problem to no avail. My first post, at wits end, been to TidBITS many times over the years.
