Greetings all, We're having a reoccurring issue which seems to be coming up every time there is a software update to macOS (like what we call a "dot-dot" update) on our lab machines (which are still on Mojave for another few weeks of Summer session). We get a dialog that looks like the following: Boot Recovery Assistant A software update is required to use this startup disk. You can update now or select another startup disk. (Startup Disk)   (Update) Hmm, this system won't let me link to my Google Drive for an actual picture of the screen. Moving on... Anybody can click the Update button and it proceeds along its merry way, but it is a real pain to have this show up on a bunch of machines in a lab or in classrooms. My Google-Fu has been unsuccessful in turning up a way to solve this issue (other than running around and clicking Update everywhere). Any ideas on why this happens, and how to get rid of it proactively?
