Of course, the larger lesson is that it’s not a good idea to let a Mac’s internal drive get too full. What’s sufficient? That’s unclear, though 47 GB was enough, and some of the comments suggest that 20–30 GB would work. The moral of the story is to make sure you have sufficient free space before installing even a security update.

This time the update installed as it was supposed to. I downloaded GrandPerspective, my favorite utility for identifying large files, cleared 40 GB, and tried again. It was about 7 GB, which didn’t seem ridiculously low for just a security update, but after some hunting around on the Internet, I found some suggestions that too little free space could cause the installer to fail silently. On a hunch, I checked the free space available on the MacBook Air’s internal 256 GB SSD. I switched to a different admin account, but the problem recurred, all without any error dialogs that might have shed some light on the problem. I tried again, and once again, the Mac just restarted without installing the updates. The MacBook Air promptly restarted, and I logged in again, only to discover that nothing had been installed.

It wanted to install Security Update 2021-002 for macOS 10.15 Catalina and Safari 14.1, so I clicked the Update Now button and received a dialog telling me that I needed to restart to complete the update. I haven’t been using my old 2012 MacBook Air recently, so I wasn’t surprised when System Preferences displayed a badge alerting me to updates. #1653: Apple Music Classical review, Authory service for writers, WWDC 2023 dates announcedĬlear Space to Fix Catalina Update Restart Loop.1654: Urgent OS security updates, upgrading to macOS 13 Ventura, using smart speakers while temporarily blind.#1655: 33 years of TidBITS, Twitter train wreck, tvOS 16.4.1, Apple Card Savings, Steve Jobs ebook.#1656: Passcode thieves lock iCloud accounts, the apps Adam uses, iPhoto and Aperture library conversion in Ventura.
