That worked - the MacBook Air booted normally into macOS 10.13.3, and when I intentionally installed 10.13.4, the installation proceeded properly. Rather than reinstall macOS right away, though, I tried something new: I held down the Option key at startup and then selected my boot drive. The log looked similar, and restarting had no effect. Shockingly, when the MacBook Air rebooted, it showed the same Installation Log screen and error. I know for certain that it was running 10.13.3, and I explicitly did not ask for 10.13.4 to be installed - I just wanted a quick restart to clear up the performance problems. (Did you know that different versions of Command-R cause different versions of macOS to be installed by macOS Recovery? Check out this Apple support article for the details.) Afterward, everything was fine, so I chalked it up to gremlins and started writing this article, but got sidetracked by work on our Internet infrastructure.Ī few days later, however, my MacBook Air was performing badly, so I decided to restart it as well. With seemingly no other recourse, I clicked Restart one last time, held down Command-Option-R to boot into macOS Recovery, and reinstalled the operating system.

I looked through the log and saved a copy, but none of the errors looked all that problematic. However, clicking the Restart button just brought up the screen and error dialog again. Instead of booting normally, I ended up at a screen containing only an Installation Log window and an error dialog saying “The macOS installation couldn’t be completed.” That was confusing since I hadn’t asked the App Store app to install macOS 10.13.4. Restarting my AirPort Extreme Base Station didn’t seem to help, so I restarted the Mac.

A few days ago, I got up early to get some writing done, but my 27-inch iMac’s Internet connection was being horribly slow, and the entire machine was struggling. It’s unusual that I see something entirely new on my Mac. 1647: Focus-caused notification issues, site-specific browser examples, virtualizing Windows on M-series Macs.#1648: iPhone passcode thefts, Center Cam improves webcam eye contact, APFS Uncertainty Principle.#1649: More LastPass breach details and 1Password switch, macOS screen saver problem, tvOS 16.3.3 fixes Siri Remote bug.#1650: Cloud storage changes for Box, Dropbox, Google Drive, and OneDrive quirky printing problem.#1651: Dealing with leading zeroes in spreadsheet data, removing ad tracking from ckbk.
