macOS 10.13.4 Causing Installation Log Failures
So let’s recap. In three separate instances, a Mac that’s running macOS 10.13.3 starts running slowly. Upon restart — without the user asking to install 10.13.4 — the Mac boots into the Installation Log app and shows an error saying the macOS installation couldn’t be completed. Restarting doesn’t help, but the first thing to try is holding down Option as the Mac boots and selecting the primary drive. If that doesn’t work, boot into macOS Recovery and reinstall the operating system. No data will be lost either way, but hey, make sure you have backups anyway!
How common is this problem? Unclear, although there’s a discussion of it on AskDifferent that covers the same ground I did. If you’ve already upgraded to macOS 10.13.4, you’re probably safe. But if you’ve been holding off upgrading, which is usually the cautious thing to do, be aware that it’s possible you might encounter this situation on your next restart.
Freaky.

Yep, that happened to me.
