Users report serious multi-monitor configuration and stability issues in macOS 10.13.4
If you are running macOS High Sierra, it is best not to try the latest version. Although Apple stated in the release notes that “High Sierra 10.13.4 Update improves stability, performance, and security,” it is clearly not the case. According to the Register, many users reported that they had serious stability problems after installing version 10.13.4. Some unlucky users even discovered that when the system installed the patch and rebooted, it was found that the system was in recovery mode and the message “The macOS installation could not be completed.”
The diagnostics indicate that the disk is in good condition, so this is unlikely to be due to a hardware failure. At least one user reported that they could boot into safe mode and run again.
But another user complained on the Apple Stack Exchange that his Mac was booting into safe mode and stuck on a 100% interface.
At present, Apple seems to be unable to find out exactly why. In addition, ExtremeTech and Apple Insider also reported that macOS 10.13.4 has stability problems in multi-monitor configurations.
“DisplayLink is used to allow computers to run displays via USB technology,” says ExtremeTech. “It’s deployed across a number of different products, and there are software solutions that leverage it in various ways, typically to extend or clone a Mac desktop. And as of macOS 10.13.4, none of those solutions seem to be working — or at least, they’re not working normally.”
Duet posted a warning message on the support page to remind users don’t install 10.13.4:
“We recommend staying on macOS 10.13.3
Installing macOS release Version 10.13.4 will cause Duet Display stop functioning after the OS upgrade. We have alerted Apple to this issue and are working hard to find a resolution. These features continue to work as expected in 10.13.3.“
