Reception
In his September 2017 review of High Sierra, Roman Loyola, the senior editor of ''
Macworld'', gave it a provisionally positive review, calling it an "incremental update worthy of your time, eventually." Loyola expressed that the product's most significant draw was its security features, and that beyond this, the most beneficial changes lay in its future potential, saying it "doesn't have a lot of new features that will widen your eyes in excitement. But a lot of the changes are in the background and under the hood, and they lay a foundation for better things to come."
Problems
macOS High Sierra 10.13.0 and 10.13.1 have a critical vulnerability that allowed an attacker to become a
root user by entering "root" as a username, and not entering a password, when logging in. This was fixed in the Security Update 2017-001 for macOS High Sierra v10.13.1.
When it was first launched, it was discovered that the
WindowServer process had a memory leak, leading to much slower graphics performance and lagging animations, probably due to some last-minute changes in Metal 2. This was fixed in macOS 10.13.1.
macOS High Sierra 10.13.4 had an error that caused
DisplayLink to stop working for external monitors, allowing only one monitor to be extended. When using two external monitors, they could only be mirrored. Alban Rampon, the Senior Product Manager for DisplayLink, stated on December 24, 2018 that the company was working with Apple to resolve the issue.
