High Sierra 10.13.1 refined support for HEVC (H.265) encoding, specifically for Macs with seventh-generation Kaby Lake processors. The update improved performance when exporting video from Final Cut Pro X and reduced thermal throttling during extended encoding sessions.
Enter . Released on October 31, 2017, this first major point update was far more than a bug-fix patch. It was the critical bridge between a promising but imperfect operating system and a reliable daily driver. For users still running older Macs or legacy software, understanding 10.13.1 is essential. This article explores everything from its installation process and security patches to performance benchmarks and compatibility quirks.
Backing up to a network SMB share (e.g., a Windows server or a Linux NAS) remained slower than with macOS Sierra. 10.13.1 improved reliability but not speed; initial backups could take 2–3x longer than HFS+ equivalents.
The primary purpose of 10.13.1 was to patch significant security vulnerabilities.
October 31, 2017 The Headline: While marketed as a refinement of the massive file system changes introduced in the base High Sierra release, version 10.13.1 will likely be best remembered as the update that officially brought the "Unicode 10 Emoji Standard" to the Mac.
, it unintentionally created one of the most significant security flaws in macOS history. The Root Vulnerability (CVE-2017-13872)
: Introduced a more efficient video codec that allows for 4K video streaming while taking up roughly 40% less storage space.
