“We recently discovered that a Chrome update may have shipped with a bug that damages the file system on macOS machines,” wrote a Google support employee in a forum post. "We’ve paused the release while we finalize a new update that addresses the problem.”
Keystone corruption
All affected machines seem to have been running Avid Media Composer – an industry standard video editing suite. However, this was a red herring, and the problem actually involved Google Keystone, which helps keep Google software up to date.
Google Keystone version 1.2.13.75 of contained a bug that damages the file system on macOS devices with System Integrity Protection (SIP) disabled.
SIP is a feature intended to stop malicious software modifying important system files. The problem also affected older Macs running OS X 10.10 Yosemite or earlier, which don't support SIP.
Most users won't have reason to disable SIP, but if your device has been affected, Google has published instructions explaining how to fix the problem.
