Chrome update causes Mac Pro to shutdowns

Google confirmed this week that the recently updated version of Chrome may cause macOS file system corruption, and some users have not been able to reboot the system since installing the new version of Chrome.

The first to discover this problem was a Mac Pro user who installed Avid Media Composer video editing software. They found that after the automatic update of Chrome, the system could not be restarted. It was originally thought to be an Avid software problem. Later, it was known that the updated Chrome had a bug.

Google Chrome vulnerability

Google explains:

We recently discovered that a Chrome update may have shipped with a bug that damages the file system on macOS machines with System Integrity Protection (SIP) disabled, including machines that do not support SIP. We’ve paused the release while we finalize a new update that addresses the problem.
If you have not taken steps to disable System Integrity Protection and your computer is on OS X 10.11 or later, this issue cannot affect you.

Finally, Google offers a solution to this problem: affected macOS users can reboot into Recovery Mode and enter specific commands to remove the Chrome update, which can recover a damaged file system.

chroot /Volumes/Macintosh\ HD # “Macintosh HD” is the default
rm -rf /Library/Google/GoogleSoftwareUpdate/GoogleSoftwareUpdate.bundle
mv var var_back # var may not exist, but this is fine
ln -sh private/var var
chflags -h restricted /var
chflags -h hidden /var
xattr -sw com.apple.rootless “” /var
