Apple has just released an update to XProtect Remediator security software for Macs running Catalina or later, bringing it to version 87. This is the first update this year, since 86 released on 8 December 2022, because of the seasonal break.

Apple doesn’t release information about what security issues this update might add or change, and this update doesn’t add any further scanning modules.

You can check whether this update has been installed by opening System Information via About This Mac, and selecting the Installations item under Software.

A full listing of security data file versions is given by SilentKnight, LockRattler and SystHist for El Capitan to Ventura available from their product page. If your Mac has not yet installed these updates, you can force them using SilentKnight, LockRattler, or at the command line.

Those using Content Caching servers might be in luck this time: mine seems to have worked properly so far.

If you want to install this as a named update in SilentKnight, its label is XProtectPayloads_10_15-87.

I have updated the reference pages here which are accessed directly from LockRattler 4.2 and later using its Check blog button.

I maintain lists of the current versions of security data files for Ventura on this page, Monterey on this page, Big Sur on this page, Catalina on this page, Mojave on this page, High Sierra on this page, Sierra on this page, and El Capitan on this page.
