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.
