"Installation Note: The installer requires System Preferences to be launched during the installation process. Do not manually close System Preferences until after clicking Allow in the Security & Privacy Preferences, later in the process.

    CCC notes a macOS 10.15.5 Bug impacts Creating Bootable Backups
    (May 29, 2020 Update: This issue is now addressed in Carbon Copy Cloner 5.1.18.)
    The author of Carbon Copy Cloner has a blog post on a bug in macOS 10.15.5 that impacts creating bootable backups. Here's a clip:
    "A bug in macOS 10.15.5 impacts bootable backups, but we've got you covered
    Early last week we discovered an APFS filesystem bug in a beta of macOS 10.15.5. The technical details of the bug are laid out below, but the short version is that we're no longer able to use our own file copier to establish an initial bootable backup of a macOS Catalina System volume. To be very clear - existing backups are unaffected, and this has no effect on CCC's ability to preserve your data, nor any effect on the integrity of the filesystems on your startup disk or your backup disk. The impact of this bug is limited to the initial creation of a bootable backup... "
    The full blog has more details & tips on "Creating bootable backups in a post-10.15.5 world".
    macOS 10.15.5, Safari 13.1.1, Security Update 2020-003 for Mojave & High Sierra
    Available via software update, or the download pages below.
    Long list of fixes (some under "Enterprise Content") in the macOS 10.15.5 release notes.
    (macOS 10.15.5 also adds battery health management for Mac notebooks.)
    Here's the article on security fixes in macOS 10.15.5 and Security Updates 2020-003 for macOS 10.14.6 & 10.13.6, and article on security fixes in Safari 13.1.1. (Safari 13.1.1 available for macOS 10.14.6/10.13.6, included in macOS 10.15.5.)

    Note: For 10.15.5 & Security Update 2020-003 - "Major new releases of macOS are no longer hidden when using the softwareupdate(8) command with the --ignore flag". (Some users did that to prevent update nags.)

    FYI: If you use Nvidia's web graphics drivers for 10.13.6, the Security Update new build number requires a driver update.
    Update - See above May 29th Nvidia Graphics Driver Update for 10.13.6.

    Little Snitch 4.5.2 (Bug and Security Fix)
    May 26th version 4.5.2 update to Little Snitch. (For macOS 10.11 or later.)
    Here's info on fixes from the release notes:
    • Fixes a local privilege escalation issue (CVE-2020-13095). By exploiting this vulnerability, users logged in to the computer can gain root privileges, but they cannot circumvent System Integrity Protection. Details about this issue will be revealed later.

    • Fixes an issue in the connection alert causing the user's host/domain choice to be ignored under some rare circumstances.
    The release notes also included this statement from the developer in red:
    "We highly recommend to update to this version soon because it fixes a possible privilege escalation"
    DisplayLink v5.2.4 USB Software Update for macOS Catalina & Mojave
    The DisplayLink macOS USB Software page has v5.2.4 software for macOS Catalina and Mojave. (Software for older macOS versions are down the main page under "Legacy Drivers".)
    Here's their note on macOS 10.15 Catalina and DisplayLink kernel extension:
    "Information about macOS 10.15
    Some users updating to 10.15 have found their DisplayLink devices have stopped working. 5.2 software is designed to run on Mac OS 10.15, but the OS can disable our kernel extension during the update. Please check the kernel extension is enabled and screen recording is also enabled, to ensure DisplayLink enabled devices continue to work when migrating to 10.15."
