    Be cautious with upgrading if you run enterprise-level DLP software, as well, like Broadcom/Symantec Data Loss Prevention. Upgrading to 10.15.7, or deploying brand new Macs with it, has broken the DLP agent software and Broadcom is apparently scrambling to get a version out that works with what changed since 10.15.6 (which will require server upgrades and all that fun stuff).

    This OS point release is the first in years that has been problematic for me. What I mean is, the install finished and rebooted and then, I was stuck at the login screen. When I attempted to login (to any account), the OS would crash and reboot.
    I had to boot into Recovery mode, and both run Disk Utility and also reboot (and clear PRAM/NVRAM, not once; but twice) and this resolved the issue, allowing the update install to complete. Just something to be aware of when updating.
