Enable Private Data in Unified Logs (how-to guide)

Hi All! I finally figured out how to enable (show) private data in Unified Logs in 10.15.3+ now that cmdReporter's private API tricks have been disabled and thought I should share.

You can load this config profile locally with no issue, but this config profile needs to be signed before uploading to Jamf with something like:

/usr/bin/security cms -S -Z "$SIGNING_CERTIFICATE" -i "$UNSIGNED_PROFILE_PATH" -o "$SIGNED_PROFILE_PATH"

Testing:

log stream --predicate '(subsystem == "com.apple.AccountPolicy")'

Unlock a system preference pane, you should not see any "<private>" entries and see full details about user and record type.

And here is the actual profile:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">

Hi @cmdGriggs - does this still work for you?  On ventura it just gave the result below after I manually added the configuration profile on a test machine.  The log entries happened when I unlocked Directory Utility via System Settings > Users & Groups > Network account server > Edit

log stream --predicate '(subsystem == "com.apple.AccountPolicy")'
Filtering the log data using "subsystem == "com.apple.AccountPolicy""
