Check
Verify the macOS system is configured to disable handoff with the following command:
/usr/bin/osascript -l JavaScript << EOS
$.NSUserDefaults.alloc.initWithSuiteName('com.apple.applicationaccess')\
.objectForKey('allowActivityContinuation').js
EOS
If the result is not "false", this is a finding.
Fix
Configure the macOS system to disable handoff by installing the "com.apple.applicationaccess" configuration profile.
