Validated the issue again with the latest 26A5421a beta version and issue did not resolve.
We collected the system logs and noticed that com.apple.configuration.app.settings grants Accessibility but not PostEvent access on macOS 27 Golden Gate.
The Blueprint and declarations are successfully deployed to the device. macOS displays an “Allow / Not Allow” managed-access prompt for each application.
After selecting Allow, both applications immediately receive the older Accessibility dialog stating that the application would like to control the Mac, with Open System Settings / Deny options.
The system log indicates that the managed declaration is successfully authorizing kTCCServiceAccessibility.
Example: Using managed_overrides value:
service=kTCCServiceAccessibility,
client=...,
auth_value=2,
flags=0x20
Handling access request to kTCCServiceAccessibility ...
However, when either application attempts to create a CGEventTap, TCC evaluates kTCCServicePostEvent separately:
com.apple.accessibility.universalAccessAuthWarn
The resulting PostEvent records are ultimately set to denied:
Update Access Record:
kTCCServicePostEvent for ...
to Denied (System Set)
Update Access Record:
kTCCServicePostEvent for com.verdasys.DgSessionSvc
to Denied (System Set)
Questions
Is com.apple.configuration.app.settings intended to authorize only kTCCServiceAccessibility, without authorizing kTCCServicePostEvent?
Is a separate DDM setting required for PostEvent access?
Is the additional legacy Accessibility prompt expected after the user has already selected Allow in the managed-access prompt?
