using the latest XC_Integrated570_v1_0RX_FD51_v1Cert.dmg download, v5.1 set.
New MacBook Pro 15" with touchbar, OS 10.12.4.
Print dialog printer options does not display Fiery Features.. console generates the following error when switching to the XC570 printer-
Library Validation failed: Rejecting '/Library/Printers/Xerox/PDEs/EF772068/EF772068 (FF).plugin/Contents/MacOS/EF772068 (FF)' (Team ID: none, platform: no) for process 'Safari(359)' (Team ID: none, platform: yes), reason: mapped file has no cdhash (unsigned or signature broken?)

Tried to uninstall with the uninstaller in dmg and reinstall.. still got the same console error. During further debugging attempts, I also attempted to uninstall and reset the printing subsystem. Install log does not seem to show any major issues. The only error was-
Apr 11 10:38:34 mac-lap-060 installer[688]: Error getting application status info for file:///Library/Printers/EFI_Temp/ Error Domain=NSCocoaErrorDomain Code=260 "The file “” couldn’t be opened because there is no such file."

Any ideas?
Thanks, Robert
