For /var/log/system.log full of errors like these ones:
kernel[0]: Sandbox: com.apple.Addres(XXXXX) deny(1) network-outbound /private/var/run/mDNSResponder
com.apple.AddressBook.InternetAccountsBridge[XXXXX]: dnssd_clientstub ConnectToServer: connect()-> No of tries: 1
com.apple.AddressBook.InternetAccountsBridge[XXXXX]: dnssd_clientstub ConnectToServer: connect() failed path:/var/run/mDNSResponder Socket:4 Err:-1 Errno:1 Operation not permitted
How to fix it?
Require SIP disabled and root access:
- update
/System/Library/Sandbox/Profiles/application.sb(see below) - delete
/Users/mems/Library/Containers/com.apple.AddressBook.InternetAccountsBridge(will be regenerated based on the updated sandbox profile) - kill all processes named
com.apple.AddressBook.InternetAccountsBridge - restart
Contact.apporMail.app
To update application.sb:
(unless
(or (entitlement "com.apple.security.network.client")
(entitlement "com.apple.security.network.server")
(entitlement "com.apple.security.print"))
(deny network-outbound (literal "/private/var/run/mDNSResponder")))
to
(unless
(or (entitlement "com.apple.security.network.client")
(entitlement "com.apple.security.network.server")
(entitlement "com.apple.security.print")
(equal? (param "application_bundle_id") "com.apple.AddressBook.InternetAccountsBridge"))
(deny network-outbound (literal "/private/var/run/mDNSResponder")))
Contact.app will still a bit unresponsive (spinning beach ball) when edit some contacts, but errors will stopped.
