连网收集AddressBookSourceSync/System/Library/Frameworks/AddressBook.framework/Versions/A/Helpers/AddressBookSourceSync.app/ContentI know it is controlled by a LaunchAgent, and I’m told its plist shows that it supports push, which must be why its running, and syncs with MobileMe (or something called ‘dot-mac’), Exchange, and some other things.My worry is I don’t have a MobileMe account, nor a dot-mac whatever. I have not yet logged into Mail, so it should not be looking for Exchange.And now my question is, why does it pop up, asking for permission to access my Keychain every so often and disrupt my work? It refuses to go away when I press ‘cancel’ the first time but takes 3 or 4 ‘cancels’. And then, after a little break, it comes back until I key in my password. Then it appears satisfied. Until the next time!What is it trying to access from my Keychain? And why has it started happening only within the last few weeks? It never used to happen when I first installed Lion. Nor even the update to OS X 10.7.1.Thanks for any illuminating replies.https://discussions.apple.com/thread/3355782timed时钟同步touristd/System/Library/PrivateFrameworks/Tourist.framework/Versions/A/Resources/touristdtouristd is responsible for displaying a New to Mac? notification roughly after 5-10 minutes using macOS Sierra for the first time.Google Chrome允许的：/Applications/Google Chrome.app/Contents/MacOS/Google Chromensurlsessiondnsurlsessiond 是MAC系统后台自动更新线程.关掉即可racoon vpn:/usr/sbin/racoonakdakd是AuthKit（身份验证/授权）框架的一部分
