目标C：如何以编程方式检查OS X中的来宾登录权限首选项

Question

I am able to get a list of all users ( see: Get all Users on OS X ), but how can I identify that a guest user is allowed on Mac OS X.

We can toggle guest login permission in "Users and Groups" in "System Preferences". Can I check this setting programmatically?

Answer 1

We can read GuestEnabled key from com.apple.loginwindow.plist file stored in library preferences.

 NSMutableDictionary *plistDict = [[NSMutableDictionary alloc]initWithContentsOfFile:[NSString stringWithFormat:@"/Library/Preferences/com.apple.loginwindow.plist"]];


BOOL isEnabled =  [[plistDict objectForKey:@"GuestEnabled"] boolValue];
