Question

Is there some way I can programmatically change the users account image on OSX?

I know I can retrieve it, but can it be changed like apple does on the account page in the settings app?

Answer 1

You can use the Address Book framework. You need to use the me method to get the record for the current user, and then the setImageData: method to set the user’s image:

#import <AddressBook/AddressBook.h>

@implementation YourClass
- (void)setUserImage:(NSImage*)anImage
{
    ABPerson* me = [[ABAddressBook addressBook] me];
    [me setImageData:[anImage TIFFRepresentation]];
}
@end

There’s more detail here in the docs.
