Some sort of "synchronizable" setting?

(__bridge id)kSecAttrSynchronizable: (__bridge id)kCFBooleanTrue

It seems like the synchronizationMode can be directly set if you create a SAMKeychainQuery, just use (as an example):

+ (BOOL)setPassword:(NSString *)password forService:(NSString *)serviceName account:(NSString *)account error:(NSError *__autoreleasing *)error {
	SAMKeychainQuery *query = [[SAMKeychainQuery alloc] init];
	query.synchronizationMode = SAMKeychainQuerySynchronizationModeNo;
	query.service = serviceName;
	query.account = account;
	query.password = password;
	return [query save:error];
}
