> I would like to know about applying filter scheme to work for HFS and Non-HFS volumes. Is it possible? > The current code as from SampleFilterScheme that works with HFS+ volumes: Unfortunately, the content hin in this context doesn't really mean what you think. Basically, it's exposing the data that was written into the partition map, which basically has nothing to do with the actual filesystem written to a particular partition. > What should be changed here to support NTFS or FAT as well with HFS? Nothing really, at least in functional terms. I haven't tested it recently, but I believe if you were to simply erase one of your partitions and replace it with FAT32, everything would continue to work as is. DiskUtility might be updating the partition map, in which case the content hint would change, but nothing in the system requires that. That's easy to confirm by writing the new filesystem using the command line. > Or to support NTFS and FAT devices do i need to write some other Kernel module and not use IOMedia. In general, I can't think of any reason why you'd need to write an IOMedia driver to support other filesystems.

AuthorizationRightSet unexpectedly fails on os x 10.9 DP1; authd logs strange error
by Michael Ritter 24 Jul '13

24 Jul '13

Our preflight installer script needs to add an authorization right. This worked on OS X 10.4-10.8 but suddenly stopped working on OS X 10.9 DP1. AuthorizationRightSet() fails with -60005 (errAuthorizationDenied), and the following error message is logged by authd: "Jul 20 07:20:15 Testers-Mac.local com.apple.authd[66]: server[584]: AuthorizationRightSet Denied process identifier not found, missing code signature." Our installer runs as superuser. Executing the below code from a command line program by root fails in the same manner. Here's the source code: int SetAuthRight() { OSStatus status; AuthorizationRef auth; status=AuthorizationCreate(NULL, kAuthorizationEmptyEnvironment, kAuthorizationFlagDefaults, &auth); if(status!=noErr){ syslog(LOG_ERR, "AuthorizationCreate failed: %d.", (int)status); return -1; } status=AuthorizationRightSet(auth, "mycompany.myapp.auth", CFSTR(kAuthorizationRuleAuthenticateAsAdmin), CFSTR("my_display_message"), NULL, NULL); AuthorizationFree(auth, kAuthorizationFlagDefaults); if(status!=noErr){ syslog(LOG_ERR, "AuthorizationRightSet failed: %d.", (int)status); return -1; } return 0; } Thanks in advance.
