I am using LaunchDaemons to execute daemon on Mac OS 10.5
I am using IOKit in my daemons

But while it executing daemons it give error in IOServiceOpen API at
the time of boot

So which services i have to add with MachServices property key

I think you're a bit in the weeds here.  Are you trying to connect to a service or vend a service?  The MachServices property is only relevant if you're trying to vend a Mach service.  You don't need to put anything special in your launchd property list file to just connect to a service.

Does this stuff work if you load your daemon post boot?  My best guess, given the info above, is that you're trying to connect to an I/O Kit service early in the boot process, and the service hasn't got around to being registered yet.
