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.
