It seems to run fine on this machine. However when I try to load it on another machine which has Mac OS X 10.3.3 (Build 7F44) I get the following message. kextload: extension xxx/HelloKernel.kext is not authentic. Could someone tell me the reason for this. Is it due to the version difference or due to some other reason? Thanks Krishna It's almost certainly an error with ownership and permissions of the kext. They probably changed when you copied it to the other machine. Correct those and then it should load.
