Hi, sir.
What is described in Apple's official document The IOKitPersonalities key is as follows:
CFBundleIdentifier—The bundle ID of your driver
IOClass—The Apple class containing the base behavior
IOUserClass—The name of your custom service class
IOUserServerName—The bundle identifier of your driver
IOProviderClass—The class that your service requires as its provider object
my question is
Is the value of CFBundleIdentifier and IOUserServerName the same?
