Hi Brad, I believe the CHUD kexts have similar requirements to your kext - we want our kexts to be loaded at boot time (actually at some point we will change this so that they are loaded on demand so as not to waste wired memory, but for now...) but don't actually match to any hardware device. Our Info.plist contains the following relevant fields (especially note the IOProviderClass and IOResourceMatch fields). Note that you do not to specify the OSBundleRequired characteristic to get the kexts to load at boot time (this only ensures that they will load even in safe mode). The tutorial at http://developer.apple.com/documentation/Darwin/Conceptual/howto/ kext_tutorials/hello_iokit/hello_iokit.html talks about some of these fields in more detail. <key>IOKitPersonalities</key> <dict> <key>FirstPersonality</key> <dict> <key>CFBundleIdentifier</key> <string>com.apple.iokit.CHUDUtils</string> <key>IOClass</key> <string>CHUDUtils</string> <key>IOMatchCategory</key> <string>CHUDUtils</string> <key>IOProviderClass</key> <string>IOResources</string> <key>IOResourceMatch</key> <string>IOKit</string> <key>IOUserClientClass</key> <string>CHUDUtilsUserClient</string> </dict> </dict> <key>OSBundleLibraries</key> <dict> <key>com.apple.kernel.bsd</key> <string>6.0</string> <key>com.apple.kernel.iokit</key> <string>6.0</string> <key>com.apple.kernel.mach</key> <string>6.0</string> </dict> -- Nathan Slingerland Architecture and Performance Group Apple Computer, Inc.

I've got the following set in the Info.plist OSBundleLibraries com.apple.kernel.bsd = 1.1 com.apple.kernel.mach = 1.1 com.apple.kernel.libkern = 1.1 OSBundleRequired = Root I have tried using kextcache and it reports no errors, it's just after I reboot the kext doesn't. I have tried the simple generic kext as well and it doesn't work, so can someone help? I need to be able to support 10.2 and later, so I am still using Project Builder... Thanks.
