I used the reverse DNS for KEXT CFBundleIdentifier property during the development phase. Now I'm wondering if I have to register my KEXT name (so the reverse-DNS + some identifier)? << I'm asking this as e.g. on Windows it is needed to register the Reparse Point tag with Microsoft. So, just to be sure. There's no registration of KEXTs for Mac OS X. But CFBundleIdentifiers do need to be unique. The naming convention if you're an I/O Kit driver is "com.yourcompany.driver.someIdentifier". You get to choose what someIdentifier is, so long as it's unique within your product line.
