You've just about got it. You just need to add an "OSBundleCompatibleVersion" property into A. It's value will be in the same format as the "CFBundleIdentifier" property. Taken together, these two properties form a binary compatibility version-range. The presence of this property makes kext A a library kext that is acceptable as a library for any other kext (B) asking for a version between "OSBundleCompatibleVersion" and "CFBundleIdentifier", inclusive. Have a look at any of the IOKit Family kexts for an example of this, or have a look at http://developer.apple.com/documentation/DeviceDrivers/Conceptual/ IOKitFundamentals/Families/chapter_7_section_3.html#//apple_ref/doc/ uid/TP0000017/TPXREF104 for a brief discussion of this mechanism. Someone answered me off-line with this solution but this was not enough. The same nice person later added that I may need to use the -r option in kextload to specify where to look for the "master" kernel extension. I haven't tried it yet as I'm doing a lot of things at the same time on different OS releases but I'm optimistic on this one. This email sent to site_archiver@lists.apple.com
