i create a systemextension which bundleshortversion is 2.0. And my macos has install the version of 1.0. when i cover the 2.0 extension to the 1.0, and then do activiationRequestForExtionson, although it success at last,request(:actionForReplacingExtension:withExtension:) is never called. when i look into "sysextd" 's log . I find it always call alreadyActive install of requestAppReplaceAction. from https://developer.apple.com/documentation/systemextensions/installing_system_extensions_and_drivers , i know macos will call request(:actionForReplacingExtension:withExtension:) if buidleshortversion or bundleversion is different, so is there any possible reason on my case?
