First of all, it's only for Developer ID App, not for Mac Store App.We have legacy Cocoa Application A. We don't want to embed the System Extensions in it because the changing would be too much. Instead, we're thinking of developing the other container App B to embed the System Extensions, and adding B to A as Helper App (like Build Phase->Copy Bundle Resources). Then A application can simply launch B application to enable the System Extensions. I want to know if it's actually feasible? Could it pass Notarization? Thanks,Xin

In System Preferences -> Sharing, we can see and change Computer Name, like "Bob's Macbook Pro", the system will convert it to Local Hostname like "Bobs-Macbook-Pro". Is there any documents describe how to convert the special characters in Computer Name to Local Hostname? Thanks,xhu
