I've implemented a VPN app for OS X, and sent it for testing to my co-workers.
While it's working fine for the most of them, 2 people weren't able to run it - and got the error
plug-in sdk "com.apple.networkextension.packet-tunnel" not registeredI also notice they have a lot of logs with the errors
System Policy: deny(1) file-write-create /System/Library/Caches/com.apple.coresymbolicationdcom.apple.xpc.launchd[1]: (com.apple.coresymbolicationd) Service only ran for 0 seconds. Pushing respawn out by 10 seconds.From what I read in a lot of topics here, that means the OS might be corrputed, so I asked them to reinstall the OS, and it really did help, and now they are able to run my app.
Before asking them to reinstall, I tried a lot of things, but none of them helped.
So my question is - what should I do when I publish my app at the App Store? What if some client would get the same error?
I can't ask the clients to reinstall their OS..
