My Mac book won't let me install `hamachi` or use some programs. The problem I tried to install says `hams.kext` or `hamns.kext` was installed incorrectly and told me to reinstall it, I tried looking into the web but no one has the same problem. How do I reinstall `hams.kext`, `Hamns.kext`? I waited 5 days for a response on my other article I made, but no response.
