Managed to get it working with avaddon's solution as well. Though my popup didn't have allow, it just had an Okay and after I pressed it, nothing changed.  Now I get: "Extension with identifiers com.razer.common.razerhid not approved to load. Please approve using System Preferences." For me the pop up said okay or open system preferences. You have to go into System Preferences, Security and Privacy, and click allow there for it to work.
