Thanks franctastic. From the beginning it has been a hell. In my case I have the macOs High Sierra Version 10.1.3.4 beta (17E160e). The computer was hanging randomly, something unusual in macOS. Until I've realized that is Razer the problem, I lost a week trying to find what's going on. Yesterday I discovered, and finally, I uninstalled the botched driver. Razer, are your programmers qualified for macOs? If you do not answer, is it because you do not want or because you have become deaf?
