Hi Andreas! Thanks a lot for the fast answer!!
My OS is in Spanish, so i asume it is cd /Sistema/Librería/Extensions…. but anyway there´s no folder or file called EWSyphonProxyFramebuffer.kext
There is one called EWProxyFramebuffer.kext but it tell me no such a file found. So i can not go further than the second line in the terminal! Any suggestion?
