Same problem. Console shows: default 22:22:37.780358 +0200 kextd Kext rejected due to system policy: <OSKext 0x7fd3e43168e0 [0x7fff9a194af0]> { URL = "file:///Library/StagedExtensions/Library/Extensions/Soundflower.kext/", ID = "com.Cycling74.driver.Soundflower" } default 22:22:37.780457 +0200 kextd com.Cycling74.driver.Soundflower failed security checks; failing.
