Dear Admin,
Just a heads up, I installed HAXM today using the SDK manager through Android Studio using IntelHAXM_1.1.0_for_10.10.dmg
However, the kernal extension is using an outdated signature and hence does not work properly.
i.e. the kextload command yields:
sudo kextload -bundle-id com.intel.kext.intelhaxm
com.intel.kext.intelhaxm failed to load - (libkern/kext) not loadable (reason unspecified); check the system/kernel logs for errors or try kextutil(8).
