Answer 1

I just ran into this problem as well. I'm running Yosemite so the downgrading solution isn't pertinent. Eventually I decided to try running the silent_install.sh that's in the same dir as HAXM installation, and it worked.

Details

1. Open terminal window. (/Applications/Utilities/Terminal)
2. sudo ~/Library/Developer/Xamarin/android-sdk-macosx/extras/intel/Hardware_Accelerated_Execution_Manager/silent_install.sh
3. when prompted, enter sudo password.
4. wait a minute - says "Silent installation Pass!".

To verify success:

1. Open Google Android Virtual Device (AVD) manager.
2. Create a virtual machine with x86 or x86_64 as architecture.
3. Start that virtual machine - says "HAX is enabled", and Android Emulator window opens showing the emulated device.
