Recently I updated my macOS to High Sierra however this broke my android emulators. Non of them started and logs showed something like:
Failed to open vm 3
Failed to create HAX VM
No accelerator found.
failed to initialize HAX: Invalid argument
As the logs states there is a problem with HAXM, and to be more specific a time for update has come. To solve the issue simply download the latest and greatest version of HAXM and restart your mac.
