qemu-system-i386 quit unexpectedly when starting AVD (Android Virtual Device) on a Mac (illegal instruction 4)

Question

I installed Android Studio on my Mac (Macbook Pro, August 2017, OSX 10.12.4), then started up, created a hello world project and created an AVD (Android Virtual Device, Nexus 5) to run my project on it.

The error shows when I try to run my project on the simulator (pressing the play button) or when I try to start up the emulator itself.

Here's a screenshot of the error:

Answer 1

Disabling / Uninstalling CylancePROTECT solved this issue for me.

sudo launchctl remove com.cylance.agent_service

The same software was also preventing me from compiling go programs.

Some memory protection is at the source of the problem. Here is the relevant article for some fine tuning of CylancePROTECT that could resolve the issue with uninstalling completely the software: runtime: bsdthread_register fatal error (CylancePROTECT)

Answer 2

I solved it by go to ADV manager -> Select Virtual Device -> edit icon -> Select Graphics to Software GELS-2.0
