Question: I'm trying to start an AVD in Android Studio, but it just open a "Splash Screen" (where is written Android), and after, there's no progress.
I searched about it, and I found some discussions about Intel's HAXM ([Android Emulator with HAXM freezes on Mac OS Yosemite](https://stackoverflow.com/questions/26495910/android-emulator-with-haxm-freezes-on-mac-os-yosemite)), I proceeded the installation, but didn't work.

Is there any another config that I should check it out?

That's my AVD settings:   
 API 23   
 Nexus 4   
 1GB (RAM)   
 64MB (VM heap)   
 Graphics: Hardware - GLES 2.0   
 Multi-Core CPU is checked

Intel x86 System Image (to Android 6.0) is installed too

I'm using a MacOS 10.10 (Yosemite) with 4GB (RAM)

Answer: 
Do you have Docker for Mac installed by any chance? I was just facing the exact same issue and stopping Docker fixed the problem...
As I'm not allowed to comment on the above answer, just to add my own experience. Both Docker and minikube - which will admittedly run it's kubernetes containers using docker - need to be stopped for the emulator to work.
