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:
