I've got a problem creating this AVD. I am running OS X Yosemite Version 10.10.5. I've downloaded the android-studio-ide-141.2288178-mac.dmg version. I created a Nexus 5 by cloning the device and keeping the default values. I'm using Lollipop API Level 22 and i've tried armeabi-v7a, x86 and x86_64 Android 5.1 (with Google APIs). When i start the AVD, the image of the actual phone just hangs there with the Android logo appearing. 

When i run the "hello world" app in the developer studio, here are the messages from the AVD window output:
