问题
I recently updated my Macbook pro to Mac OS High Sierra. Now I'm running into an issue where I can no longer start the emulator in Android Studio.
The warning /dev/kvm is not found. is shown. When I tried to start the emulator I get the following error:
I tried different versions of Intel HAXM from the SDK manager and standalone, reinstalling Android Studio and completely removing all configurations, still the same issue..
回答1:
- Go to: System Preferences > Security & Privacy > General
There should be a message like “System software from developer xxx was blocked from loading.”
- Click Allow

It seemed to be an Intel HAXM issue. I resolved it by completely removing Intel HAXM.
Then I followed this guide, which basically makes you edit the install script of HAXM so the silent installation will work on Mac OS High Sierra.

To use VM acceleration on a Mac, you must install the Intel HAXM kernel extension to allow the emulator to make use of CPU virtualization extensions. Android Studio requires Mac OS X 10.8.5 or higher, up to 10.11.4 (El Capitan) Mac OS X; the kernel extension is compatible with Mac OS X 10.6.0 and higher.
To install the Intel HAXM kernel extension, follow these steps:
- Open the SDK Manager.
- Click the SDK Update Sites tab and then select Intel HAXM.
- Click OK.
After the download finishes, execute the installer. For example, it might be at this location:
sdk/extras/intel/Hardware_Accelerated_Execution_Manager/IntelHAXM_version.dmg.
To begin installation, in the Finder, double-click the IntelHAXM.dmg file and then the IntelHAXM.mpkg file.
Follow the on-screen instructions to complete the installation.
After installation finishes, confirm that the new kernel extension is operating correctly by opening a terminal window and running the following command:
kextstat | grep intel
You should see a status message containing the following extension name, indicating that the kernel extension is loaded:
com.intel.kext.intelhaxm

I found the answers provided by @AresDev & @ShubhamJain to be super helpful for the uninstallation & re-installation of HAXM, but in my case it still didn't resolve the /dev/kvm not found errors I was seeing. My Mac OS High Sierra was blocking the AVD / Intel extensions from running correctly, and I had to Allow it under System Preferences > Security & Privacy > Allow.
However, the Allow button doesn't respond in some situations! I had to quit Google Chrome, before could click Allow, as described in these posts: "Github Karabiner Elements Issues"
