Note

From Genymotion Desktop 3.3.0 onward, it is possible to switch to QEMU hypervisor instead of VirtualBox. Also, QEMU utilizes Hypervisor which is installed by default on macOS, so we strongly recommend using QEMU instead of VirtualBox hypervisor when possible.

Important

VirtualBox hypervisor is not available on mac M.

mac M series

Compatibility with mac M series has been added with Genymotion Desktop 3.4.0. If you tried to install and run Genymotion Desktop 3.3.3 or lower, you will need to purge it before installing Genymotion 3.4.0.

For more information, please refer to Apple Mac M series support.

macOS has just been upgraded

Upgrading macOS often breaks VirtualBox. If an error occurs after the upgrade, try re-installing or upgrading VirtualBox to the latest stable version.

macOS security blocked VirtualBox kernel installation

This issue may be due to security restrictions in macOS which blocks VirtualBox modules installation.
