why is Genymotion blocked when starting the virtual device?

✅ YES — on macOS, the most common causes are a firewall blocking local ports, a port conflict, or using an unsupported setup like a VM or server. QEMU is the recommended hypervisor on macOS, and on Mac M series VirtualBox is not available.

  • Genymotion Desktop uses local TCP ports such as 5555, 6379, 24297, 24810, 24800, 25000, and 22468. If another app is using one of them, the virtual device may not start.
  • Redis often conflicts on port 6379, so stopping it can help: brew services stop redis
  • Genymotion Desktop is not supported inside a virtual machine, on a server, or in a cloud macOS instance.
  • If you are on Mac M and upgraded from Genymotion Desktop 3.3.3 or lower, you need to purge the old install before upgrading.
