why my genymotion block in the start the virtual device?

Genymotion Desktop can block a virtual device start on macOS when QEMU/VirtualBox, local ports, firewall rules, or an unsupported environment conflict. If you are on Mac M, VirtualBox is not available, and QEMU should be used instead: macOS - Unable to start the Virtual Device.

Common causes:

  • macOS firewall blocks local connections
  • Another app uses a required port, especially 6379 for Redis
  • You are running Genymotion in a VM, server, or cloud instance, which is not supported
  • You are on Mac M with an old legacy install, or on Mac M4 with macOS Sequoia 15.2 and an outdated version

What to check: 1. Switch to QEMU on macOS if you were using VirtualBox. 2. Verify ports 5555, 6379, 24297, 24810, 24800, 25000, and 22468 are free. 3. Stop Redis if needed with brew services stop redis. 4. Make sure macOS firewall allows local connections. 5. Update Genymotion Desktop if you are on Mac M4 with Sequoia 15.2.

If you want, tell me your Mac model, macOS version, and the exact error message, and I’ll narrow it down.
