## Quick Checklist

| # | Check | Why it matters | How to verify |

|---|-------|----------------|---------------|

| 1 | **Hardware specs** | Genymotion relies heavily on CPU & RAM. | `System Information` → *CPU, RAM, GPU* |

| 2 | **Host OS** | We only support Windows 10/11, macOS 13+, and recent Linux distros (Ubuntu 22.04+, Fedora 36+). Windows 7 is not supported. | `Win + R → winver` (or `macOS` → About This Mac). |

| 3 | **Virtualization** | VirtualBox/Genymotion needs VT‑x/AMD‑V and nested paging. | In BIOS/UEFI → “Intel VT‑x” or “AMD‑V” enabled. |

| 4 | **Genymotion version** | Older desktop builds may have bugs fixed in newer releases. | `Genymotion` → `Help → About` |

| 5 | **Android 11 image** | Some legacy images have known performance regressions. | `Genymotion` → `Device → Manage Devices → Android 11` |

| 6 | **CPU/GPU usage during run** | High usage can throttle the VM. | Task Manager (Windows) / Activity Monitor (macOS) or `htop` (Linux) |

## Step‑by‑Step Troubleshooting

1. **Confirm host OS compatibility**

- *If you’re on Windows 7, you’re out of luck – upgrade to Windows 10/11.*

- For macOS or Linux, make sure you’re on a supported release.

2. **Check virtualization settings**

- Restart your PC and enter BIOS/UEFI.

- Ensure *Intel VT‑x* (or AMD‑V) and *nested paging* (or “nested virtualization”) are turned on.

- Save and reboot.

3. **Upgrade Genymotion Desktop**

- Go to *Help → Check for Updates* or download the latest installer from the website.

- Version 3.9.0 (or newer) includes performance improvements, especially for ARM‑64 images.

4. **Use the ARM‑64 Android 11 image**

- If you’re still on an x86 image, consider switching to the ARM‑64 variant.

- ARM images are now fully supported on Genymotion Cloud and Desktop (see our 2025 update). They often run more smoothly on modern CPUs with hardware‑accelerated ARM support.

5. **Allocate sufficient RAM & CPU cores**

- In *Settings → Devices*, set the VM’s RAM to at least **4 GB** (8 GB if you have it).

- Assign **2–4 CPU cores** to the VM.

- Don’t over‑allocate; leave enough headroom for your host OS.

6. **Disable unnecessary background apps**

- Close other heavy programs (IDE, browsers, media players).

- On Windows, use `Task Manager` → *Processes* → sort by CPU/RAM and end non‑essential tasks.

7. **Enable “Hardware Acceleration” for graphics**

- In the device settings, ensure *“Enable 3D acceleration”* (or “Hardware‑accelerated graphics”) is ticked.

- If you’re on Windows, make sure your GPU drivers are up‑to‑date (Intel, NVIDIA, AMD).

8. **Check logs for freeze causes**

- `Genymotion` → *Help → Show Log*.

- Look for repeated “Out‑of‑memory” or “CPU overload” messages.

- If you see errors like `Could not start ADB`, reinstall the ADB drivers.

9. **Try the Cloud version**

- If local resources are limited, spin up an Android 11 VM on Genymotion Cloud.

- Cloud instances use powerful GPUs and more RAM than most desktops.

10. **Reinstall Genymotion (last resort)**

- Uninstall, delete residual folders (e.g., `%APPDATA%\Genymobile`), and reinstall fresh.

## Quick Tips

- **Use 64‑bit host OS** – 32‑bit Windows is not supported for Genymotion.

- **Enable Hyper‑V (Windows)** – Genymotion works best with Hyper‑V enabled.

- **Keep your GPU drivers current** – Especially if you’re using the “Hardware‑accelerated graphics” option.

- **Avoid running multiple VMs simultaneously** – Each VM consumes significant resources.
