Vircadia has two different installers. The Client Installer comes with everything you need to view and interact with Vircadia’s content and users. However, you are unable to host content using this installer. The Client + Sandbox Installer has everything the client installer does, but it also enables you to host your own content and share it with the world.

Windows 10, 64-bit or MacOS High Sierra (10.13)
8GB+ RAM i5
A wide range of Nvidia, AMD, and Intel graphics cards are supported
In addition, your network must have enough internet bandwidth to run Vircadia:

If you are hosting a domain on your Sandbox, you need to add 10 Mbps upload for each user you want to concurrently visit your domain.
We also run on Linux devices; however, we do not publish an installer for Linux machines. To use Vircadia on Linux, you will need to build the application from our code base. For more information, see our Linux Build Guide.

If you intend to use Vircadia in VR mode with a HMD, ensure that Steam VR is also installed on your system before launching Vircadia.
Once you’ve downloaded the installer, you’re ready to install Vircadia. The process will be different based on your operating system:

Drag Vircadia to the Applications folder.
Open System Preferences > General.
Next to the warning indicating that Interface is blocked, click ‘Open Anyway’.
Confirm that you want to open the application.
At this point, Interface will open and you will be able to log in and begin exploring the metaverse.
If you’re facing problems when you load Interface and Sandbox, you can try performing a clean install. A clean install removes multiple files and settings that you may need once you install Vircadia again.
