To find specific versions or view all available platforms and architectures, visit the [releases page](https://github.com/vmware-tanzu/pinniped/releases/). ### Gatekeeper If you are using macOS, you may get an error dialog when you first run `pinniped` that says `“pinniped” cannot be opened because the developer cannotbe verified`. Cancel this dialog, open System Preferences, click Security & Privacy, and click the Allow Anyway button next to the Pinniped message. Run the command again and another dialog appears saying `macOS cannot verify the developer of “pinniped”. Are you sure you want to open it?`. Click Open to allow the command to proceed. ## Install a specific version via script For example, to install v0.4.1 on Linux/amd64: ```sh curl -Lso pinniped https://get.pinniped.dev/v0.4.1/pinniped-cli-linux-amd64 \ && chmod +x pinniped \ && sudo mv pinniped /usr/local/bin/pinniped ``` *Next, [install the Concierge]({{< ref "install-concierge.md" >}})!*
