# Doppler CLI Unsupported architecture aarch64 install script Apple Silicon

## Whats going on

Running the Doppler CLI install script ((curl -Ls https://cli.doppler.com/install.sh || wget -qO- https://cli.doppler.com/install.sh) | sh) fails with: ERROR: Unsupported architecture 'aarch64'. Expected the script to install Doppler, including on Apple Silicon machines.

## What actually fixes it

Apple Silicon support was added in Doppler CLI v3.23.0. If you hit the "Unsupported architecture aarch64" error, you are running an older install script, re-download and run the current install script (or install v3.23.0+) and it proceeds. The original blocker was Go itself, which only gained macOS arm64 builds in Go 1.16.
