I'm on a new MacBook Pro M3 and installed Azure CLI using Homebrew as follows:
brew install azure-cli
brew update && brew install python@3.11 && brew upgrade python@3.11
brew link --overwrite python@3.11
When I run az bicep --help it works fine
When I run az bicep version or any other command like az bicep upgrade I get this:
The command failed with an unexpected error. Here is the traceback:

Azure CLI Bicep throwing error on MacBook M3
The error you encountered is due to an issue with the Bicep executable file that the Azure CLI is trying to run. Specifically, the error message Exec format error indicates that the file format of the Bicep executable is not compatible with your Mac system architecture.
To resolve this issue, you can try uninstalling and reinstalling the Azure CLI using the below commands.
brew uninstall azure-cli
rm -rf ~/.azure/bin/bicep
brew update && brew install azure-cli
