## Issue Addressed Resolves https://github.com/sigp/lighthouse/issues/2763 ## Proposed Changes - Add a workflow which tests that local testnet starts successfully - Added `set` option into the scripts in order to fail fast so that we can notice errors during starting local testnet. - Fix errors on MacOS - The redirect `&>>` is supported since bash v4 but the version bundled in macOS(11.6.1) is v3. https://github.com/sigp/lighthouse/pull/2919/commits/a54f119c9b1839fd0909792d219858e727e120a2
