Okay, let me know how this works for you:

1. Quit Local if it’s running
2. Open Terminal
3. Run:

```auto
alias local-docker-machine="/Applications/Local\ by\ Flywheel.app/Contents/Resources/extraResources/virtual-machine/vendor/docker/osx/docker-machine"

```

1. Run (wait for it to finish before moving onto step #5):

```auto
local-docker-machine stop local-by-flywheel; rm -rf ~/.docker/machine/certs; local-docker-machine create local-cert-gen; local-docker-machine start local-by-flywheel; local-docker-machine regenerate-certs -f local-by-flywheel; local-docker-machine rm -f local-cert-gen;

```

1. Re-open Local
