To use option key under macOS as Meta key use the option
`option_as_alt` and set it to `"Both"`.

This is the example for the newer Toml file format.

```toml
# ~/.alacritty.toml
[window]
option_as_alt = "Both"
```

And this is the older YAML format.

```yaml
# ~/.alacritty.yml
window:
  option_as_alt: Both
```
