## `NIX_SSL_CERT_FILE` with macOS and the Nix daemon
If you use the Nix daemon, you should also add the following to
`/etc/nix/nix.conf`:
On macOS you must specify the environment variable for the Nix daemon
service, then restart it:
```console
$ sudo launchctl setenv NIX_SSL_CERT_FILE /etc/ssl/my-certificate-bundle.crt
$ sudo launchctl kickstart -k system/org.nixos.nix-daemon
```
ssl-cert-file = /etc/ssl/my-certificate-bundle.crt
```
