# macOS
This is the configuration for the `proj-servo/macos` worker type.
These macOS workers are configured with SaltStack in [agentless] mode.
[agentless]: https://docs.saltstack.com/en/getstarted/ssh/index.html
Either run `./salt-ssh`
to automatically install `salt-ssh` in `mach`s existing Python virtualenv,
or install `salt-ssh` through some other mean and run in from this directory.
```sh
cd etc/taskcluster/macos
./salt-ssh '*' test.ping
./salt-ssh '*' state.apply test=True
```
## Troubleshooting
SSH into `servo-tc-mac1.servo.org`.
`generic-worker` logs are in `less /Users/worker/stderr.log`.
If the worker seems stuck but nothing seems wrong in the log,
try running `launchctl stop net.generic.worker`.
(It is configured to restart automatically.)
This issue is tracked at
[generic-worker#133](https://github.com/taskcluster/generic-worker/issues/133).
## (Re)deploying a server
* Place an order or file a ticket with MacStadium to get a new hardware or reinstall an OS.
* Change the administrator password to one generated with
`</dev/urandom tr -d -c 'a-zA-Z' | head -c 8; echo`
(this short because of VNC),
and save it in the shared 1Password account.
* Give the public IPv4 address a DNS name through Cloudflare.
* Add a correponding entry in the `config/roster` file.
* Log in through VNC, and run `xcode-select --install`
## Taskcluster secrets
This SaltStack configuration has a custom module that uses Taskclusters
[secrets service](https://tools.taskcluster.net/secrets/).
These secrets include an [authentication token](
Youll need to authenticate with a Taskcluster client ID
that has scope `secrets:get:project/servo/*`.
This should be the case if youre a Servo project administrator (the `project-admin:servo` role).
## Workers client ID
Workers are configured to authenticate with client ID
[`project/servo/worker/macos/1`](
https://tools.taskcluster.net/auth/clients/project%2Fservo%2Fworker%macos%2F1).
This client has the scopes required to run tasks for this worker type.
