## MDM Bootstrap

Machines provisioned via MDM (e.g. Mosyle) use the `mdm-bootstrap.sh` script for
initial activation. This replaces the legacy `activate-user` + `activate`
sequence with the recommended `darwin-rebuild activate` approach.

The MDM bootstrap flow is:

```
systemConfig="$(readlink -f ./result)"
nix-env -p /nix/var/nix/profiles/system --set "$systemConfig"
./mdm-bootstrap.sh
```

See [mdm-bootstrap.sh](./mdm-bootstrap.sh) for details.

# MDM Bootstrap script for nix-darwin Mac builders
#
# This script is intended to be run by an MDM solution (e.g. Mosyle)
# during initial machine bootstrap, after building the nix-darwin
# configuration into a ./result symlink.
#
# It replaces the deprecated activate-user step with the recommended
# darwin-rebuild activate approach.
