# Objective

Without the `font-kit` feature, `MacPlatform` silently substitutes
`gpui::NoopTextSystem`, which accepts fonts and resolves font ids but
rasterizes every glyph to an empty bitmap.

I hit this with the `component_preview` example
https://github.com/zed-industries/zed/pull/59241.

## Solution

Log a warning at startup in `MacPlatform::new()` when falling back to
`NoopTextSystem`. Skipped in headless mode, where no text is expected to
render and the fallback is a reasonable configuration.

## Testing

Checked as part of https://github.com/zed-industries/zed/pull/59241
