* Re-use VMDirectory.running() in "tart get"

 *Cirrus Runners* is the fastest way to get your current CI workflows to benefit from Apple Silicon hardware. No need to manage infrastructure or migrate to another CI provider.

+Max Lapides, Senior Mobile Engineer at [Tonal](https://www.tonal.com/).

+> Previously, we were using the GitHub‑hosted macOS runners and our iOS build took ~30 minutes. Now with Cirrus Runners, the iOS build only takes ~12 minutes. That’s a huge boost to our productivity, and for only $150/month per runner it is much less expensive too.

 ## Configuring Cirrus Runners
 
 Configuring Cirrus Runners for GitHub Actions is as simple as installing [Cirrus Runners App](https://github.com/apps/cirrus-runners).
