+# Running Kubernetes in Docker (kind) on Macos
+
+I have been using [orbstack](https://orbstack.dev) for over two years now as a drop in replacement for Docker desktop and I have to say it's beyond impressive in terms of performance and feature set. My main motivation to move away from Docker desktop was because it does not support IPv6 on a MacOS. The next thing I tried was Colima but that doesn't support IPv6 either.
