Older Xcode versions are removed from base images over time. If your queue has an Xcode version pinned that is no longer available, a warning is displayed on the queue list and queue settings pages: "Xcode {version} is no longer available for this macOS version. Your agents may fail to start until you update the base image of your queue." To resolve the warning, navigate to the queue's **Base image** settings and select an available Xcode version.

### Docker support

macOS hosted agents do not include a running Docker daemon. Pipeline jobs that require Docker daemon access, such as `docker build` or `docker run`, will fail unless they connect to a Docker daemon that you provide.

For Docker image builds, use [Linux hosted agents](/docs/agent/buildkite-hosted/linux) with [remote Docker builders](/docs/agent/buildkite-hosted/linux/remote-docker-builders), or run the job on [self-hosted agents](/docs/agent/self-hosted) where you control the Docker installation.

> Three macOS Tahoe versions are available, each with a unique set of Xcode versions. [Tahoe (26.3.1)](/docs/agent/buildkite-hosted/macos#macos-tahoe) includes older Xcode versions, because certain older Xcode versions are incompatible with newer Tahoe base images. [Tahoe (26.5)](/docs/agent/buildkite-hosted/macos#macos-tahoe-26-dot-5) and [Tahoe (26.6)](#macos-tahoe-26-dot-6) include newer Xcode 26.x versions.
