+# VM instances and images for Build Cloud for macOS 
+
+When you use the Build Cloud for macOS:
+
+- Each of your jobs runs in a newly provisioned VM, which is dedicated to the specific job. 
+- The VM is active only for the duration of the job and immediately deleted. 
+
+## VM types
+
+The virtual machine where your job runs has `sudo` access with no password.
+For the beta, there is only one available machine type, `gbc-macos-large`.
+
+| Instance type | vCPUS | Memory (GB) |
+| --------- | --- | ------- |
+|  `gbc-macos-large` | 4 | 10 |
+
+## VM images
+
+You can execute your build on one of the following images.
+You specify this image in your `.gitlab-ci.yml` file.
+
+Each image is running a specific version of macOS and Xcode.
+

+# Build Cloud runners for macOS (beta)
+
+Build Cloud for macOS Beta provides on-demand GitLab Runners integrated with GitLab SaaS [CI/CD](../../../ci/index.md)
+to build, test, and deploy apps for the Apple ecosystem (macOS, iOS, tvOS). You can take advantage
+of all the capabilities of the GitLab single DevOps platform and not have to manage or operate a
+build environment.
+
+Build Cloud runners for macOS are in [beta](https://about.gitlab.com/handbook/product/gitlab-the-product/#beta)
+and shouldn't be relied upon for mission-critical production jobs. 
+
+## Quickstart
+
+To start using Build Cloud for macOS beta, you must submit an access request issue. After your
+access has been granted and your build environment configured, you must configure your
+`.gitlab-ci.yml` pipeline file:
+
+1. Add a `.gitlab-ci.yml` file to your project repository.
+1. Commit a change to your repository.
+
+The runners automatically run your build.
+
+## Example `.gitlab-ci.yml` file
+
+The following sample `.gitlab-ci.yml` file shows how to start using the runners for macOS:
+
+```yaml
+.macos_buildcloud_runners:
+  tags:
+    - shared-macos-amd64
+  image: macos-11-xcode-12
+
+stages:
+  - build
+  - test
+
+before_script:
+ - echo "started by ${GITLAB_USER_NAME}"
+
+build:
+  extends:
+    - .macos_buildcloud_runners
+  stage: build
+  script:
+    - echo "running scripts in the build job"
+
+test:
+  extends:
+    - .macos_buildcloud_runners
+  stage: test
+  script:
+    - echo "running scripts in the test job"
+```
+
+NOTE:
+During the beta period, the architecture of this solution will change. Rather than the jobs running on a specific VM instance, they will run on an ephemeral VM instance that is created by an autoscaling instance, known as the Runner Manager. We will notify all beta participants of any downtime required to do this work.
