-# macOS 11 (Big Sur) onboarding guide
-
-macOS 11 pools were opened to existing customers only, and we are working on making them ready for production use, rebalancing capacity, and analyzing possible load.
-
-Meanwhile, we'd like to start including customers to private preview on demand. 
-
-> Big Sur will automatically become available to existing Enterprise customers. New enterprises and customers on other plans, please go through the sign up process described below.
-
-## Sign up process
-
-If you need to build and test your project with macOS 11, please, fill out the [form](https://forms.office.com/r/Pn0a7NqBXg).
-
-We will review the incoming requests periodically and open macOS 11 pool for some amount of them. These are the aspects we consider when processing requests:
-- _Pool capacity_. New onboardings are only possible if current performance won't degrade for existing customers.
-- _Billing plan_. New Enterprise or Teams customers will be given a priority in joining macOS 11.
-- _Necessity of macOS 11_. We can currently afford to add only those projects that really depend on the latest macOS version and its features.
-
-## Usage
-
-macOS 11 image label was changed to `macos-11` to avoid confusion with the minor version. We always update images to the latest available OS version. Use the following code snippet to run your builds on macOS Big Sur:
-```
-jobs:
-  build:
-    runs-on: macos-11
-```
