Regardless of the macOS version your Mac is running, open the App Store page of the latest macOS version – Monterey – and download the installer from there. Even if you have access to a Mac, you won’t be able to download a copy of the OS you already have installed. Getting hold of an ISO is actually more difficult than you might expect.

You’ll also need an ISO image of the macOS version you want to install.

You can execute your build on one of the following images. As time goes on, GitLab increments their versions synchronously (meaning we build macOS 11 with Xcode 12, macOS 12 with Xcode 13, and so on). GitLab then does only unavoidable changes: security updates, runner version upgrades, and setting the production password.īoth macOS and Xcode follow a yearly release cadence.

The image for the previous OS version ( 11) moves to frozen mode.

GitLab continues making Xcode updates, security updates, and any non-breaking changes deemed necessary. The tools GitLab builds into the image with Homebrew and asdf are frozen. Tooling often gets critical bug fixes after the first public release of an OS version. GitLab will try to minimize breaking changes between the first two minor versions but makes no guarantees. The long-term name will not include beta (for example, macos-12-xcode-13), so customers are moved automatically out of beta over time. The image is considered beta and the contents of the image (including tool versions) are subject to change until the first patch release ( 12.1). GitLab expects to release new images based on this cadence:įor new OS versions: When Apple releases a new macOS version to developers (like macOS 12), GitLab will plan to release an image based on the OS within the next 30 business days.

The expectation is that virtual machines running on the Apple M1 chip will be available in the second half of 2022.Īt this time there is only one available machine type offered, shared-macos-amd64. GitLab SaaS provides macOS build machines on Apple servers with Intel x86-64 processors. That process will likely increase the total job duration. Each time you run a job that requires tooling or dependencies not available in the base image, those items must be added to the newly provisioned build VM.
