macOS Packer Templates for Tart

Repository with Packer templates to build macOS Tart virtual machines to use with Cirrus Runners, Cirrus CI or any other automation.

The following image variants are currently available:

• macos-{sequoia,sonoma}-base image has only brew pre-installed and the latest version of macOS available
• macos-{sequoia,sonoma}-xcode:N image is based on macos-{sequoia,sonoma}-base image and has Xcode N with Flutter pre-installed
• macos-runner:{sequoia,sonoma} image is a variant of xcode:N with several versions of Xcode pre-installed and xcodes tool to switch between them.

See a full list of VMs available here.

Release Cadence

Once a new version of Xcode is released, we will initiate a GitHub release which will automatically build and push a new version of the macos-sequoia-xcode:N. This generally happens within 24 hours of a release. Please watch this repository releases to get notified about new images.

For an Xcode release which is non beta and not an RC ghcr.io/cirruslabs/macos-runner:sequoia image will also be updated.

Update Cadence

Some of the images are regularly getting rebuild in order to update the pre-installed packages. The following images are updated monthly on the first Saturday of the month:

• ghcr.io/cirruslabs/macos-{sequoia,sonoma}-base
• ghcr.io/cirruslabs/macos-runner:sonoma which is a superset of ghcr.io/cirruslabs/macos-sonoma-xcode:{latest,16,15.4,15.3,15.2}
• ghcr.io/cirruslabs/macos-runner:sequoia which is a superset of ghcr.io/cirruslabs/macos-sequoia-xcode:{latest,16.1,16.2-beta-1,16,15.4}

Note that ghcr.io/cirruslabs/macos-runner:{sequoia,sonoma} are updated every Sunday and these images are optimised for startup on Cirrus Runners and Cirrus CI services.
