Evolution of macOS infrastructure for Cirrus CI¶
We've been running macOS instances for almost 5 years now. We evaluated all the existing solutions and even successfully operated two of them on Intel platform before creating our own virtualization toolset for Apple Silicon called Tart. We are switching managed-by-us macOS instances to exclusively running in Tart virtual machines starting January 1st 2023.
