Results are in: What's the oldest macOS you need to support?

Last week we asked you - here and on our social channels - “What’s the oldest version of macOS you support?”

After a week of replies, Big Sur was the most common cutoff point for macOS support.

Do you agree with the majority? How do you decide when to drop support for older OSs?


I actually have one job that targets 10.9 (Mavericks)! But it’s about to be phased out as it is transitioned from an Intel CI runner to Apple Silicon.

Usually I raise the target platform when upstream dependencies require it. Also I would not support any OS version that I cannot test on real hardware myself.


That is wild. The transition to Apple Silicon will be great I am sure though. And smart not to support anything you cannot test on yourself!
