This post is from the WWDC26 App Attest & DeviceCheck Q&A.

Hi! I have not seen this year's video yet, so please forgive me if this is answered. I notice a couple of folks here saying that AppAttest is (at least partially) supported on macOS 27. Is this correct?

My specific use case is a "designed for iPad" app running on macOS. We use App Attest to make high-value requests to our headend services and would really like this to work on macOS as well.

Yes, starting in this year's OS releases, App Attest will work the same across all Apple platforms, including macOS 27. Your iPad app running on macOS 27 should work as it does for iPads on iOS 27.
