Apple now accepting App Store submissions built for iOS 27, macOS 27, more

Apple has opened App Store submissions for apps built with the new iOS 27, macOS 27, and related SDKs ahead of next week’s OS launches, signaling an immediate upgrade cycle for organizations that develop or distribute Apple apps. The most strategic implication for IT teams is that macOS 27 drops Intel and Rosetta support entirely, which will force Apple silicon-only packaging, testing, and deployment decisions, while new age-rating, store asset, and metadata requirements add compliance and release-management overhead. CIOs and technology leaders should treat this as a near-term application modernization milestone and a preview of stricter platform enforcement coming in April 2027, when App Store submissions must meet the new SDK minimums.
