We have an app with the default email entitlement that was granted several years ago. During our latest deployment, we received an error from our pipeline. When testing a manual submission in Xcode, we saw this error: Entitlement com.apple.developer.mail-client not found and could not be included in profile. This likely is not a valid entitlement and should be removed from your entitlements file. We checked the provisioning profile, and the default email entitlement is still present. It is visible on the certificate portal and also in the embedded.mobileprovision file. Can you suggest what we can do to release a new version of our app?

Hi, I’m hoping someone can help clarify the correct entitlement format for the Enhanced Security capability in a macOS App Store build. Context Our app is a sandboxed macOS app built with Xcode 26.4. We enabled the Enhanced Security capability in Signing & Capabilities, and we configured the entitlements based on the current documentation. What’s confusing me The Xcode 26.4 release notes say apps that already adopted Enhanced Security should remove: com.apple.security.hardened-process.enhanced-security-version com.apple.security.hardened-process.platform-restrictions and replace them with: com.apple.security.hardened-process.enhanced-security-version-string with value 1 com.apple.security.hardened-process.platform-restrictions-string with value 2 Reference: https://aninterestingwebsite.com/documentation/xcode-release-notes/xcode-26_4-release-notes The entitlement reference pages also seem consistent with that: https://aninterestingwebsite.com/documentation/bundleresources/entitlements/com.apple.security.hardened-process.enhanced-security-version-string https://aninterestingwebsite.com/documentation/bundleresources/entitlements/com.apple.security.hardened-process.platform-restrictions-string So our app currently uses the new -string entitlements with values "1" and "2". Our App Review rejection said: The app incorrectly implements sandboxing, or it contains one or more entitlements with invalid values. Entitlement "com.apple.security.hardened-process.enhanced-security-version-string" value must be boolean and true. Entitlement "com.apple.security.hardened-process.platform-restrictions-string" value must be boolean and true. That’s the part I can’t reconcile with the documentation. Questions For a Mac App Store submission built with Xcode 26.4, should these two entitlements use the new string-based form, or Boolean true? If the expected format has changed, is there any updated guidance beyond the Xcode 26.4 release notes and current entitlement reference? If Apple staff or anyone familiar with this can clarify what format is currently expected, I’d really appreciate it. Thanks.
