I am creating a MacOS app embedding the QuickLook extension in it. The other day, I uploaded it to App Store Connect and had it reviewed. But it was rejected due to the following reason. Your app incorrectly implements sandboxing, or it contains one or more entitlements with invalid values. Please review the included entitlements and sandboxing documentation and resolve this issue before resubmitting a new binary. com.apple.security.temporary-exception.files.absolute-path.read-only / This entitlement is also included in my app's meta data on my account page of App Sore Connect. Including it, I can find the following two entitlements related to "temporary-exception" in the meta data. com.apple.security.temporary-exception.files.absolute-path.read-only: ( "/" ) com.apple.security.temporary-exception.mach-lookup.global-name: ( "com.apple.testmanagerd", "com.apple.dt.testmanagerd.runner", "com.apple.coresymbolicationd" ) To tell the truth, about Sandbox entitlements for QuickLook extension, what I intentionally set on the Xcode project are the next two items only. And actually I have not ever recognized that the entitlements related to "temporary-exception" above are included in my app's bundle. com.apple.security.app-sandbox: true com.apple.security.files.user-selected.read-only: true I think these "temporary-expection" entitlements are essential ones for the QuickLook extension and it looks like that Xcode automatically attached them in the process of creating app's build. If they are forced to be attached by getting the QuickLook extension sandboxed, I don't know what I should do. Although I explained my thought to the reviewer, but I could not change the situation. Is there no way to get solution besides removing the QuickLook extension from my app ?
