When you download apps from the App Store, you may see an error:
iOSAppDownloadManager – request failed … 403
iMazing is currently unable to authenticate with Apple Accounts to download apps due to recent changes on Apple’s end. This issue affects macOS 27 Golden Gate and all Windows versions. However, we’ve restored functionality on macOS 26 and earlier.
We’re working to restore this feature as soon as possible.
In the meantime, if you have a Mac, you can use macOS 26 or earlier.
