iMazing 3.6.3 Restores Sideloading of Removed iOS Apps via macOS After Apple Authentication Changes

Developers of iMazing have released version 3.6.3 that restores the ability for users to download and install applications previously removed from the App Store onto iPhone devices. The update currently functions only through macOS, with Windows support still pending further development. The changes address authentication and download errors that appeared in macOS 26 and earlier versions following modifications by Apple to its CommerceKit system. Apple began returning HTTP 403 Forbidden responses to tools including iMazing, ipa_downloader, and 3uTools by deactivating legacy tokens and revoking certificates used for app authentication. The restrictions have particularly affected Russian users who relied on these tools to reinstall banking and other applications removed due to sanctions. Support for macOS 27 Golden Gate and Windows remains unavailable and requires additional engineering work.
