iCloud Backup Tool Frequently Asked Questions

Apple requires an App-Specific Password for third-party mail apps instead of your normal Apple ID password. How to create one

1. Log into appleid.apple.com with your Apple ID.
2. Navigate to the 'Sign-In and Security' section.
3. Click 'App-Specific Passwords' and select 'Generate an app-specific password'.
4. Label it 'Prism iCloud Backup' and copy the 16-character password directly into Step 1 of the tool.

Yes. Prism natively supports all Apple email domains: @icloud.com, @me.com, @mac.com, as well as custom iCloud email domains configured under iCloud+. Simply click the appropriate domain chip in Step 1.

Yes. Select Outlook PST as your target format in Step 4. Prism streams messages directly into a clean, standalone Unicode PST file compatible with Outlook 2024, 2021, 2019, 2016, and Microsoft 365. You do not need Microsoft Outlook installed on your computer.

Yes. Prism generates native Apple Mail EMLX files complete with XML property list (.emlx) metadata headers. You can drag and drop these exported folders straight back into macOS Mail.app without losing message flags or threading.

Select PDF Document in Step 4. Prism converts each email into an ISO 19005-1 compliant PDF/A file, complete with sender headers, timestamps, customizable Bates numbering (e.g., CASE-00104), and original binary attachments embedded directly inside the document.

Connect your account in Step 1, select your target format in Step 4 (like PST, MBOX, or PDF), and run a complete local backup. Once your emails and attachments are verified on your local hard drive, you can safely delete older messages from iCloud to reclaim your free 5GB quota.

You won't lose progress. Prism includes an embedded SQLite ACID checkpoint database. If a session halts, reopen the application and click 'Resume'. The engine reads the checkpoint ledger and continues downloading from where it stopped without creating duplicates.

Yes. Prism is compiled as a Universal Binary supporting ARM64 (M1, M2, M3, M4) Apple Silicon Macs and Intel x86-64 chips natively. It runs without Rosetta 2 translation and is fully notarized for macOS Sonoma and Sequoia.

Easily. When selecting PST format in Step 4, check the Auto-Split option and pick a size threshold: 2GB, 5GB, 10GB, 20GB, or 50GB. The engine cleanly partitions your archive into sequential volumes without splitting email threads.
