Transfer by USB on Windows or Mac

Updated May 6, 2026 5 min read

USB is the right fallback when WiFi discovery is blocked, the home network is unreliable, or you do not want to troubleshoot router and firewall settings. It is also the most predictable choice on managed or corporate computers.

On Windows, the cable alone is not always enough. Your PC may need the correct Apple device drivers. On Mac, use a reliable cable and approve any trust prompt. In all cases, the iPhone must be unlocked and Simple Transfer must stay open on iOS.

USB setup checklist

Use a data-capable cable, not a charge-only cable.
Connect directly to the computer when possible. Avoid weak or unpowered hubs.
Unlock the iPhone before opening the Desktop app.
Tap Trust This Computer if iOS asks.
Keep Simple Transfer open and active on the iPhone during transfer.

Windows-specific checks

If Windows cannot see the iPhone over USB, Apple device drivers may be missing or broken. This is common after Windows updates, old iTunes installs, or driver conflicts with Apple Devices for Windows.

Quick test: see if the iPhone appears in File Explorer at all. If Windows itself cannot see it, fix the Apple driver path before troubleshooting Simple Transfer.

Mac-specific checks

Make sure the iPhone is unlocked when you connect.
Approve any Trust This Computer prompt on the iPhone.
Approve any macOS device prompt if shown.
Try another cable or USB-C port if the iPhone does not appear.

Speed expectations

Older Lightning iPhones can be limited to USB 2 speeds even on a modern computer. USB-C iPhones (iPhone 15 and newer) can be much faster. USB is not always dramatically faster than WiFi, but it is usually more stable.

For very large transfers, reliability matters more than peak speed. Use a destination drive with enough free space and stop the computer from sleeping mid-transfer.

If USB keeps disconnecting

Try a different cable.
Try a different USB port (avoid hubs).
Disable sleep on the computer until the transfer finishes.
Keep the iPhone charged.
Use smaller batches if one large batch keeps failing.
