Why Android File Transfer Stops Working
Android File Transfer (AFT) relies on the MTP (Media Transfer Protocol) over USB. It breaks frequently because:
- Mac updates — Ventura and Sonoma changed USB handling and broke AFT for many users
- Android 14 changes — newer Android versions changed how MTP is exposed
- USB cable issues — data cables look identical to charging-only cables
- Wrong USB mode — Android defaults to charging mode, not file transfer mode
- App not updated — Android File Transfer hasn't been updated by Google since 2021
5 Fixes to Try First
Fix 1 — Change USB mode on your Android
Pull down the notification shade on your Android. Look for "USB preferences" or "Charging this device via USB". Tap it and change to File Transfer (MTP).
Fix 2 — Try a different USB cable
Most USB-C cables are charge-only and won't work for data. Try the original cable that came with your phone, or buy a USB-C data cable specifically.
Fix 3 — Quit and reopen Android File Transfer
Force quit Android File Transfer (Cmd+Q or Activity Monitor), unplug the phone, then replug. Open AFT before unlocking the phone.
Fix 4 — Trust the computer on your phone
When you connect, your Android phone may ask "Allow access to phone data?" or "Trust this computer?" — tap Allow. If you already tapped Deny, revoke USB debugging in Developer Options and retry.
Fix 5 — Reinstall Android File Transfer
Download the latest version from android.com/filetransfer, then install it fresh. Sometimes the old installation is corrupted.
If none of the fixes work — or if you're tired of fighting with USB cables — there's a better way. Seyfr transfers files wirelessly, with no USB cable and no drivers.
The Better Fix: Transfer Files Wirelessly with Seyfr
SEYFR is free to use today and transfers selected files from supported Android devices to Mac or Windows over peer-to-peer networking. Install SEYFR on both devices; transfer time depends on the devices, network, and connection path.
- Open the Seyfr app on your Android phone and select Send
- Select what you want to send (Photos, Videos, Files, Documents, or a full Folder) to generate a QR code and token
- Open the Seyfr app on your Mac and select the Receive menu
- Paste the token, optionally choose a destination folder, and click Receive

Android File Transfer Not Working on Mac Ventura or Sonoma?
Ventura and Sonoma made significant changes to how USB devices are handled on Mac. Android File Transfer relies on a kernel extension (kext) approach that Apple has been deprecating since Big Sur. Many users on Ventura and Sonoma find that Android File Transfer simply never opens, or shows "Could not connect to device" even with a working cable.
SEYFR does not depend on USB or MTP. Compatibility still depends on the Mac, operating-system version, and current App Store requirements.
Other Android File Transfer Alternatives for Mac
Besides Seyfr, here are other options people use:
- MacDroid — works well but costs $19.99/year. Seyfr is free.
- OpenMTP — free, but still uses USB/MTP (same root problem)
- AirDroid — wireless but requires an account and limits transfer sizes on free tier
- Bluetooth — no USB but extremely slow for large files
- Google Drive/iCloud — requires internet, storage limits apply
SEYFR is a wireless, no-account option whose core transfer features are free today. It has no fixed application transfer-size cap, but device and network limits still apply.
Stop fighting with USB cables.
SEYFR transfers files from supported Android devices to supported Mac or Windows computers. Its core transfer features are free today.

Does Android File Transfer work on Android 14?
Android 14 changed the way MTP is handled and broke compatibility with Android File Transfer on many Mac systems. Google has not released an update to address this. Seyfr is not affected because it doesn't use MTP or USB.
Why does Android File Transfer say "Could not connect to device"?
This error usually means one of: wrong USB mode (set to charging instead of file transfer), a charge-only USB cable, or an MTP driver conflict on Mac. a wireless option is to switch to wireless transfer with Seyfr.
Can I transfer files from Android to Mac wirelessly without any app?
You can use Google Drive or iCloud, but these require an upload step and storage limits may apply. SEYFR uses peer-to-peer networking instead. SEYFR connects your devices directly with end-to-end encryption. Your files move straight from device to device without uploading to cloud storage. The app has no fixed transfer-size cap; device storage and platform limits still apply.
Does Seyfr work if I don't have Wi-Fi?
A same-network transfer may work through a local hotspot, but do not treat offline operation as guaranteed. SEYFR connects your devices over any internet or local network connection.
