How to transfer files from Mac to Android via USB.
Connect the phone with a data cable, select File Transfer or MTP on Android, then use a Mac MTP app to copy files and folders. This guide shows the full wired workflow and the fixes for common connection problems.

macOS does not normally show Android MTP storage as a Finder drive. To transfer files from a Mac to an Android phone over USB, use a data-capable cable, unlock the phone, choose File Transfer or MTP in Android's USB preferences, and open a compatible Mac transfer app.
SmoothDroid shows the Mac and Android device side by side. You can drag files or folders into the Android pane, copy them with a button, monitor progress, and keep the transfer local to the cable.
What you need
A Mac running macOS 12 Monterey or newer.
An Android phone, tablet, media player, or other device that exposes USB File Transfer/MTP.
A USB cable that carries data. Some cables are designed for charging only.
A Mac MTP utility such as SmoothDroid, because Finder does not directly browse most Android MTP devices.
Before starting: save work in other Android transfer or photo-import apps and quit them. Only one app can reliably control the phone's MTP connection at a time.
Transfer files from Mac to Android in six steps
Install and open SmoothDroid. Open the downloaded DMG, drag the app into Applications, and launch it.
Connect Android directly to the Mac. Use a known data cable. While troubleshooting, avoid docks and USB hubs.
Unlock the Android device. Keep the screen unlocked while establishing the connection.
Select File Transfer or MTP. Tap the Android USB notification, open USB preferences, and select File Transfer, MTP, or Android Auto. The exact wording varies by phone maker.
Choose the Android destination folder. Open internal storage or an SD card, then browse to a folder such as Download, Movies, Music, Pictures, or Documents.
Copy the files. Browse to the source on the Mac side and drag files or folders into the Android pane. You can also select items and use the copy action. Leave the cable connected until the transfer queue finishes.
Drag a file from the Mac pane into the open Android folder. SmoothDroid shows progress while the file moves over USB.
Where should files go on Android?
Android apps usually scan familiar shared-storage folders. Using the expected folder makes the transferred file easier to find:
DownloadGeneral files, archives, installers, and anything without a more specific destination.
DCIM or PicturesPhotos and images you want gallery apps to discover. Avoid changing the phone's existing camera folder structure unnecessarily.
MoviesVideos, exports, and large media files.
MusicAudio files for music players that scan shared storage.
DocumentsPDFs, office files, text documents, and project material.
Some app-specific folders are protected by newer Android versions. If a destination is not writable, use a normal shared folder and import the file from inside the Android app.
Transfer files from Android back to Mac
The same connection works in both directions. Open the Android folder, select the files or folders you need, choose a destination on the Mac, and drag or copy them into the Mac pane.
For camera media, look in DCIM, Pictures, and Movies. Browser downloads are usually under Download. Messaging and recording apps may use their own named folders.
The two-pane layout keeps both filesystems visible and shows the active file, speed, and progress.
USB, cloud, wireless, or Bluetooth?
The best transfer method depends on file size, privacy needs, and whether both devices are on the same network.
USB/MTPBest for large files, folders, offline use, and direct local transfer. Requires a data cable and a Mac MTP app.
Cloud storageConvenient across locations and devices, but requires an account, upload time, available storage, and an internet connection.
Local wireless toolsUseful for occasional transfers without a cable. Both devices generally need the same network or a direct wireless connection.
BluetoothBuilt in, but usually impractical for large videos or folders because transfer speeds are comparatively low.
USB is the clearest choice when the files are large, the internet is slow or unavailable, or you do not want to upload private files to a third party.
If the Android phone does not appear
Unlock the phone and reselect File Transfer/MTP from the USB notification.
Disconnect and reconnect the cable, then try another USB port.
Replace the cable with one known to support data.
Connect directly to the Mac instead of through a dock or hub.
Quit Android transfer tools, photo import utilities, Preview, and cloud-sync apps that may be trying to access the phone.
Restart the phone and Mac if the USB interface remains unavailable.
Not when you transfer with SmoothDroid over USB. File contents move locally between the Mac and Android device. SmoothDroid does not require a cloud account, a browser extension, or a companion Android app.
The website uses basic analytics and Stripe handles purchases, but those services are separate from the files you transfer in the Mac app. See the SmoothDroid privacy policy for the complete description.
