1. Introduction:

Transferring files from Android to Mac is a bit painful, especially when the file sizes are huge. While the Android File Transfer (AFT) app on mac serves its purpose for files under 4GB, its limitations become evident when dealing with larger files. To overcome this hurdle and ensure swift and reliable file transfers, Android Debug Bridge (ADB) emerges as a powerful tool. In this technical guide, we'll explore the process of leveraging ADB to download files from an Android device to a Mac seamlessly.

2. Establishing Connection:

Before initiating the file transfer process, it's imperative to establish a connection between the Android device and the Mac via ADB. Ensure that ADB is installed on your Mac by following the official documentation provided by Android Developers.
To download ADB, visit the official Android Developer website here and download the Android SDK Platform-Tools package suitable for your operating system (in this case, macOS).

Once downloaded, extract the contents of the package to a directory of your choice on your Mac. For ease of use, consider adding the directory containing ADB to your system's PATH environment variable.

Connect your Android device to the Mac using a USB cable. Once connected, enable USB debugging on your Android device by navigating to Settings > Developer Options, and toggle the USB debugging option.

To enable Developer Options on an Android device, follow these steps:

Open Settings: Unlock your Android device and open the "Settings" app. It's usually represented by a gear icon.

About Phone: Scroll down to find and select "About phone" or "About device." This option may vary slightly depending on your device manufacturer and Android version.

Build Number: In the "About phone" menu, locate the "Build number" entry. This is usually found at the bottom of the list.

Tap Build Number: Tap on "Build number" multiple times (typically seven times) in quick succession. You'll see a message indicating that you are now a developer or that Developer Options have been enabled.

Enter Developer Options: Once Developer Options are enabled, you can go back to the main Settings menu, and you'll find a new option called "Developer options" or "System" with "Developer options" listed inside. Tap on it to enter the Developer Options menu.

Enable USB Debugging: Within Developer Options, scroll down to find and enable "USB debugging." You may be prompted to confirm this action by tapping "OK" or "Allow."

Remember to disable USB debugging when not in use to ensure the security of your device.

Open Terminal on your Mac and navigate to the directory where ADB is installed. Execute the following command to verify that your device is successfully connected:

adb devices

For all the commands below try with adb command first, if not working try with ./adb command, if still not working try with sudo ./adb command.

Example
adb devicesor ./adb devices or sudo ./adb devices

If still not working then your adb installation maybe wrong or you are in the wrong path where adb is not present

If your device is detected, you're ready to proceed with the file transfer process.

3. Navigating Directory Using ADB Shell:

ADB provides a powerful shell interface that allows users to interact with the Android device's file system directly.

To navigate to the directory/to find the exact directory containing the desired file, execute the following command:

adb shell

This command grants access to the Android device's shell. Use standard Unix commands such as cd, ls, and pwd to navigate through directories and locate the target file.

4. Downloading Large Files Using ADB Pull:

Once the desired file is located within the Android device's directory structure, initiate the file transfer to the Mac using the adb pull command. Specify the absolute path of the file on the Android device and the destination directory on the Mac where the file will be saved. For example:

adb pull /sdcard/path/to/file /local/path/on/mac

Example
adb pull storage/emulated/0/Download/filename.zip ~/Documents/
or
adb pull /sdcard/Download/filename.zip ~/Documents/

Replace /sdcard/path/to/file with the actual path of the file on the Android device, and /local/path/on/mac with the desired destination directory on your Mac.

Conclusion:

In scenarios where file sizes exceed the limitations of conventional file transfer methods like Android File Transfer, leveraging Android Debug Bridge (ADB) proves to be a viable solution. By establishing a direct connection between the Android device and the Mac and utilising ADB commands such as adb shell and adb pull, users can efficiently transfer large files with ease.

You can also send files using "adb push" command.

ADB also works over Wi-Fi, you can try that if you don't have a USB cable to work with or you forgot your mac adapter, since it doesn't have a USB port :(

Embrace the power of ADB to streamline your file transfer workflow and enhance productivity in mobile development and debugging endeavours.
