Network issues can sometimes masquerade as device connection problems. A network diagnostic report can help you determine if the issue lies in your network configuration.To create a network diagnostic report:* Open the Network Utility app (Applications > Utilities).

Select the “Network Information” tab.
Choose your active network interface (e.g., Wi-Fi or Ethernet).
Note down your IP address, subnet mask, router address, and DNS server addresses. These are crucial pieces of information for diagnosing network problems.
Use the “Ping” tab to test your connection to your router and a public DNS server (like Google’s 8.8.8.8). Ping involves sending a small packet of data to a specific address and measuring the response time. High response times or packet loss can indicate network congestion or other issues.
If you suspect DNS problems, use the “Lookup” tab to test domain name resolution. Enter a website address (e.g., google.com) and see if it resolves to an IP address.

The network diagnostic report provides valuable data. If the ping tests to your router are successful but tests to a public DNS server fail, the problem is likely with your internet service provider or your DNS settings. If the “Lookup” test fails, it suggests a DNS issue. These are all things that could affect the file transfer process, especially if the Android File Transfer app relies on network services for communication.

The image displays the Network Utility application interface. The interface is divided into multiple tabs: “Info,” “Ping,” “Lookup,” “Traceroute,” “Whois,” and “Port Scan.” The “Info” tab is selected, displaying detailed information about the active network connection, including the IP address, subnet mask, router address, and DNS server addresses. The “Ping” tab allows for testing the network connection by sending packets to a specific address.

The “Lookup” tab allows for testing domain name resolution.

Testing the Connection Using the Terminal

The Terminal app (Applications > Utilities) offers a command-line interface, providing a direct way to interact with your Mac’s operating system. It’s a powerful tool for troubleshooting.To test the connection using the Terminal:* Open the Terminal app.

Type the command

`diskutil list`

and press Enter. This command lists all connected disks and partitions, including external devices.
Look for your Android device in the list. It may appear as a disk or volume with a generic name or the device’s model name. If you can see your device listed, it indicates that the Mac recognizes the hardware.
If your device is not listed, the problem might be with the device itself, the USB cable, or the USB port on your Mac.

The output of the `diskutil list` command will display information about connected storage devices. This information includes the device identifier, the disk type, the size of the storage, and the partition information. If your Android device is listed, this means that the Mac is, at a fundamental level, recognizing the device. If the device does not appear, there is a lower-level issue preventing the Mac from interacting with the device.

The image shows a Terminal window displaying the output of the `diskutil list` command. The output is a list of connected disks and partitions, each with a unique identifier, disk type, size, and partition information. The list includes the internal hard drive, any connected USB drives, and potentially the Android device.
