It’s a well-known fact that files sharing between Android and macOS devices have always been difficult, often necessitating the use of third-party apps or websites like Snapdrop. NearDrop, an open-source app created by developer Gregory K, also known as grishka, makes the process much easier by reverse engineering Google’s nearby share and enabling macOS to receive files from an Android phone.
However, NearDrop only functions as a receiver, so you can’t use it to send files from your Mac to your phone. Furthermore, file sharing is only possible when both devices are connected to the same network.
