With QuickDrop, you can easily send and receive photos, videos, text files, and more between your Android phone and your Mac. Received files will be stored in your Mac's Downloads folder, and are transmitted over WiFi - so no Cloud is involved in the process.
The Mac application of QuickDrop can be downloaded from the Mac App Store. To send files from your Android device to your Mac, just select "Share" or tap the share icon for a file you want to transfer on your Android device, and select "QuickDrop". Your Mac will be listed as an available device.
After that, you will see a notification on your Mac. Hover over the notification to accept or decline the file transfer. Please note that your Android device and your Mac need to be on the same network to transfer files.
