QuickDrop is a free file transfer application designed for sharing files between Android and MacOS devices. Users need an Android device, a MacOS device, and a shared wireless network to use the app. Installation involves downloading QuickDrop from the Google Play Store on both devices. To transfer files, users launch QuickDrop on both devices, select the MacOS device from the list on the Android device, choose a file to send, and accept the transfer on the MacOS device. For sending files from MacOS to Android, users must add QuickDrop to the MacOS Share menu, enable it, and then select it when sharing a file. The transferred files are saved in the Downloads folder on the receiving device.
