AnDrop is a simple tool that aims to imitate the ease of use a similar non-Android OS app provides.
A tap on the share button inside your photo gallery or file explorer starts the WiFi discovery and let's you share the file to any mac in the same WiFi without any setup. Just install and start the AnDrop client on your mac and you are good to go.
It is fast, easy and get's the job done. Let me know in the reviews what you think of AnDrop!
Disclaimer: Since I had multiple people thinking a tip is needed for this app to work: AnDrop is free and will stay free! So tipping is absolutely voluntary!
