Galaxy S2 USB port blown, need to transfer files via wifi
Total commander with the LAN plug-in will let you copy the files to a regular shared drive, or you can use the wifi tool to setup a temporary custom share with another phone/tablet - it creates a share then displays a QR code which the other device then scans. Fast, free and easy. You will need to zip it first and create a shared drive on the MAC (which doesn't need any software but you can install it if you want).
