Windows users who want to access and control their Macs can set up a connection using the free Splashtop Remote app.
Accessing a Mac from a PC has always been doable by setting up VNC (virtual network computing) sharing on the Mac and installing a VNC client on the PC. But many people may find it quicker and simpler using Splashtop to create the connection.
Setting up access requires installing the Splashtop Remote app on your Windows PC and the Splashtop Streamer app on your Mac. Both are free and easy to install.
