I'm an IT supporter and a paying TeamViewer customer. My clients are Win and Mac users with their own private equipment. They phone in; I direct them to a link to our client download (get.teamviewer.com/6yh7whg), and hope they get an ID and password so I can help them. Unfortunately, what they need to do after clicking my link before they get an ID depends on their browser, OS, and security settings. With inexperienced users, getting through this may be more complicated than the problem they are actually calling about. (Sometimes, they don't even know if they have Win or Mac, and much less which version or which security settings they have.) Especially with newer Macs, the security settings they need to fix first are a serious problem. I need to see their screen, but preferably also to control their mouse. Hence my question: "IS THERE A SIMLPE VIDEO GUIDE OR MANUAL TO WHICH I CAN DIRECT INEXPERIENCE MAC USERS, THAT IS (NEARLY) GUARANTIED TO HELP THEM THROUGH THIS?"
