Use it with a wifi router.
This modem is not a Wi-Fi combo unit like many DSL modem/routers. but it does accept my DIR-655 wireless router very nicely. My son's MacBook Air connects like a breeze.
Yes, this modem does support Apple Mac products. You can connect this modem to a Mac using the same equipment as a Windows PC.
Not sure if I understand your question, but if you have a wifi router to connect it to, you will get your TV programs and internet wirelessly on your tablets, iPads, etc. You can also connect it to "smart TV," but in and of itself, it is not wireless.
