So my friend has a tv but she doesn’t want to get cable since there’s Hulu, Netflix,etc but she doesn’t have any type of adapter/HDMI to connect her phone or computer. I want to buy her one as a housewarming gift but I am totally ignorant. She has an IPhone and a MacBook Air. The MacBook only has a USB port. So my question is: what do I buy that will connect both her Mac and phone to her tv?
