Is there an app for my Mac (Mojave) that will allow me to stream AppleTV+ videos from my iPhone or iPad to the Mac?
Try AirServer or Reflector. Both come with a free trial. Then Airplay from ATV+ app on your phone/pad.
Thanks for this link. We finally tried it last night with Greyhound. Strangely, I could not get it to work with Safari (play button with a diagonal line through it) but it ran fine in Firefox. It looked like it should have had Dolby Digital, but my receiver did indicate it was receiving a DD signal. The video seemed to be DVD quality on our 1080p projector. Not all that impressed with Apple TV.I don't think there is, but I believe you should be able to watch them on https://tv.apple.com on your Mac with Mojave, since it doesn't have the TV app.
you're watching it in a web browser, and then air playing. Quite possibly the worst way to do it.Not all that impressed with Apple TV.
No, not using Air Play. I'm using Firefox on my Mac connected to an Onkyo receiver via HDMI, which is connected to my Epson 1080p projector. Netflix and Amazon video quality are definitely better.you're watching it in a web browser, and then air playing.
