Thanks for getting back to us with those additional details.

Hi heidilinde,

Thank you for posting in the Apple Support Communities. I understand that you want to buy TV shows in standard definition (SD) from the Apple TV app on your Mac, and I’d love to assist you.

By default, Apple TV will provide you with the best available quality resolution. To change this setting, open the Apple TV app on your Mac > Preferences > Playback > Download Quality > Up to SD. 

Keep in mind that if you purchase or rent an SD video, you can’t play higher-quality versions. Learn more here: 

Find and watch movies with 4K, HDR, Dolby Vision, or Dolby Atmos

From there, use these steps to buy TV shows:
