Why I can't see 4K contents on my Mac mini 2020?

Have you paid Netflix for 4K service

which is only available with their "premium"

package?

Hey Valillo,

If we understand correctly, you are trying to watch Netflix on Safari and it is not in 4K. It may be that Netflix in Ultra HD requires the Apple T2 Security chip.

How to use Netflix on your Mac computer

"These Mac computers have the Apple T2 Security Chip:

• iMac (Retina 5K, 27-inch, 2020)
• iMac Pro
• Mac Pro (2019)
• Mac Pro (Rack, 2019)
• Mac mini (2018)"

"You can also use System Information to learn whether your Mac has this chip:

1. Press and hold the Option key while choosing Apple menu  > System Information.
2. In the sidebar, select either Controller or iBridge, depending on the version of macOS in use.
3. If you see "Apple T2 chip" on the right, your Mac has the Apple T2 Security Chip."
