Why can't I connect my iMac (Retina 4K, 21.5-inch, 2019) to my MacBooK pRO (13 inch 2020, Two Thunderbolt 3 ports) so that I can use the bigger screen of the imac but the better processing power of the Pro?

iMac 21.5″, macOS 10.15

Hi,

Your iMac isn't supported as Target Display Mode.

Use your iMac as a display with target display mode - Apple Support
