Catalina 10.15.1 clover 2.5k_r5098 Netflix in safari, DRM problems and sidecar

hi everyone,

since the Hackintosh built in my pc, the problems always existed.

here's my build:

MB: gigabyte B75m D3h

CPU: i5 3470

RAM: DDR3 1600 12GB

SSD: Micron sata3 500GB

graphic card: gigabyte RX 570 4GB

monitor: 1920x1080@60

everything went flawlessly except Netflix in safari, apple tv+, and sidecar

when in iMacPro1,1, whether enable/disable igpu, the above three won't work

when in iMac19,1, enable igpu, only sidecar will work, but it gets choppy on my iPad mini5（w/latest OS). whether in wifi or connected USB 3.0.

have been searching for the solution but in vain, i get the only way to make sidecar work is to change smbios to imac19,1.

but can anyone teach me how to solve the netflix in safari problem, and DRM things?

thank you guys
