Boot Mac OS X Lion 10.7.5 and/or Mavericks 10.9.5 using Sapphire Radeon RX 570

[uaudio]

Hi everybody,

Can anybody suggest me a way how to inject a graphic card Radeon Pulse RX 570 8Gb to boot on Lion (10.7.5) and/or Mavericks 10.9.5? I just changed my Radeon HD5850 to RX 570 due to Metal 2 requirements in macOS Mojave. But the ability to use Lion 10.7.5 still important for me.
Thank you in advance!

My specs:
Core i5 3570k
Gigabyte z77X- UD5H
RAM 16 Gb DDR 3
Sapphire Pulse Radeon RX 570 8 Gb
UEFI boot Mojave/Windows 10 (separate SSD’s)

Not possible - The graphics card is too new to be supported in Lion.

Thanks for your reply. Then another question. I have an option to inject CPU integrated HD 4000. Can I boot Lion/Mavericks using HD 4000 without need to remove my RX 570 from MoBo? To be able just to connect a cable to MoBo VGA/DVI
