Yes it works. My iMac 9,1 has HD 4850.Hey guys!
I’m trying to update Mac OS to Catalina on my mid 2010 iMac, but as I found out I can’t do it with Radeon HD 5670 I have.
So I wonder if I can replace a video card, and install HD4850 instead of current HD5670?
Would this GPU even work in my iMac? And does the patcher work with Radeon HD 4850?
