GPU update iMac 2011 for Mojave
Hi, I want to update my iMac 27" mid-2011 (iMac12,2 - i5) to Mojave.
I found the Mojave patch on iFixit but it's written that it doesn't work if you have a video card AMD Radeon HD 6xxx.
I have a AMD Radeon HD 6770M so I guest that it's not possible.
My question :
Is it possible to replace the video card in order to install Mojave (patch) ?
Which video card can I install ?
Thank you very much for your help
Is dit een goede vraag?
