Change Graphic Card

If you want the features offered by Mojave, you will need a more recent Mac to run that software. Your Mac is already nine years old -- a very long time in the fast-changing world of computers.

Planned Obsolescence has nothing to do with this, we are talking about ACTUAL obsolescence.

It cannot be done. The graphic card is not a swappable part.

Hello,

How can I change graphic card of my MacBook Pro Mid 2010 for upgrade to MacOS Mojave?

Not gonna happen, soldered into the CPU.
