Hello I managed to install Monterey on a macbook pro 17 "from 2009, but I think I have no graphic acceleration, I deduce it from the fact that when the mouse arrow scrolls on the menus you see shadows and staggered colors, I ask for a solution to the problem because this could depend on the VIRTUAL DJ application not starting that I mainly use, this problem has plagued me since the Catalina patch, the program is installed regularly, when I start I do not have its main screen but only the program menu that I do not does it does practically nothing, the mac has two video cards Nvidia 9400M / 9400M Gt. I ask you to help me solve this problem Thanks
You can get a discussion and catch up on the state of the art at macrumors.com, "Monterey on Unsupported Macs" thread.
But the response you got here is basically the answer: The 2009 is too old even for patched support in Monterey. A a previous macOS can still work while bridging the gap to a modern browser, etc.
What you are running into is that old HW doesn't have enough power to do transcoding at a baseline graphics generation, so they fall by the wayside.
In 2009 Intel was finally transitioned to fully 64bit with Core2, while for G-series GPU 1080HD decode was considered cutting edge.
PCs could play BluRay which is designed to for lighter weight decode while web video was typically SD. 30Hz QHD displays were top of line requiring exotica like DVI dual-link.
So there's a uncrossable graphics compute gap between that era and todays's 4K, inc full 4K transcode. And we're at point that latesr macOS dropped all hope of backwards compat because it is useless.
When the phone has dedicated HW that handles 4K 60Hz + in real time what good is the content it captures on a Mac that's struggling to handle 720 30Hz? No good at all.
To give you a sense of the progress...
A 2009 Macbook Pro Geekbenches at single / multi:
300 / 550
A 2021 iPhone at:
1600 / 4500
That's 5x to 10x bound in the core compute capability for a phone over a laptop.
Well, graphics power has evolved as much or more because the GPU + media engines are highly specialized to tasks.
So there you have it.
