Hi guys! I have very weird question.
I have seen an used Macbook 2012, 15.4", 8GB RAM, i7 2.6Ghz.
With stated specs it should have 1024 of integrated VRAM memory, but everywhere in settings and in "About this Mac" section it shows 512 mgb only.
I am aware that with this graphics processor reserves 512 MB, 768 MB, or 1 GB of RAM for video function by with 4 GB, 8 GB or 16 GB of RAM installed, respectively).
In other 2012 i7 models with 8GB of RAM I have always seen 1024MB of VRAM.
If that helps it has very old system here - i think that it is 10.7.3 one.

Any ideas or explanations?

Thanks!

The VRAM allocations went up in later versions of OS X.

So If there would be upgrade... It should jump up to 1024MB?
Do I get it right?

BTW
Why there's no model-year shown?

More VRAM will not help performance at all, so you shouldn't worry about this.

What it reports there and what it's actively using aren't always the same, it's supposed to change as the machine requires more VRAM vs system RAM.
