Okay. So, I just bought a MBP 2012 13 inch base model, with 4 gb ram and intel HD graphics. From the 4 GB RAM, Graphics take 512MB. Is this normal? Shouldn't it be 380 or something?
 
No the maximum vram a Intel 4000 can hold is 768mb regardless of the ram. :apple:

So why did u say no?;) btw intel hd 4000 can holg 1 gb under windows.

To op: if you add 4more gigs, hd4000 will take 768mb and that is maximum under os x
 
How is the 1280x800 screen resolution on the 13" cMBP? I'm really interested in buying one before Apple kills them off.
 
I found a way to choose how much of VRAM you want your HD4000 to use under ML:
53574d1366143126-unified-appleintelframebuffercapri-ivy-probooks-1gb.jpg

I also made a script if you want to try it:
Code:
sudo perl -pi -e 's|\x00.{1}\x10\x07\x00\x00\x10\x07|\x00\x[COLOR="Red"]??[/COLOR]\x10\x07\x00\x00\x10\x07|g' ~/Desktop/AppleIntelFramebufferCapri.kext/Contents/MacOS/AppleIntelFramebufferCapri
Change the red ?? with the red number bellow to set the desired amount of VRAM:
10 = 256MB of RAM
18 = 384MB of RAM
20 = 512MB of RAM
30 = 768MB of RAM
40 = 1024MB of RAM

1. copy AppleIntelFramebufferCapri.kext to the desktop and make a backup of it
2. run the script in the terminal (dont forget to fill in the ??)
3. install the kext, rebuild caches (i would suggest kext wizard)
4. restart pray and let me know how it went

Disclaimer: this was not yet tested on a real mac (just a few hacks), so if you want to be the first to try, here is all the info you need.

Has anyone else tried going this? I would do it but i am a bit scared that something bad will happen to the computer.

I too would be interested in what this results in. Better performance? Bad results? Would it improve casual RTS-ing?

Worst case I can think of is that the driver wont load or not load correctly... all you have to do is replace the patched kext with the one you backed up. But if you dont know how to do that then I would say do not do it.

If you are interested in this, read this thread.
