And theoretically putting in 160 to get 4gb of vram should have worked too. I'll test the 120 once I get a new hard drive to put time machine into.
Got a tip for us?

Hi,
Just wanted to know if this also worked on Intel HD3000, beauause the less RAM we have on a MPB the less V-RAM apple gives us. BUT from 8gb-16gb the ammount doesn't change... I'd like to get 1-2gb of V-RAM on my HD3000 with 16GB RAM...
Any code???

He is translating hexadecimal to decimal values. Basically, there are 16 values for hex: 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F. You can read hex in pairs of values. As long as the decimal value is < 10, you read it numerically. However, you match up values 10 - 15 with each letter thereafter, ie, 10 = A, 11 = B...16 = F.....etc.
So hex C0 translates to 12 0, and 9B is 9 11. From these values, you can translate to binary. Ie, 12 0 is 1100 0000, and 9 11 is 1001 1011. Hope that clears it up. Sent from my iPad.

Yeah I'm still clueless, sorry so exactly what would I have to do to obtain 3gb of vram? Like what value should I change from "sudo perl -pi -e 's|\x00.{1}\x10\x07\x00\x00\x10\x07|\x00\x??\x10\x07\x00\x00\x10\x07|g' ~/Desktop/AppleIntelFramebufferCapri.kext/Contents/MacOS/AppleIntelFramebufferCapri" to get the 3gb?
Idk if you are the author of the video, but he makes a crucial mistake... Saves the kext to Downloads and then uses the script without changing the target directory.
Code:
~/[B]Desktop[/B]/AppleIntelFramebufferCapri.kext/Contents/MacOS/AppleIntelFramebufferCapriI have no idea but you're probably right. I'm wondering if using this hack will actually allow for a better system, graphically speaking, or if it will cause harm to computer. Also, will it heat it up?
Valid in yosemite 10.10.1?
@gu1k:
I have heard that in the beta builds of yosemite this works. No word if it works in current builds. Can anyone try this out?

I can confirm that this hack works on macbook pro mid 2012 running yosemite 10.10.1... and it works really well... I have 2gb of ram allocated to my vram and it improved my frame rate in Counter Strike Source from around 30 to 60 fps!!! Incredible...
I copied the kext to desktop
Ran the terminal command to patch the kext
Installed with kext wizard
Repaired permissions from within kext wizard
"Intel HD Graphics 4000 2048 MB"
Rebooted and it worked... Im not sure if its just me... but it may have made the color on my display a little cooler/bluer... I don't know if this is actually true... anyways, this is freaking awesome!!!

sorry what is the point of this on Yosemite ? How does it improve the usage ? I'm on MacBook 2012 retina .
Hello,
I did exactly the same on "Mac mini (Late 2012)" and I get "Display 7 MB" at 10.10.1.
May anyone help me?

Thanks,
Yeah, I can cofirm that this hack dosen't work with mac mini. I've tried on 2 different ones (late 2012 and 2014), both have their ram maxed out and running Yosemite 10.10.2.
Scratch my above post. I've managed to get this hack working on a mac mini late 2012 (Yosemite 10.10.2).
After doing a clean install of the operating system the hack works with the instructions written by kpkp in the first post.
I will post below the screen shot.
For the record, I've tried upping the value of vram to 3gb, trying with C0 and 120, but didnt worked. No problem at booting, only displaying in system information :"display 7mb" and the computer was working very slowly (like I didnt had installed the graphics driver).
After installing diablo III and league of legends, I can say with great regret that upping the vram on this dosen't improve FPS or game play in any way.
Sad but true!
Thank you kpkp for trying.
Have a nice day.

I tried this with yosemite 10.10.3 and my hd 4000 went to 3MBs, now if im trying to hack it to 2048 will i have to have the 16GBs of ram installed?
Hi kpkp, today i bought a mbp 13 mid 2012 motherboard and i swap it for my older mpb late 2011 (16gb ram), and everything is working, i didnt format or reinstall OsX, i bought it only cos of the vram of this mbp mid 2012, with yosemite and mavericks the vram is 1gb, but on mountain lion is only 512mb, so i tried your tutorial and it didnt work, i follow your steps, back up the kext file, use the script in terminal replacing [??] (i used first 80 and then 40)
then install with kextwizard, rebuild cache and repair permissions also with kextwizard. but nothing no 2gb or 1gb, i dont think im doing something wrong. could it be the swap of motherboards (i dont think so)?
Thanks for your help and this script!!!

I have the same Model as you, but when I did all of this and rebooted, I lost all my VRAM - I only have Screen 3MB now and it's impossible to do anything. I had to use recovery to get it back to where it was. Can you help me?
Boot into safe mode and put the original Kext back to the Extension Folder.
If you didn't back up the Kext you can find it when you download the OS (X) version you have and use Pacifist to copy the Kext back to the Extension Folder.
It's easy enough to restore the kext files, I just want to find a way to make this hack work. Maybe I'm asking for two much VRAM (I have 8 system RAM) - if I do 60, will it do 1.5 GB rather than 2 GB as I have been trying until now?
