How to increase the vRAM of the HD3000 macOS Sierra 10.12.2? Is there possible use the clover path
 
Go to folder /System/Library/Extensions and look for AppleIntelHD3000Graphics.kext and copy it to Desktop and somewhere else (in case something goes wrong).

open terminal and type this:
cd ~/Desktop/AppleIntelHD3000Graphics.kext/C*/M*

then use one of the following commands based on your actual vRAM

From 256MB to 384MB
sudo perl -pi -e 's|\xC7\x45\xBC\x00\x00\x00\x12|\xc7\x45\xBC\x00\x00\x00\x20|g' AppleIntelHD3000Graphics

From 256MB to 512MB
sudo perl -pi -e 's|\xC7\x45\xBC\x00\x00\x00\x12|\xc7\x45\xBC\x00\x00\x00\x20|g' AppleIntelHD3000Graphics

From 384MB to 1GB
sudo perl -pi -e 's|\xC7\x45\xBC\x00\x00\x00\x18|\xc7\x45\xBC\x00\x00\x00\x40|g' AppleIntelHD3000Graphics

From 384MB to 512MB
sudo perl -pi -e 's|\xC7\x45\xBC\x00\x00\x00\x18|\xc7\x45\xBC\x00\x00\x00\x20|g' AppleIntelHD3000Graphics

From 512MB to 1GB
sudo perl -pi -e 's|\xC7\x45\xBC\x00\x00\x00\x20|\xc7\x45\xBC\x00\x00\x00\x40|g' AppleIntelHD3000Graphics

And after that use Kext Utility (or any kext tool) to install your patched AppleIntelHD3000Graphics.kext , and reboot.

If something goes wrong use your USB flashdrive to boot again and replace it with your backup

PS: I used something like this for HD4000 to boost it up to 2GB of vRAM but there's no actual difference.

Why do you want to do that? It works with the defaults just fine...
