Hex Fiend tool.

Kext Utility for refresh or install customized kext.

The SNB code is different again in High Sierra. In 10.13, the binary string to change is: C7 45 D0 00 00 00 xx Where xx is the byte to modify according to the default amount of VRAM (should be 18 or 20) and desired target allocation (say 20, 30, 40, 60, 80).

So, for instance, to change default VRAM on my E6220 (with 4GB RAM) from 384MB to 1024MB, the patch is: Find: C7 45 D0 00 00 00 18 Replace by: C7 45 D0 00 00 00 40

(Thanks to user Grama for the following tutorial!) When done with everything above, edit the Info.plist at AppleIntelHD3000Graphics.kext/C* Have to add after VRAMOverrride the VRAMSize key, it will be like this: <key>VRAMOverride</key> <integer>0</integer> <key>VRAMSize</key> <integer>1024</integer>

Add these last two lines (VRAMSize integer value should match with the value you picked to edit the first kext, save it and patch and fix the extensions with Kext Utility and you are good to go!
