mrphumin Posted August 14, 2014 Share Posted August 14, 2014 I successfully install OS X Mavericks on my laptop(Acer V3-471G) by using USB created by #####. If i use that USB to boot in legacy BIOS it can recognize my HD4000(1024 VRAM) and has full qe/qi, but if i use another USB that has Clover bootloader(Newest Build) in it and boot in UEFI mode, it can recognize my HD4000 but has only 4 MB VRAM. How can i fix this?This is what i had done1) Patch IntelFrameBuffer kext using patch from insanelymac2) Add <key>VRAM</key><integer>1024</integer> in config.plist of clover and change to other value such as 2048, 4096, 5123) Inject HD4000 in clover with ig-platform-id=0x01660009 or 0x016600034) Boot with GraphicsEnabler=Yes GraphicsEnabler=No IGPEnabler=Yes IGPEnabler=No5) Config FAKEID for HD4000 as 0x01660009 or 0x01660003 Link to comment Share on other sites More sharing options...
mendietinha Posted August 14, 2014 Share Posted August 14, 2014 wrong from the very beginning. this tool is not supported by this forum, those flags are not for clover, but for chameleon. take a good read at the install guides. btw the flags for clover are like this: <key>Graphics</key> <dict> <key>Inject</key> <dict> <key>ATI</key> <false/> <key>Intel</key> <true/> <key>NVidia</key> <false/> </dict> <key>ig-platform-id</key> <string>0x01660003</string> </dict> Link to comment Share on other sites More sharing options...

Get your system working without patches to the framebuffer first (patching the framebuffer is only necessary for certain features/scenarios) 2) Why? 3) That's fine, but usually... 01660009 is used for higher resolution screens (1600x900 and larger), same for 01660004. 01660003 is used for 1366x768. Use the id that is appropriate for your screen resolution. 4) Not for Clover 5) No need for FakeID and both of those IDs are invalid vendor/device IDs. If your goal is to disable HD4000 drivers, that's a good way to accomplish it. Link to comment Share on other sites More sharing options...

But when i remove fake ID, restore original kexts , and use 0x01660003, i got 1024 VRAM and full qe/qi. I want to ask some another question. Can i enable Nvidia geforce GT 640m(Kepler) in Mavericks?(I deleted all NV*.kext) Link to comment Share on other sites More sharing options...
