Daw989 Posted January 15, 2017 Share Posted January 15, 2017 Hey Folks! Ive got a Lenovo Ideapad System, ive installed sierra 10.12 and it went great but id researched the HD 5500 Graphics and it requires you to change the DVMT Allocation, mine was pre allocated with 128MB of VRAM. I tried to Chage the DVMT using an EFI Shell and the command "setup_var 0x18C 0x3" Which would change the dvmt from 128MB to 96MB but the BIOS' are locked so i cant do that instead I checked for patching methods, I changed the Binaries of the AppleIntelBDWGraphicsFramebuffer Kext I replaced "8945C839C7764F" with "8945C839C7EB4F" and added the MatchOS for 10.12, after that I also set the platform ID to 0x16260002 and then rebooted. It Partially worked as in Verbose mode there were several lines about the IGPU saying it was registering Correctly and there was 3D Acceleration, so its working except it freezes/Hangs at these IGPU Lines and I cant see the login screen. Some others are saying they can see the Mouse and hear the keyboard typing (??????????) I don't see anything other than the Verbose Messages hanging at the IGPU Lines. Has anybody else had this issue and resolved it or any other methods other than Clover Kext Patching and Modifying the BIOS Physically or Via Software!? My Specs are: CPU: Intel Core i3 5005u GPU: Intel HD 5500 RAM: 8GB HDD: 500GB Hitachi Id be Super Super Grateful if anyone would help me out and try to fix this Issue without DVMT or BIOS Modding!

Moderators Jake Lo Posted January 16, 2017 Moderators Share Posted January 16, 2017 Change platform-ID to 0x16260006 Disable/Enable CSM to see if it makes a difference in the BIOS. Link to comment Share on other sites More sharing options...
