r!ppz Posted December 16, 2018 Share Posted December 16, 2018 (edited) I am on 10.13.6 (17G4015). I use a GTX 1080 as main graphic card but trying to use the iGPU for compute tasks like video (de)coding. I am using SMBIOS 18,3. WhatEverGreen and Lilu are loaded through clover. This is my configuration in clover configurator: Result (IGPU in IORegistryExplorer): Still the card does not work (not loaded by the driver). Relevant entries from bootlog (filtered by "IGPU"): (AppleGraphicsPowerManagement) [AGPM Controller] build gpuDict by GPU IGPU. (AppleIntelKBLGraphics) [IGPU] Graphics driver failed to load: could not register with Framebuffer driver! busy timeout[0], (60s): 'IGPU' (IONDRVSupport) IGPU: Not usable Full config.plist and bootlog and bdmesg attached. boot.log bdmesg.log config.plist Edited December 16, 2018 by r!ppz Link to comment https://www.insanelymac.com/forum/topic/336912-i9-9900k-igpu-not-working-headless-mode/ Share on other sites More sharing options...
