ManIkWeet Posted October 28, 2013 Share Posted October 28, 2013 Hi After a short time of usage, I get horrible graphical glitches on my screen. See screenshots: I can temporarily remove the glitches by changing resolution to scaled and then back. I have a single resolution available: 1600x900 Graphics kexts are stock Apple. I am on OS X 10.9 (13A598). My bootloader is Clover, but I am willing to switch to Chameleon if needed. OS X recognizes same EDID as Windows, though said EDID does not seem complete. HDMI Connector does seem to work properly, though graphic glitches do appear on external monitor. I can not change VRAM in BIOS. On verbose boot, I get the infamous "Buffer pool allocate failed" message. Connectors: Internal LCD VGA HDMI Hardware specifications: Intel i5 2410m, 2.3GHz Intel HD3000 with device id = 0x01198086 4GB 1333MHz DDR3 RAM Intel Mobile HM65 chipset Laptop/Notebook model: Asus K73E-TY071V Link to comment Share on other sites More sharing options...
