Vinnicius Posted August 5, 2012 Share Posted August 5, 2012 I'm trying to install the Mountain Lion on my notebook Acer Aspire 5750 / 5750G. The installer just boots when the kexts AppleIntelHD* and AppleIntelSNB* (or something) are deleted from S/L/E, and boot to installer with -x -v PciRoot=1 GraphicsEnabler=No After install boots only with PciRoot=1.

Vinnicius Posted August 5, 2012 Author Share Posted August 5, 2012 One more thing: I updated the BIOS to version 1.20. I don't know if this will help.
