memey Posted March 3, 2013 Author Share Posted March 3, 2013 try > UseKernelCache=no -x -v if it boots do all the repairs. I already tried all flags but it stop on USBMC unknown identifier then "still waiting for root devices". I still figure out what's the problem.

sid124 Posted August 11, 2013 Share Posted August 11, 2013 Hi ya, is your laptop 14-b003sa C1W55EA? If so I have the same laptop and in now working with ML 10.8.4, only item not working is wifi card which I have replaced for Atheros AR5b95 and brightness controls.

memey Posted September 30, 2013 Author Share Posted September 30, 2013 Finally managed to get it working except wifi which I replaced with Broadcom adapter. Right now I'm using EFI device-properties to make graphic acceleration work. If someone want to share their DSDT or configuration to make it more vanilla, please let me know.

I have problem with brightness control too, only get full brightness after wake up from sleep. Have you manage to solve it yet? Link to comment Share on other sites More sharing options...
