I was able to boot and manipulate from another mac the capitan partition and obtain the ioregs and a new system.log file. I also attached my DSDT.
How should I do the rename? Could you provide some guidance or advise if there's a thread/post where this is explained in detail?
Sorry, I forget to ask also about how to deal with USB 3.0. Since the Mobo does no have built-in USB 3.0, I added a PCIe expansion card which is Renesas based. In Yosemite the generic kext you made enable the card, but how the card can be recognized in Capitan?
