I'm in trouble... The Cube has the new XCPM or not? I don't know why your DSDT give me KP at start (with clover and chimera boot loader), with my DSDT I don't have problem... Today I'll try again with a new clover installation with your new config.plist file. Stay tuned... EDIT: I've just installed Yosemite with clover method. With USB Drive used for installation, the system boot correctly (I changed only E1000 ethernet kext that doesn't work) with Clover installed in EFI partition of Macintosh HD, the system hang at boot (Error allocating 0x1401 pages...... Error loading kernel cache.....) What drivers I've to put in driver64 and driver64UEFI for normal boot? I've tried various combination, copying from USB stick but without success.
