Hi RehabMan,
As I don't know how to solve my problems before, I reinsatalled OS X10.11.4 on my computer by using the plist of
config_HD5300_5500_5600_6000.plist from you, the whole process of insatallation goes well until I enter in the system. I encountered the same same problem, it could not boot.
I found that when I inject platform ID (0x1626006), it can't boot.
when I try with 0x1626003 and 0x1612006, it can boot, but there are only 7M graphic memory, I don't know why? and I also tried to set my pre-alloc to 64M, 96M and 128M, it seems that my modification of pre-alloc value have no effect to boot.
Please help me, I got stuck here for several week, the problem is that I don't know where is the problem, if we can find it, it would be easier to fix it.
