· Age of OS installation - have you re-installed the OS? Upgraded to Windows 10 in August

· CPU Intel Core i5-2400S 2.5GHz
· Video Card
· MotherBoard - (if NOT a laptop)
· Power Supply - brand & wattage (if laptop, skip this one)

BugCheck 19, {20, ffffe0010f6b2350, ffffe0010f6b2410, c0c001d}

Probably caused by : MacHALDriver.sys ( MacHALDriver+1714 )

One of your MAC OS drivers appears to be causing problems, I highly doubt that it is compatible with Windows 10, and thus leading to the BSODs your experiencing. Is this a dual boot system, or have you installed Windows on a Apple Mac completely?

Code:

0: kd> lmvm MacHALDriver

start             end                 module name
fffff800`3f760000 fffff800`3f76a000   MacHALDriver T (no symbols)

The issue appears to be lie with how the operating system is handling pool allocations, the POOL_HEADER structure appears to be corrupt. This is possibly due to a incorrect release of memory.

Code:

0: kd> dt nt!_POOL_HEADER
   +0x000 PreviousSize     : Pos 0, 8 Bits
   +0x000 PoolIndex        : Pos 8, 8 Bits
   +0x002 BlockSize        : Pos 0, 8 Bits
   +0x002 PoolType         : Pos 8, 8 Bits
   +0x000 Ulong1           : Uint4B
   +0x004 PoolTag          : Uint4B
   +0x008 ProcessBilled    : Ptr64 _EPROCESS
   +0x008 AllocatorBackTraceIndex : Uint2B
   +0x00a PoolTagHash      : Uint2B

The call stack:

Code:

0: kd> knL
 # Child-SP          RetAddr           Call Site

Check this article to make sure that your system is compatible with W10 in BootCamp: https://support.apple.com/en-us/HT204990
The MacHALDriver dates from 2011, so I'd have to wonder if it's compatible w/Win10

I haven't been able to locate the driver download for BootCamp 6 - I suspect it's all automatically downloaded when installing W10 but will have to do more research to see
