· 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)

· System Manufacturer Apple
· Exact model number: Imac 24"

Probably caused by : [COLOR=#ff0000]MacHALDriver.sys[/COLOR] ( 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?

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.

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
