Kernels for Pentium D for OSX 10.10 and 10.10.5
Sorry for the lack of information before:
Kernel6 - 10.10.5
yosemite3 - 10.10.0 - 10.10.3
I have tested this kernels and I am currently using them. One problem that I found with yosemite3 is screenshots don't work but just update to 10.10.5 and use the kernel6 kernel.
