This is the most common issue in hackintosh , Graphics injectors are not working properly.you have to use either one Gpu for osx intel or nvidia.Check you bios for disable gpu option.if you option dont have then it can be disable from DSDT or SSDT.so dont worry

what to do :

1. You can remove all the gpu kext from  installer to make the installer to work.

2.use nv_disable for nvidia and use proper injection for HD520

*if you have DMVT issue rehubman kext

also you can use lilu.kext for most of the patches

Intel hd 520 is supported in osx.all you need to do is inject intel and use injection Ids
