Hi dear RehabMan and everybody!!
Today user vit9696 released a new anti-freeze solution Safari for hd4400 hd4600. For this you need to download two kexts.
But that's not all good news he...
I also did not use this solution because AppleALC audio.
I don't like to solve problems Hackintosh after each update of the system.
VoodooHDA.kext I haven't updated since Mavericks and I like this stability.
in the near future, probably go back to Mavericks I have no problems with hd4600
