<< Solved >> Mojave 10.14.4 B360m pro4 + 9700K + RX480 - cannot load installer

After first reboot select install Mac OS , will restart 2 or 3 times.

It look like that after update performance is not so nice 7min compare to 6min20sec
If you check Picture, we have very unstable CPU usage and GPU, more CPU

Also intel IGPU is not in the list, maybe this is the reason for more load on CPU ...

still my second display doesn't work

Delete the dummy.kext , there no need for it after the update.
Try with SMBios iMac Pro 1,1

I did test with and without dummy kext
- with dummy kext - export process - 6min15sec - More CPU usage
- without dummy kext - export process - 6min39sec - less CPU usage

Do you know what should be change in order to add IGPU, after upgrade to 10.14.5?

 

[jackomito]

I changed back to the old configuration with EFI when I have 20min export process in order to test if Upgrade to 10.14.5 helping me to solve the issue
"with dummy kext - 6min16sec"
"without dummy kext - 6min20sec"

Also issue with display doesn't exist anymore
thanks!!!!!

Very good. Keep it Like that. You should delete dummy.kext, those features are enabled by default in 10.14.5.

Hi, again do you know how hard will to change configuration in order to keep only IGPU of intel in order to be able to remove in case of need RX480?

There is a problem, you're using i7 9700k and there is no mac with that processor, but we can spoof a fake IGPU ID.
It is easy to enable the IGPU output, let me know when you will do the switch.

hi, If this is too hard, don't worry about, i can keep external video, the ideal was to be able to keep more compact server case.
