[HOW TO] OpenCore 0.6.5 > 0.6.6 differences

I replaced HfsPlus.efi with OpenHfsPlus.efi in EFI/OC/Drivers and that did the trick.. I'm on OC 0.6.6
Yes, I also switched to OpenHfsPlus but I didn't think that change could have resolved black screen.

I had the opposite- originally I had used the new "OpenHfsPlus.efi" when I made all the update changes from 0.6.5 -> 0.6.6. I had the blank screen problem and tried several things to rectify. The change that worked for me was to go back to using the original "HfsPlus.efi" (there was a comment about this on the IM discussion page).

Now 0.6.6 seems to work fine so I changed over on my main drive (I use a USB thumb drive EFI to test new versions). YMMV.

It is not clear how changing one driver for another can affect the black screen. It can be one of those seemingly inexplicable things we sometimes see in hackintosh. But what matters is the user experience. If you see that changing it fixes the bug, the change is well done.

The issue seems to be that some USB drives won't mount during the booting if it is used, so OpenCore does not get to the picker screen. I don't think it is a graphics issue, as I tried disabling OpenCanopy to get back to the text picker but that didn't work either.
The main point seems to be that the OpenHfsPlus.efi is not fully tested, which is why the current Dortania Guide does not yet recommend it as a default driver:

Yes, it may be as you say, OpenHfs is quite recent and maybe not mature yet.
But @67BGTEV says otherwise, he switched to OpenHFS and the problem was fixed.
 
After upgrading to 0.6.6 from 0.6.5 system is halting at the boot with the following error:

OCABC: Incompatible OpenRuntime r.11, require r12
Halting on critical error

I can't find anything regarding this error. Do you have any idea what does it mean ?

The explanation seems very clear, OpenRuntime driver must be r12 and not r11. Drivers and tools must be same version as OpenCore. Have you get drivers of 0.6.6 or have you left any of the previous 0.6.5?

Thank you @miliuco for this hint. Problem was caused by "old" HfsPlus.efi driver located in Drivers folder together with OpenHfsPlus.efi. I replaced it by OpenHfsPlus.efi and system is booting correctly now.

EDIT - new workng HfsPlus.efi driver for OC 0.6.6 can be also downloaded from this location : https://github.com/acidanthera/OcBinaryData/blob/master/Drivers/HfsPlus.efi
