THINKPAD T440 MINIDISPLAY PORT PROBLEM SINCE 10.14.2

[Sascha_77]

Since 10.14.2 my T440 always freezes when I insert a MiniDisplay Port Adapter. The display is still lit but no content is displayed anymore. Even the external monitor / TV remains dark. If I pull the adapter out again, the picture on the display but also not back. VNC is not synonymous anymore. You have to turn off the computer then hard.

The whole problem does not exist with 10.14.1 yet. I searched for the Hex value of the Clover Kext patch and it is found a couple of times. But apparently he has since 10.14.2 no effect. Does anyone have. an idea where for the HD4400 something has changed?

 

System report is attached.

 

What I can say:

 

It is clearly on AppleIntelFramebufferAzul.kext. I took the kext from 10.14.1 and put into 10.14.2. MdP worked again. So something has to be changed on Kext2Patch. Just ask what and where.

Having same issue.

 

First time I installed my hack on the thinkpad today. t440P with a i5-4300U on mojave 10.14.2 and facing this mini DP also.

 

unfortunately I do not have this older kext to use.

 

perhaps if you send me both files I can run a comparison for you?

Hello,

 

I have the very same problem with t440p with i5 4300m running Mojave 10.14.6. When I plug a mini dP to HDMI adapter and hook a monitor, the screen goes black and computer reboots. 
 

I have Lilu kext combined with whatergreen kext. 
 

Did you eventualy found a solution to this issue ?
