{Not urgent} Not working on 10.12 Beta about mac-pixel-clock-patch-v2 HOT 17 OPEN

@Kazom please try this one with dp3 supported. Floris497 will update his github since he is busy these days.

I will look at it later today

from mac-pixel-clock-patch-v2.

Hm.. So it looks like the public beta is different from the dev beta. Can you try running patch.command patch v7 and see if that works? If so post the new md5 output :)

from mac-pixel-clock-patch-v2.

@Floris497 it does install on my MacBook with the latest beta (16A238m).

But the laptops freezes on connect to 4k display, but the display itself says that there is a 60hz 4k stream.

@giulioungaretti @Floris497 the pixel clock has moved to /System/Library/Frameworks/CoreDisplay.framework/Versions/Current/CoreDisplay in Sierra, same patch in different location:

gTarget_Framework_Repo="/System/Library/Frameworks/CoreDisplay.framework/Versions/Current/CoreDisplay"
sudo perl -i.bak -pe 's|\xB8\x01\x00\x00\x00\xF6\xC1\x01\x0F\x85|\x33\xC0\x90\x90\x90\x90\x90\x90\x90\xE9|sg' ${gTarget_Framework_Repo}
sudo codesign -f -s - ${gTarget_Framework_Repo}

Can be found here in my git.
Successfully tested on my Dell Precision M3800 with QHD+ ;)

Best wishes,

Great work! I will look at it at home :)

@Floris497 I've already pulled a request for you :)

from mac-pixel-clock-patch-v2.

I will probably need ti change some other stuff.. maybe i delete this again and make a new script for this..

I'm going to give it a look when I'm off of work

from mac-pixel-clock-patch-v2.

@Floris497 I dig more into your script and updated md5 checksum by

otool -t ${IOKitLocation} |tail -n +2 |md5 -q

Just pulled a request for you, and thks for the tip to expose md5 checksum from '(__DATA,__data)' section. :)

@Floris497 sorry just now saw this, let me know if I should try anything else, updating to the latest public beta now.

from mac-pixel-clock-patch-v2.

There will be a new patch file for the new file to be patched in 10.12, "coming this weekend brand new patch file"

from mac-pixel-clock-patch-v2.

@syscl Thanks for the dp3 supported patch. I can confirm that it is working with the 10.12 public beta 2 (16A254g). Please see attached screenshots.

from mac-pixel-clock-patch-v2.

@syscl what is it you do with patch v8? I can find the code but the perl line does not work.. Did not check for syntax though. It seems like the same code is now present in IOKit and CoreDisplay. Sadly I have no way of testing 4k at the moment..

from mac-pixel-clock-patch-v2.

Hm.. I see what you do now.. somehow my Mac Mini has a different CoreDisplay than my MacBook Air.. both running the same version of OS X from the same source reinstalled both of them and updated from db2 to db3.. so your patch first.. Apple has be working to recreate a lot of the display code it seems, I am now able to have 4k@30Hz on my mini without the patch and 4k@60Hz with the patch.. this was never before possible, I could get it to 40Hz.. Any specific reason to put so many NOP instructions before the jump? (Hope this info is interesting to you also 😃)

EDIT: apparently the macOS shows 60Hz.. but the monitor says 30Hz.. this is MST and the other one is SST both can do 60Hz. I will check later this week if the other one will go up further than 30Hz.

@Floris497 Interesting, I will see it later. Still busy these days...
