THANKS for this amazing project!

Nice,as upstairs operation it's ok after reboot!

[ricardovf]

It also worked here! Many thanks for this patch!

No longer working on my machine, just updated from 10.13.5 to 10.13.6 last night.

[danieltroger]

You have to manually specify the version. Run the command in Terminal and supply patch 4 as argument

Sorry, patch v4, please see the uppermost row in my original post, after "Patching:"

[ikseoj]

@danieltroger That worked great specifying patch v4. Thank you!

[pitichampi]

Works perfectly with this version :) Many thanks !

[gabtrek]

Many thanks for this patch, you keep me from switching to Windows. But with the new Macbook "Pro" heat throttling I think it's going to happen anyway :p Thanks again and keep up the excellent work

[xzw219]

@danieltroger How to manually specify the patch version Thanks！

[danieltroger]

See above. For the lazy: cd to where you have the patch and execute ./CoreDisplay-patcher.command patch v4

[danieltroger]

@gabtrek: you can try installing windows as dual boot and use it for a week, you'll eventually swim in your vomit from my experience. Alone the thing that windows randomly doesn't boot or shutdown because it's installing updates you can't turn off makes up for some inches...

And thanks again for the patch, it is truly amazing. I love 4k.

[rzdev]

It works!! Many Thanks!!

[Meikul]

@danieltroger Can you post a screenshot of your SwitchResX configuration?

[danieltroger]

@Meikul

[jb107502]

@danieltroger Thanks for adding the info on the patch v4, I got it to work.

[LatteCat]

Great!

[szapata427]

does this work for macbook pro 2017?

[danieltroger]

@szapata427 I think it depends on your graphics card configuration. For the builtin intel HD-graphics it should work, AMD is not supported I believe.

[Floris497]

Why would you need this on a 2017 model?

[szapata427]

I connected my Samsung 40" tv (MU6290) via USB-C to HDMI Hub (Hyperdrive) to my 2017 macbook pro and it is only outputting 30hz. Not sure how to get it to output 60hz. Thanks

[Floris497]

Ah, I'm looking at specs from this device and they are only saying HDMI 4k if they don't list either 4K@60Hz or HDMI2.0 this usually means it is HDMI1.4 and not capable of 4K@60Hz.. so it looks to be a hardware limit (Apples own adapter also does NOT have HDMI2.0)

[Jensilein]

Hello, maybe someone can help. Before everything worked fine. Today I have upgraded to 10.13.6 and applied patch v4 afterwards. Output then was "The code of CoreDisplay changed, the patch was probbably succesfull." But it doesn't work. MD5 is:

---- BEGINNING MD5 HASH SUMS ---- version: 10.13.6 build:17G65

otool CoreDisplay: 7adbf5c02667db07dc8b48a22de8e642 otool CoreDisplay.bak: 20f0d2491e9370d3d74d25740aa855ba CoreDisplay: 0fe7a59d283bc692cbaa9fcef98dfc74 CoreDisplay.bak: e9698a0df0f68ab90f6ad0f870bf8833

---- ENDING MD5 HASH SUMS -------

@Floris497: Can you help me to find a solution?

[marcink]

@Jensilein, this looks like the output I saw on my MacBook Air. Than I followed the instructions in first post to apply patch v4: ./CoreDisplay-patcher.command patch v4

I got a bunch of warnings while the patch was being applied:

An backup file already exists, if you force this patch on an already patched version you will loose the original backup!
This will lead you to reinstall the OS if you loose a working version of CoreDisplay. be carefull
It might be wise to undo the patch before trying to redo it using: mac-pixel-clock-patch-V2/CoreDisplay-patcher.command unpatch
Do you want to continue? [Y/n]

The code of CoreDisplay changed, the patch was probbably succesfull

But the patch worked. As always, you need SIP disabled to apply the patch.

IMPORTANT: make sure you have a way to recover your system if the patch does not work - this would likely mean reinstalling OSX from recovery..

[Jensilein]

@marcink, Thanks for your reply. I finally solved it. The solution was about SwitchResX. I had to create a new OSX user, login as the new user and then to install my individual resolution. That was the final workaround :-)

Here is my session from trying it on Mojave. I'll be interested in an update to work with Mojave
