patch problem about mac-pixel-clock-patch-v2 HOT 14 CLOSED

What is the output? it looks like there is still a version of 10.11.2 as a bak file, this may has stopped the script from overwriting the old backup.. if md5 -q /System/Library/Frameworks/IOKit.framework/Versions/A/IOKit outputs a7afb2dd9df1e4c48f12b4b52f7da212 remove it and try the patch again.

please let me know if that works

Hello. Same problem here:

---- BEGINNING MD5 HASH SUMS ---- version: 10.11.3 build:15D21

     otool IOKit: 422c441e207a011b355f712fc0ff7fba

That is really interesting.. What does md5 -q /System/Library/Frameworks/IOKit.framework/Versions/A/IOKit and md5 -q /System/Library/Frameworks/IOKit.framework/Versions/A/IOKit.bak give you? @LETRA it seems like your patch has worked because the code of IOKit has changed. If the otool md5's are different code has changed. The interesting thing is that the IOKit.bak file seems to be the one found in 10.11.2, i'm currently updating my computer to 10.11 so i can see it for myself, can you confirm the patch does not work while the code has changed?

from mac-pixel-clock-patch-v2.

There seems to be a little mistake in the script that won't let you use it, i'm fixing it as i speek (typ). quick fix is to run $ patch.command patch v6

EDID: patch now working as expected

from mac-pixel-clock-patch-v2.

I can confirm. I tried the update with the earlier version of the script and not worked. And I tried again running the latest version of the script and it has not worked.

from mac-pixel-clock-patch-v2.

It does not work with that command. The output is as follows:

Mac-mini-de-LETRA:~ LETRA$ /Users/LETRA/Downloads/IOKit-patcher.command patch v6
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 IOKit. be carefull
It might be wise to undo the patch before trying to redo it. using: /Users/LETRA/Downloads/IOKit-patcher.command unpatch
Do you want to continue? [Y/n] Y

This is unfortunate.. does the old script work? the problem i see is that the version of your IOKit backup is different to mine.. but the code in both patched and unmatched is the same.

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

the "IOKit: md5hash" line is different for every person (if it is patched), this due to a unique code signing certificate. but the IOKit.bak file must be the same.. but it is not.. your IOKit.bak has an md5 hash of "a7afb2dd9df1e4c48f12b4b52f7da212" which is the hash of the IOKit of 10.11.2.. it almost looks like an odd update by apple.. my update path was 10.11 -> 10.11.3 but maybe 10.11.2 -> 10.11.3 didn't change the code of IOKit because the code has not changed.. i can only guess they used a different signing certificate..

What version of mac mini do you have? the 2012 model has had some frame buffer updates.. with made this script unusable.. taking back the frame buffer kext from an older version of OS X solved this.. i would recommend reinstalling OS X.. A normal reinstall will take about 40 minutes to an hour.. i'm going to test this on my mini 2011 now.. see what happens..

On my mac mini:

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

When it is done updating to 10.11.3 i'll see if IOKit was updated or not..

very strange condition

EDIT after instilling 10.11.3 over 10.11.2
(see it did not remove the old .bak file.. because the newly placed IOKit is identified as unpatched it will not warn for the old IOKit.bak file..)

The interesting part is that the IOKit of 10.11.2 has a different hash, but the same code as the 10.11.3 IOKit.. this is rather odd.. can you run "patch.command test" i just updated the script again..

It works in all the ways i tested.. :/

from mac-pixel-clock-patch-v2.

Hi Floris. I restore OSX from my Time Machine copy. In this moment run 10.11.2 and I doubt update OSX & install the script until you confirm me that's all right.

from mac-pixel-clock-patch-v2.

I can confirm it works. I tested it on my 2011 mac mini, what model or mac mini do you have? the 2012 model has been subject to frame buffer changes that made the patch irrelevant not working.. I hope this is not the case with 10.11.3. What you can see is that your IOKit was correctly patched: otool IOKit: 422c441e207a011b355f712fc0ff7fba this checksum is the same as mine and at my machine this defiantly worked.. If we would be able to confirm the patch does indeed not work on your system then you must try to update to 10.11.3 run the patch and test if it is working. if it is not working you should copy either the Apple /System/Library/Extensions/AppleIntelFramebufferAzul.kext or /System/Library/Extensions/AppleIntelFramebufferCapri.kext depending on which one is used for your mac from the Time Machine backup, (it depends on the Integrated graphics you have). Also if you have dedicated graphics This patch works only for integrated graphics. the 'old' one still has support for Nvidia and AMD although i don't usually update them because many people don't want them to be patched. this patch will get it's own Nvidia and AMD patch in the near future.

Everything is right now. Thank you very much for your attention Floris.

Great :) I'm happy it works now!

If @aren13 can confirm his version works too I can close the issue.

Ok so I had an earlier patch from V1. 10.11.2.

So I deleted the old IOKit.bak, and reran the script.

Did it work? This is on a MacBook Pro Mid 2012. I will confirm later as I am not using a higher resolution monitor currently.

Yep that looks totally fine :D As long as nothing weird has happend and otool IOKit and otool IOKit.bak are different the patch has been successful :)
