Hi Pike, the tool seems to work well. A minor issue, though: the display port (where I connect 27" Apple Cinema Display via DP>miniDP adapter) still is shown as port usused. As a matter of fact I have HDMI audio via HDMI port, but not from Display Port. Could it be related/solved by AppleIntelFramebufferAzul.sh?
The hardware: GA H81M-HD3, intel i3 4330

When i changed the AppleIntelFramebufferAzul.kext on my Macbook Air 2013 i got some weird behaviours.

frame buffer size: 36MB and the BIOS mem to 64MB will work for a little bit it shows 4k but with some weird distortion and when i use my internal display i get really strange distortion

frame buffer size: 36MB and the BIOS mem to 32MB will lead to a kernel panic

frame buffer size: 24MB works but this is too small for 4k
frame buffer size: 24MB and the BIOS mem to 64MB will lead to a kernel panic

What are the correct settings for this model? my HD5000 uses this frame buffer:
[11] : 0x0a260006 - Haswell ULT Mobile GT3

Is this because the edit to the kext was not right or the GPU did not support the settings?

After patching the Framebuffer and deciding to change platformID they become the same:
0x0d220003 - Haswell CRW GT3

after
0x04120004 - Haswell GT2

sorry for my english :)

Neither High Sierra nor Mojave can work

In the screenshot below you can see the framebuffer says "(port 7, DisplayPort connector / port unused)", but if I try to change a port, it says "[ 4 ] port unused (VGA connector)"

Which port is unused, I guess the VGA connector.

After patching the Framebuffer and deciding to not reboot the system immediately the following error occurs:

Once again thanks very much Pike for all the effort you put into this!

Hi,
I know this quite unrelated, but I can't find any info about editing parameters of AppleIntelSNBGraphics.

The Apple HD3000 driver is limiting the output in HDMI to 1920x1200 max.
But, after seeing this https://discussions.apple.com/message/25831860#25831860 , I'm pretty sure that I can apply the same "patch", increase the framebuffer size, to get to my bigger resolution (2560x1080).

The problem is, I have no idea where to begin, where to search. I already spent hours searching that on internet but no luck.
So I thought maybe you know where to begin. I'm not asking for the solution, I just need to know the procedure to reverse engineer that binary file.

Anyway, thanks for your work.

when running this on capri, choosing even numbered selection from the options (i.e choosing 2, 4, 6, 8, 10 or 12) picks the incorrect offset and the report is then bad:

here is 4 as an example:
