[GUIDE] Intel HD Graphics 5500 on OS X Yosemite 10.10.3

[cochubanyiezz]

Try 0x16260006.

After do some trial and error, I found that...
If I use these values:

• 0x162b0004 – Broadwell GT3 (MacBook Pro) (Intel Iris Graphics 6100)
• 0x16260004 – Broadwell GT3 (MacBook Air) (Intel HD Graphics 6000)

I must press the power button twice to turn on the display (invoke sleep and wake).

But, if I use these values:

• 0x16260005 – Broadwell GT3 (MacBook Air) (Intel HD Graphics 6000)
• 0x16260006 – Broadwell GT3 (MacBook Air) (Intel HD Graphics 6000

I can boot directly, normally, into desktop without needed to do anything..

And now, I'm using 0x16260005 in my config.plist.

Do you know what is the difference between that 4 values?
Also, what is the difference between 0x16260005 and 0x16260006? Since I can boot normally with these values, but I didn't see any differences.


ps.: sorry for my bad english

The difference is in the framebuffer configuration data attached to each value.

Also, what is the difference between 0x16260005 and 0x16260006? Since I can boot normally with these values, but I didn't see any differences.

To know the difference you'd have to analyse the differences in the framebuffer data in both.

Hi all i stuck here-
(3) Extract BIOS Settings from a BIOS file.
Download UEFITools from https://github.com/LongSoft/UEFITool/releases
Open your BIOS file with UEFITools.
Find the module labeled with Setup and extract the PE32 image section in this module as a binary file.
I have extracted my bios to desktop on windows machine with HP Notebiik system BIOS. So I have got 5 bin files! Which one to open? I cannot find setup modul plz help.

You were close, export SetupUtility and extract it with Universal IFR Extractor will get your result.

Thanks, but alas(
setup_var is not recognized by UEFI shell, help says setvar for that purpose. Screenshot inside.

I have done it like you said. And yes
Setting: IGD - DVMT Pre-Allocated, Variable: 0x18C {05 91 AC 02 AD 02 00 0A 34 12 8C 01 04 10 00 3F 00}
0x69619 Option: 0 MB, Value: 0x0 {09 07 E0 01 00 00 00}
0x69620 Option: 32 MB, Value: 0x1 (default) {09 07 E5 01 10 00 01}
0x69627 Option: 64 MB, Value: 0x2 {09 07 E6 01 00 00 02}
0x6962E Option: 96 MB, Value: 0x3 {09 07 E9 01 00 00 03} that is correct value, but UEFI cant find thaat string((

Also its not very easy to understand how to open- DSDT?
So we can use DSDT/SSDT to inject AAPL, ig-platform-id. 0x16160002 is working fine.

Open your DSDT, find Device (GFX0) or Device (IGPU) or Name (_ADR, 0x00020000) and add the Device-Specific Method.
Im coming closer but need some help, also I think GUIDE should be updated with PROPER info.
BTW EFI shell 2.2
EDKII
UEFI 2.40

After several day using yosemite on my laptop, I got not responding problem and screen blinking problem...

Screen blinking was happened after more than 1 hours I'm using safari for browsing, and then all windows opened blinking immediately. When I click apple logo, it's suddenly closed because all windows is blinking. Is it garbled screen that Austere.J mention at first post?

About not responding problem, it's rare happened to me. When it was happen, I checked the problem with Console app, and I got message that the not responding problem happened caused by gpu hang. Is it called screen freeze problem? The screen is not really freezed because I still can see the beach ball cursor spinning, and I still can move the pointer, but I can't interact with anything in the screen, not responding with any click...

I attach the log related to not responding problem that I got from console app...
