nice!

to create a matching Display file you need to know the display vendor and product id.

the file below will not go to resolution 1920x1080 but is an example

so this will show you to figure out the right file names...

$ ioreg -l| egrep 'EDID|DisplayProduct|DisplayVendor'
    | |   | | |   "FeatureControl" = {"Watermarks"=1,"RenderStandby"=1,"GPUInterruptHandling"=1,"DPM"=1,"MaximumSelfRefreshLevel"=3,"Gamma"=1,"PowerStates"=1,"IgnorePanelTimings"=0,"UseInterruptFilter"=1,"SpreadON"=1,"CachedEDIDDisable"=0,"FastDisplayDetectDisable"=0,"FBC"=0,"SetRC6Voltage"=0}
    | |   | | |       "DisplayProductID" = 738
    | |   | | |       "IODisplayEDID" = <00ffffffffffff0030e4e2020000000001140103801f1178ea33859956559127175054000000010101010101010101010101010101018025408060841a303020350036ae10000018401f408060841a303020350036ae10000018000000fe004c656e6f766f0a202020202020000000fe0031363030783930300a2020202000c7>
    | |   | | |       "DisplayVendorID" = 12516

"IODisplayEDID" = <00ffffffffffff0030e4e202

hex number is used for file names

decimal numbers are used in the DisplayProductID-xxxx file

30e4 = vendor ID
e202 ->flip bytes = 02 e2 = productID => 2e2

convert 2e2 from hex to decimal = 738
convert 30e4 from hex to decimal = 12516

$ cd  /System/Library/Displays/Contents/Resources/Overrides
$ sudo mkdir DisplayVendorID-30e4

$ cd  /System/Library/Displays/Contents/Resources/Overrides/DisplayVendorID-30e4

$ cp some file to this DisplayProductID-2e2

$ cat DisplayProductID-2e2

which next Lenovo T4x0 or X2x0 will be your next hackintosh?

tluck · February 28, 2016

@tetonne - not sure - what are you thinking?! my company changed the options for companied provided laptops - so not happy with the choices at the moment.

@oxygen427

i am not sure where you got the Vendor and Prod id? because from your ioreg ...

| | | | | "IODisplayEDID" = <00ffffffffffff0030aea340000000000c190104951f1

VendorID=30ae

30ae (hex) = 12462 (dec)

ProductID= a3 40 flip => 40a3

40a3 (hex) = 16547 (dec)

so

folder is DisplayVendorID-30ae

file is DisplayProductID-40a3

in the file

1) change the ProductID to 16547

2) change the VendorID to 12462

and add 1920x1080 resolution --- so

$ cat DisplayProductID-16547

Thank you sir @tluck

karlamba · March 1, 2016

@tluck

hi, thanks for your very detailed guide.

My T420 works well, but I'm using a nano USB wifi adapter instead of internal wifi adapter, and the internet speed is not very well. I'm planning to replace the stock intel adapter by a broadcom adapter, such as BCM94322HM8L (native OS X support?). Which wifi adapter are you using? Can you give me some selections with good performance like stock intel adapter?

artheros wifi is perfect for me, installed modded bios and finally have wifi fully working... all takes not longer than half hour to update modded bios and switch wifi cards...

I've bought:

AR5BHB92 HP Pavilion DV6-2XXX FVGW6837

it costs me around 10$ in Poland...

chears!

PS - Guys it is really nice and wonderful that this topic is life for so long time and still there is always something new here...

trifero · March 2, 2016

Hello, tluck. Is ir possible to update the new package to an already installed system without any problem? How do you recommend to perform such task?

Thank you so much.

marcocontra · March 2, 2016

Hi guys! I've a problem.

I'm trying DW1520 BCM4322 Wireless AGN Half MINI PCI-E card (chipset Broadcom BCM943224HMS) on my T420 (I know, but it's a wrong purchase..).

Everything worked fine for 2 weeks, out of the box. Now suddenly I can't connect to my ADSL router or others networks. I can connect only to a 3g router Huawei, but I have no internet access.

What do you think? Is the wifi card broken?

Sorry for my bad english.

Thank you.

tluck · March 2, 2016

@trifero - yes. just follow part 2 of the guide. mount the ESP and update the CLOVER and BOOT directories from the zip.

trifero · March 2, 2016

Narcocontra, try this. delete all prefered in wifi preferences.

Already done.. nothing change..

I suspect an hw problem, on win10 just the same problem now!

trifero · March 2, 2016

Really weird.... don´t you have an Usb wifi module, just for try?

trifero · March 2, 2016

@trifero - yes. just follow part 2 of the guide. mount the ESP and update the CLOVER and BOOT directories from the zip.

All done. Worked like a charm.

marcocontra · March 2, 2016

@trifero - Mounting another card (Broadcom BCM94322HM8L) all work perfectly.. I trying to contact the shop for changing the DW1520 in warranty.

Thanks for your support!

it´s weird, but i have seen that so many times. Since Cheetah. When Os X says no, it´s no. Made me mad so many times. Often, when you disable wifi security (no password) , works like a charm. really don´t know why...

parcox · March 3, 2016

Hi all,

I'm planning to upgrade my screen to 1600x900. Need an information what to edit here? Clover config.plist and DSDT or anything else?

vusun123 · March 3, 2016

Yeah I have the system up and running now, from my internal screen with right resolution. Sound and ethernet work as well now.

Only issue, I get a KP after a few minutes.
panic(cpu 2 caller 0xffffff7f807ff1df): No HPETs available...CPU(s) configured incorrectly
Debugger called: <panic>
Backtrace (CPU2), Frame : Return Adress
and after that a lot of computer language, which probably is the adress of where it got stuck or something.
I'm going to try changing stuff in bios first, turning off hypertheading etc, maybe it works maybe not, I'll post updates.
I'm still running original UEFI/BIOS by the way, because I wasn't planning yet on changing my wireless card.

I think some things in your DSDT aren't the same after all, but the namechanging thing did work for the rest. Only problem now is that I do not have any knowledge of modifying DSDT's...

tluck's DSDT doesn't have the HPET patch, so it's normal to get KP like that. Remind him to patch it

tluck · March 3, 2016

@parcox -

i recently went through this same procedure. so when you change your screen to 1600x900 it is very important that your change the cable with new inverter too. the inverter is specific to the screen size.

the only thing that you will need to change the config.plist file. the DSDT is the same for either size.

@vusun123

hmm. distortionmusic posted that note 3 years ago? well anyway the HPET device is patched to add IRQ

// tjl-fix HPET likes 4 interupts - change

IRQNoFlags () {8,11,14,15}

what is missing?

trifero · March 3, 2016

Hi all,

parcox, to update to a 1600x900 it´s unbelievable in usability. I had first a 1.366 x 768 one, and when a I moved to a 1600x900 i really got impressed.

trifero · March 3, 2016

I have the possibility of buying a X220 really cheap. I think that it´s easy to install Os X , Based on what i have read. Anyone have one of these? What do you think?

tluck · March 3, 2016

@trifero - seems that there are plenty of folks with the X220 - using the exact same stuff - dsdt, config , kexts from the T420 on the X220. pretty much a smaller version of the T420 in essence.

Thank you so much, tluck. I think i´m gonna buy it, to take it with me the nights I have to work. It is in really good state and for 145 euros.

scoobaspeaz · March 4, 2016

I am new to the hackintosh way of life and I have a T420 here I'd love to do this to. Are there any prebuilt images I could use or does anyone know of a guide I can follow to create an ISO to do this on a system that does not already have Macintosh/Hackintosh installed?

I am running Fedora Linux 23 and I do have a Windows 7 vm I run from time to time so any instructions based around building this on those two OS's would be appreciative.

trifero · March 4, 2016

Scoobaspeaz, maybe installing a virtual Os X with VirtualBox?

Lenovo ThinkPad T420 with UEFI Only
