Hello everybody !

 

I followed the very good guide about the Latitude 7440 Installation for Catalina 10.15.4 and... all is almost working !

 

Maybe, you can help me, i'm completly stucked .

Contrary to the guide I followed , I don't have a Broadcom inside my laptop, this is another Wireless Card which seems to be supported : 

 

this is this one : Dell     DW1601        ½Min PCIe   168c-0034   AR94624      A/B/G/N/AD   N  N  N   Y   Y  Y    N    (=AR5B22)

 

I try different ways to install this one without success. I used the package that is provided in the guide :

 

EFI 10.15.4 e7440 V2.zip

 

I don't know where I'm wrong... could you please help me ? 

 

Thanks

Hmmm, i tried Clover r5107 and clover r5117, I have a new problem now.

When I boot on the USB key , I m not able anymore to install ( 1st boot to go to the utility disk aso..)

Hello Hervé,

Thanks for your help.

 

Version of Clover is : Clover_v2.5k_r5103

Version I try to install : Catalina 10.15.4

 

Will try to put the option -disableigfxfirmware ( but first I have to find where I have to set this option ^^)

 

Hello guys,

I would like to share my trouble.
I try to install Catalina (last version 10.15.4) on my 7490 (i5 version)

I followed the guide from Hervé ( tu es Français ?) but I had the same problem than Mahdiano (I was not able to boot to Setup the OS
after the second reboot).
So I removed the DSDT.aml file as Jake Lo suggested and then I added the 7490_BrightnessFnKeys package.

Now the installation is going farest but I'm not able to boot the MacOs

 

I had the following message about GFX ( IMG_4007.jpg)

 

Then i have a KP ( IMG_4006.jpg)

 

Could you please help me ? I have no more ideas now..

 

Thx
