E7440 HS Installer Graphics Problem

Hi everyone,

 

I got a E7440 reently and wanted to install High Sierra on it. I've done it in the past on this website with an E7240 so I thought it would be straight forward on this laptop too.

 

I've made the Clover and HS usb sticks.

 

I've copied over HFSPlus.efi and APFS.efi to the drivers64 so Clover can see the HS installer usb.

 

I am getting the following graphics glitch/error when booting into the installer:

The installer is working as it then goes to the main installer menu so it's a graphics related bug.

 

The cpu is a Core I5-4310U @ 2Ghz .

 

I have not touched the config.plist from Jake Lo's E7440 clover pack so it's weird why this is happening.

Well-known 2nd stage/final stage boot glitch that affects systems running on Intel iGPU since Yosemite or El Capitan (can't remember exactly). Discussed for years and fix widely available on various forums, including ours. Please run a search to obtain the High Sierra patch.

I had to enable Legacy boot options and this patch:

Quote

In: IOGraphicsFamily Find: 0100007522 Replace by: 010000EB22

was already in the config.plist.

 

Now it seems to be working fine. I will run the installer and see what happens.

 

Thanks for pointing me in the right direction, @Hervé
