Hi Jake, now I'm trying to install El Capitan on the same laptop, Dell Latitude E7270 Core i7 DW1830. I use the same EFI that was successfully used in installing High Sierra. But when the USB installer is used to install, the thing that appears is: This version of Mac OS is not supported on this platform! Reason: Mac-473D31EABEB93F9B (as shown in the picture).

 

Then I change the SMBIOS in config.plist by selecting type 12.1 (as shown in the picture) and after that the USB installer can run. But then it stops as seen in the picture.

 

Please help.

Ok. Thank you Jake. Greetings from my beautiful country, Indonesia.

should I update all kext other than those mentioned above?

Thank you for your help. I think everything is ok now. Jake, I have one question, which one is better for Dell Latitude E7270 : El Capitan, Sierra, High Sierra or Mojave?

Thank you Jake. Excellent. Now the display is full. But, when I press Fn + F11 or F12 the Brightness can't work. What should I do next?

 

If I remove -igfxvesa from my boot arg, so the mac boot process will stop at this view

Debug file

debug_14993.zip

I have done several kinds of ways but I haven't got debug files.
is this 4 mb display because there is no DSDT file in the E7470_Mojave.zip folder?

This is my debug file that I take from IORegistryExplorer app

There are 3 things that might be a problem

I have finished to do it, but the problem still appear. Still got 4MB of display.

Thank you for your help. I have successfully installed Mac on my E7270. But now, the problem is the display. I only got display 4 MB after setting it in clover configurator - ig-platform-id : 0x19160000.

I have followed all instructions

- BIOS settings
- Clover setting during installation
- Use Bootpacks E7470_Mojave.zip

But it's still stuck in the picture above

Thank you. But, is the Bootpacks for E7470_Mojave.zip same for E7270 type?

 

Please help me. I have the same model of my laptop, but my BIOS version is 1.20.3. My bootable stuck on panic. Please.
