E7270 Ultrabook i5

Recommended Posts

Because when I use High Sierra (even Mojave), there are several applications (at least 4 applications until I decide to change to El Capitan again) that I use to work with El Capitan on a previous laptop, which cannot run properly in High Sierra (even on Mojave, there are around 5 applications that cannot run properly). And this is a specific application. Not an easily updated / upgraded application.


I really apologize if you feel like spending time on this issue to helping me.

boot to Clover, press F4.

Attach your USB to a working system, compress and attach /EFI/Clover/ACPI/Origin folder

I'll need to patch your files unique to your system

Hmm, those are not the files I sent you for El Capitan. The Config and ACPI /Patched folder are not updated.

Have you tried with those files first?

Yes, I already used EFI El Capitan that you sent both on the FD Installer and on the SSD that has El Capitan installed. And both of them can't boot normally to the desktop. Even if I use boot arg -igfxvesa and / or -no_compat_check. The result is like the picture I sent earlier.




Why do I use the current EFI, because it can install and enter the SSD installed El Capitan. But the problem are :

1. I have to use boot arg -igfxvesa to boot until it enters the desktop.

2. The display is still 4MB after enter the desktop.


Maybe this can help a little :

Ok, try this, replace into /EFI/Clover. Files patched from your Origin folder. You can continue using the kexts folders as is, but maybe remove NoTouchID.kext.

Don't need to generate SSDT.aml, Clover Config has pluginType enable which does the same thing.

Oh God, I'm very grateful to you Jake. Now it works and booting is very fast entering the desktop. Just a few seconds. The display is now full to 1536MB. I am very happy. Thank you very much, Jake. You are the best.
