Can someone see my efi?

[Oski146]

Hello there.
I made a efi in 3 days. Phew.. but when i want to install the mac os installer is not showing up in the menu. Last supported os by my test system is highsierra. I wonder if i could install catalina on it.
My lan and wifi are not supported so i must use usb tethering to set it up.
Can someone see my efi and give me some advice on how to refine it?
iam using opencore and if its better to use other tools i appreciate your help

Hello.

I do not think your CPU meets the hardware requirements for Catalina. You may have to choose an older version of the operating system. As far as I'm aware the latest you can use is High Sierra.

If you decide to got this route then by all means Zip your EFI folder and attach it to a post. Then we can take a look at it for you.

I will move your thread to High Sierra Support.

(No EFI Zip was attached.)

Okay ...

Your syetem-defintion is too old. Try iMac14.2

To get started only use 2x UEFI drivers in the Drivers folder to start with - OpenRuntime.efi & HfsPlusLegacy.efi

Also disable the itlwm.kext to start with. I understand you may have no Internet because of this, but getting installed is more important first.

Enable the XhciPortLimit.kext.

Change the Misc/Security/SecureBootModel to Disabled.

I assume you have created a Legacy installation.

Test and see if you get further.

and yes its a legacy install.. thanks for the help and i will try my best.
EDIT: i will test now

You said in your first post that you were not able to boot the installer.
Please don't edit old posts because then they do not make sense to people reading the thread later on.

What is the "dmg" you are using?

I redownloaded high sierra now and i could boot up.. managed it to get it to work. Now i can boot into the installed os...
But at icloud login it says a server login error and i dont know how to get over this message. I was googling it but no answers at all. Its the first time i get this to work and use mac os
