[ALGhackintoshh]

 

Hi everyone, I am trying to install catalina on my pc but each time during the installation when there are 2 minutes left (mac os extended) or 3 minutes (apfs) I have the error. I tried 2 different SMBIOS, the apfs format and mac os extended , and

updated the date in the bios . Any help is welcome (hope @MaLd0n and his friends will do)

 

Motherboard: Msi h61m-p35 (b3), cpu intel pentium g840, amd radeon 5450 graphics and 4gb ram. (i know its too old but i saw that someone successfully mojave on it).  THIS IS MY FIRST HACKINTOSH EXPERIENCE

EmuVariableUefi.efi

If you have windows you can use miniTool Partition Magic in combination with explorer++ to mount your usb efi and change files inside the clover folder. You can try getting the config.plist of your corresponding efi folder for your hardware and adding it to your usb clover folder as "config3.plist" for example, then in clover boot menu you select that file for booting.

you can just use "diskmgmt.msc" to mount the EFI partition.

Hi @MaLd0n apparently nothing works, I tried everything, I replaced the efi file with  my chipset s'one , I used the full patched dsdt, I used the right cpuid and the right smbios but the error is still present. I would like to try to emulate nvram but I don't know how to do it. Please help me (i know i have to use emuvariableUefi.efi but i have no idea of how) (ive downloaded it on github)

Can I completely remove that clover EFI and use my OpenCore EFI on the USB installer? Will it work?
