[Guide] Booting The USB Installer Using OpenCore

[Feartech]

Hi Guys

I resolved the issues that mentioned above (AppleKeyStore ... Operation failed) by upgrade kext to last version. But there are new issues now, the boot process was freeze as attach, the CPU fan is in high speed (CPU is running).

Any suggestion ?

what version of macOS? where is your zipped EFI?

Hello!

I have started with Lenovo T460 from the beginning just for learn, just for play. I have installed ok Catalina and Monterey.

I see main topic was edited on sep 17 2023. But EFI files are updated to 2023?
Do I need to update opencore version or kext files ?

you don't need to fix something that is not broken

you will only need to update your files if you are planning on upgrading your macOS version

as you are already on Monterey then there is no real need to update

gibMacOS - the Python script rather than the batch file, does work. I've just used it.

I guess you are downloading from Windows?
