    Disable Acpi > DSDT during install.


    Disable Virtualization

    Install latest BIOS for your Device https://pcsupport.lenovo.com/u…d-t530/downloads/ds029246


    Try another SSD


    I installed BigSur 3 days ago without any issues. You tried 4 different EFI Folders alreasdy and none of them Work… something must be wrong.

    Dear @5T33Z0


    Not Work


    i am already changed my ssd but same result .



    The only difference between your notebook and my notebook is just whitelisting or modifying the bios.


    My point is that if it doesn't support, then no operating system will support Mac. But I am now using Mac OS Catalina 10.15.7



    I noticed that after whitelist then make EFI are not supported on my PC


    EFI doesn't support those who have modified buses on my board so I told you once before that my bios is not modified I believe it is only for wifi card but what is the reason for so many differences in the system.


    I have faced similar problems before


    I don't know why modified bios EFI don't work my pc, so I thought maybe I didn't work because I wasn't whitelisted.


    1. For installing macOS NO modified BIOS is necessary!!!

    2. Just update the regular BIOS to the latest Version!

    3. A modified BIOS is ONLY necessary for whitelisted Networkcards!

    4. If you want to UNLOCK your BIOS you can use 1vyrain which is a software jailbreak.

    @5T33Z0


    Bios Already Updated the latest Version! 2.77



    Well, if I don't change my wifi card after unlocking the Bios, I mean if I don't use wifi card for macOS after unlocking the Bios, can I use my existing wifi card in windows??

    Of course. First of all it's a compatible wifi card, 2nd of all, if the whitelist is removed there are no restrictions for the wifi cards anyway.


    There's a thread for making intel cards work, but it's experimental and only works with some cards and is in german of course: Intel Wİ-Fİ: es wird spannend!


    But like I said before, Installing MacOS doesnt require the BIOS unlock.

    PDM This is an IVYBRIDGE CPU, NOT SANDYBRIDGE! For BigSur you need to to change to 11,1 but I think 11,2 or 11,4 is more apprpriate fot i7 CPUs!

    Zitat von antukst

    NO JUST COPPY AND PAST AND USE

    WRONG. You need to change the SMBIOS for BigSur to MacBookPro11,1 or 11,2 or 11,4 check everymac.com for CPU similar to your model in freqeuncies

    Please add verbose output to boot-args:

    NVRAM > Add > 7C436110-AB2A-4BBB-A880-FE41995C9F82 > boot-args: -v debug=0x100

    Hardware

    I updated to the latest beta of BigSur (20B5012d) with no problems.

    Yes. That's the build number


    PDM How did you get it - through Software-Update? I tried that but it said "You are already up to date" but it's still the previous beta…
