  1. validate_root_image: validating rot dmg/Install macOS.app/Contents/SharedSupport/BaseSystem.dmg

    Stuck at this for 2 seconds then again the process starts from the beginning.
    Please help.

  2. When I press esc it opens the boot menu and not a command line to type Install.nsh. If I do nothing, the operating system starts up regularly
    What do I have to do?

  3. i have two prblms, 1st the icloud could not be accessed from system preferences. And 2nd the sound is not working.
    thank you……

    • The first part of the installation works but when the machine restart and after “install nsh” There’s the Apple boot screen which charging and it takes a very long time. It seems to be stuck at the end of the charging process but the “hardrive” seems to write. What can I do please ?

      Thank’s for your tutorial.

  4. Hi Ali, I noticed that your vitualbox boot image is 1.25MB while the downloads were all 384KB. Is this a new file that we should use? Thanks.

  5. At step 7, I start the VM and I just get a screen that says Virtual Box and stays there forever. I don’t think it is doing anything. Task Manager shows activity in 4 cores but no I/O on the hard drive where the VM is supposed to run. What can I do? If I shut down the VM, are there any changes I should make? I read about the corrections on the script but it seems you already updated the script. Please help.

  6. Same issue there, mouse is laggy as hell, and my machine is impossible to use.

    Any idea how to fix this ?

    Thanks in advance.

  7. Hi Ali, How do you fix the following error:

    BdsDxe: loading Boot0001 “UEFI VBOX CD-ROM VB1-1a2b3c4d ” from Pci Root (0x0) /Pci (0xD,0x0)/Sata (0x1,0xFFFF,0x0). And this: BdsDxe: starting Boot0001 “UEFI

  8. getting “this Mac has been used to create too many new Apple IDs” when trying to create a new account.

    when trying to use my actual Apple account, it says “This Mac is no longer eligble to create Apple ID accounts. Creat an Apple ID using a different device”

    there is probably an underlying platform ID that is being sent to apple and if lots of people are using this virtual box process and instructions, they would all appear identical Mac’s

  9. I’m getting the following error:

    Shell> fs1:\system\library\coreservices\boot.efi
    Script Error Status: Unsupported (line number 7)

  10. Also stuck at Step 7. I’ve followed all steps precisely. Used Geekrar’s images (noting that the Boot file is 384k instead of 1.25m as in example). When I boot the VM, I get a black screen in VirtualBox and it doesn’t move past it. I’m on a Dell Latitude 7400.

  11. “startup.nsh” is not recognised as an internal or external command, operable program, or script file. Faceing this issue pls help me on this

  12. Okay – installs fine using the instructions and errata people pointed out about the double dashes in the commandline script. Also, you need to enable 3D Acceleration for Display.

    Issues so far … Mouse gets laggy either with USB set to 2 or 3. USB 3 lets you use your webcams, setting it to 2 does not.

    And neither method gets you sound. I believe you need TonyMacX86.com’s UNIBEAST to do that. If anyone has good instructions on how to post-install Unibeast on Catalina … that would be great.

  13. Hi. I dont install Catarina. I make step by step. And after i start the machine, write this : BdsDxe: loading Boot0001 “UEFI VBOX CD-ROM VB1-1a2b3c4d ” from Pci Root (0x0) /Pci (0xD,0x0)/Sata (0x1,0xFFFF,0x0). And this: BdsDxe: starting Boot0001 “UEFI …….I dont know where is problem. Thanks for your feedback.

  14. Hello Ali, i followed the NEW method, and there are some inconsistencies in your process causing some issues. Everything up to step 7 is okay, but after the remove of Catalina ISO steps and restart, you say to run “install.nsh”. Did that but errors.It says fs1:\macOS Install data\locked files\boot files\boot.efi is not recognized as an internal or external command, operable program or script file, and does that for each fs (fs0->fs4).

    I don’t see how the boot image is loaded when the first hard disk is the Catalina ISO. In other people procedures, we see that the imageboot is an optical drive setup, and booted before the catalina image(ISO/VMDK).

    Below is the file sets in each FS, can you advise how to correctly start the “install.nsh”, maybe the VBOX setup is not correct? or something is out of order when copying files from boot image?

    FS0:
    Has folder \EFI\APPLE\EXTENTIONS\Firmware.scap

    FS1:
    long string\ boot.efi with a lot of .im4m files

    FS2:
    has file kernelcore

    FS3:
    has the usr,bin,sbin,Library,System,dev,tmp, etc..

    FS4:
    Has long string folder, with usr, var, Library & System folders only

    FS5:
    Looks to be the actual macOS install:
    Has sw, .HFS+ Private Dirctory Data, home, usr, Library, System, mnt,private,Users,Applications, opt,Volumes,etc..

    FS6:
    has 3 files, VboxApfs.efi, startup.nsh, install.nsh

  15. A small erratum:
    In “VBoxManage.exe modifyvm “MacOS Catalina” -cpuidset 00000001 000106e5 00100800 0098e3fd bfebfbff”, make sure there are two “-” before ‘cpuidset’, namely, the line should be:

    VBoxManage.exe modifyvm “MacOS Catalina” –cpuidset 00000001 000106e5 00100800 0098e3fd bfebfbff

  16. when i do the initial start of the mac os, the command line keeps going on a loop and never makes it to the language menu

  17. Hi Ali, thanks for the tutorial! Followed all the steps and managed to fire it up to the beginning of step 7, but I have issues with input:
    – Mouse pointer is super laggy, making it almost unusable
    – Everytime I press a key, the system seems to believe I pressed it for several seconds (or several times), which makes it impossible to navigate or input anything during this step.

    I’m running it on a Surface Pro 7 – i5 – 16 GB – 256 GB

    Any ideas what could be the problem, or how I could solve it? Thanks in advance!

  18. Installation went smoothly. However, I keep getting prompted to update to macOS 10.15.1 even after I have installed the update and restarted my VirtualBox. What am I doing wrong?

  19. On step 6 is the first line wrong.
    the correct one is:
    VBoxManage.exe modifyvm “Your Virtual Machine Name” –cpuid-set 00000001 000106e5 00100800 0098e3fd bfebfbff
    before cpuid you will need two — and is has to be cpuid-set and not cpuidset.

  20. Failed to open a session for the virtual machine MacOS Catalina.

    The virtual machine ‘MacOS Catalina’ has terminated unexpectedly during startup with exit code 1 (0x1). More details may be available in ‘C:\Users\perry\VirtualBox VMs\MacOS Catalina\Logs\VBoxHardening.log’.

    Result Code: E_FAIL (0x80004005)
    Component: MachineWrap
    Interface: IMachine {5047460a-265d-4538-b23e-ddba5fb84976}

    What to do?
