    IOUSBHostInterface it gets to this point and keeps restarting

    • Try using this command as the last CMD command-
      VBoxManage modifyvm “YOUR MACHINE” –CPU-profile “Intel Xeon X5482 3.20GHz”

      Can you share your system configuration?

      • Bradley Cooper Reply

        i have used that command otherwise it just freezes, and are u talking about my actual pc configuration or VM?

            ah damh okay ill give that one a shot

  2. I’m having the same issue as Bradley.

    CPU: Intel(R) Core(TM) i7-8750H CPU @ 2.20GHz
    GPU NVIDIA GeForce GTX 1050 Ti
    RAM: 8038 MB

    I’ve tried all the provided CPU profiles and they all do the same thing.

    • Try shifting USB Drive from a USB 3.0 port to USB 2.0 port and then re-try!
      This helped fix IOUSBHostInterface error for a few of our users.

      • Mine was actually defaulted to USB 2. I changed it to 3 just to test and it got further (?) seemingly.

        • Did it stuck on the last lines? Try restarting your computer and disabling your firewall and windows defender.

          • It doesn’t stick, it just starts the entire process over. Here’s a GIF that shows exactly what is happening.

            https://imgur.com/a/nFCkXrA

            This is with defender and firewall disabled.

          • Ruby

            Well, I really am not sure what the issue is. It sometimes happens that this method doesn’t work for some users.
            ALternatively-
            1. Try using a VMDK file instead of an ISO file
            2. Instead of using Virtualbox, try on VMWare

          • Okay. Thank you for taking the time to help me. Much appreciated. =)

          • Eric Strom

            I had the same issue where it would get stuck validating root dmg. I was able to fix by adding the Catalina VMDK from here as a second hard drive and booting from it instead of the .iso.

            https://techrechard.com/download-macos-catalina-vmdk-for-vmware-virtualbox-10-15-7/

            Interestingly, my VM seemed to speed up once I changed the DMISystemProduct to MacBookPro14,3.

    I am trying to install High Sierra and having problem.
    When I reach to Disk Utilities and click on the Install macOS as shown in the instruction, I get the message that the file is damaged and can not be used for install.

    I have downloaded the ISO from MediaFire couple of times and tried but every time I get the same message.

    Please help.

    Thanks.

    • If the ISO seems to be not working, please try with the VMDK file.
      It sometimes shows the file as corrupt depending upon the desktop configration.
      I tried working on it again, and it worked well for me.

  4. i get Configuration error: Querying “UUID” failed (VERR_CFGM_VALUE_NOT_FOUND). when starting
