/sbin/newfs_hfs failed with error 256

Could not restore - image data corrupted

Hi, please run ./macos-guest-virtualbox.sh troubleshoot and attach the resulting .txt file here.

I started from scratch. I had the error I reported to start with trice but now I got this

Thanks! Everything seems to be configured correctly. I'm going to take a wild guess and say macOS is attempting to perform CPU operations not supported by the Xeon E3-1245, resulting in memory corruption or other errors. See the documentation command about unsupported CPUs.

VirtualBox offers the following preconfigured CPU profiles: "Intel Xeon X5482 3.20GHz" "Intel Core i7-2635QM" "Intel Core i7-3960X" "Intel Core i5-3570" "Intel Core i7-5600U" "Intel Core i7-6700K"

You can set them manually with VBoxManage or add them to the script on line 657:

654    VBoxManage modifyvm "${vm_name}" --cpus "${cpu_count}" --memory "${memory_size}" \
655     --vram "${gpu_vram}" --pae on --boot1 none --boot2 none --boot3 none \
656     --boot4 none --firmware efi --rtcuseutc on --chipset ich9 ${extension_pack_usb3_support} \
657      --mouse usbtablet --keyboard usb --audiocontroller hda --audiocodec stac9221

Add --cpu-profile "PROFILE". You'll have to find a working profile with trial and error or you could delve deeper into macOS and CPUID settings and make a custom CPUID.

It worked almost flawless on my laptop

Why unusable:

My disk was full so I had to create free space and start over

It did not recognize started terminal(s)
I have a working Catalina VM. Feel free to close this issue!

Thanks. Since you're running Linux I heartily recommend creating or converting the virtual disk image to vmdk, installing and configuring OpenCore, and booting the image on QEMU/KVM. If you're running High Sierra and have a spare compatible GPU it's a world of difference. If you don't have a compatible GPU, QEMU and OpenCore still offers a few nice benefits, with the price being your time spent configuring them.
