Now to Run macOS Installation Script
First, make a Target Directory to hold all the Stuff Downloaded during Setup:
```
mkdir /[PATH/2/VMS]/macOS
```
Replace /[PATH/2/VMS] with your current VirtualBox VMs Path in the above.
And store it into the Target:
```
mv ~/Downloads/macos-guest-virtualbox.sh /[PATH/2/VMS]/macOS
```
But if you are in Trouble to Find it out on Terminal then See: How to Access Downloads Folder from Browser.
Next access it:

cd /[PATH/2/VMS]/macOS
```
Give execution permissions:

```
4. Making Virtual Disk

Now Make & Format Installation Virtual HD
(This Step is missing in the current Script and it’s my Personal Hacking Contribute :)
So Power Off the Machine and access Settings >> Storage
Then Create a HD of about 40Gb and Pre-alocated Full Size (That’s just as I did…)) br /> First, Choose the “+” Add Hard Drive on Top-Right:

Then Create on Top-Left:

Confirm the Default File Type:

Check the Pre-allocate Full Size:

Select and to Attach it:

And you are Done! :)

Re-Start the VM.
And after Launch the Disk Utility:

Next, Choose the created Disk and Format it as HFS+:

Last, let’s go Reboot your macOS VM!
4. Installing macOS

So after Re-Start follow the macOS Installation Wizard

Choose the Language:

Then Reinstall OS:

Again confirm for “Install macOS Catalina”:

Agree to the License:

Choose the created Hard Drive:

Take a Break of about 30min while the System is Installing:

Last, after Automatic Re-boot the Setup will be achieved in some Minutes:
5. Configuring macOS

After the successfull Setup easily make the macOS Configuration
Simply follow up with the Wizard:
Then Read the POST-INSTALLATION SETUP at the Bottom!

ESPECIALLY RELEVANT: After the Installation is successfully achieved you should Manually Detach the Installation Drive.
So go in Settings >> Storage and Remove All but the OS Disk that you have created in the Former Step!

Finally, to achieve this Setup after Re-Booting again you need to Access on the Top-Left Menu Choose Startup Disk and Switch to the Installation one.
This to be Sure your VM will follow to Boot Up also if some Settings is changed.
