In this article, I’ll show you how to Fix EFI Internal Shell on macOS Catalina on VirtualBox. macOS Catalina is by far the most solid operating system for Mac users. It was released on October 7, 2019, and since then it has been in hands of thousands and even millions of people which include macOS installed on Windows. As the users and lovers of this macOS are increasing the questions and problems are also increasing.
Users like to explore and see features of the new macOS specifically on Windows. That’s easy to do with us. I’ve made a complete step by step tutorial on install macOS Catalina on VirtualBox and also install macOS on VMware. But similar to macOS Catalina stuck at Apple logo when installing on VMware, in VirtualBox, users encounter UEFI or EFI Internal Shell on macOS Catalina or in some cases it also appears as VirtualBox FS1 problem. Since installing macOS Catalina is new for most Windows users and that’s what not everyone knows about so here’s how to fix that.
If you are also one of the users who don’t know how to solve this problem, you are in the right place. In today’s article, we’re going to learn what s UEFI, what is Virtualbox and how to Fix UEFI Internal Shell on macOS Catalina on VirtualBox.

What is UEFI (Unified Extensible Firmware Interface?)
To better understand UEFI you need to know what is BIOS because UEFI has replaced BIOS. BIOS is the basic input-output system. It allows level software to reside in a chip on the computer motherboard. BIOS is what loads up when the computer starts for waking up your computer’s hardware components to ensure correctly during boot time.
It runs the bootloader to start up your operating system. BIOS goes through the post (power-on self-test.) This happens before noting into the operating system to ensure hardware configurations are valid and working correctly. BIOS has not advanced with the latest PC technology in the market because it has several limitations as it can only boot from hard drives of 2.1TB or even less and many other quantitative that leads UEFI to take place of BIOS.
UEFI still provides a way to boot into BIOS. Its firmware can boot from hard drives of 2.2TB (terabytes) even larger and due to using GPT partition instead of the MBR. UEFI supports secure boot which actually checks for the malware during the boot process and it supports networking features within the firewire.
What is Virtualbox
Virtualbox is a free open source project and it essentially emulates running a full physical computer so that you can run another operating system on a server. Virtualization is the process and Virtualbox is the application for making it. Such as we have a computer within the software that is the inside of it and no one can see that but the hardware of a computer is visible. In the same case with virtualization and Virtualbox. Virtualbox is visible but virtualization is the process and the inside part.
Fix UEFI or EFI Internal Shell on macOS Catalina on VirtualBox
When you encounter EFI internal shell you may see an error or a notice. Don’t panic because nothing is wrong with your operating system and there’s no huge case. This error can come due to many reasons. One of the primary reason is, at the first steps when you create your virtual machine, you have to apply the code to VirtualBox on Command Prompt, you had to close your machine clearly and then apply the code to your virtual machine. When you’ve forget that, the error may be likely due to that.
If you are stuck at this EFI shell you need to create a new virtual machine. If you are a beginner, check this link down below to create a new virtual machine. There, we have provided the easiest way by following a few simple steps to create a virtual machine.
The second most common reason users encounter this problem is because of Apple File System (APFS). APFS is Apple’s new file system for Apple products such as MacOS, ipadOSs, watchOS, TVOS, and other Apple products. APFS doesn’t work perfectly with a VirtualBox specifically with macOS Catalina. This may encounter this and may also appear some other problems too. If you have tried to install or update macOS with APFS on VirtualBox, you will be probably stuck in the shell. When you face such problems you need to download a boot the ISO from the APFS boot image and load a driver from that. After downloading you can boot to your macOS.
For solving this problem turn off your machine first. From the top click on the Close icon and click Power off the machine.
Go to the Settings of the machine. There, you need to add the APFS EFI Boot Image on the machine.
After you are into machine settings, press “Storage”, select the CD/ISO file and click on the CD icon at the top right of the settings and click choose “Virtual Optical Disk File”.
Go over to your files and select the APFS EFI Boot Image file, click “open” and a new page will open and click OK in the machine setting.
Type these commands there and when you are done press Ctrl-Q and then press.
echo -off load fs1:\EFI\drivers\apfs.efi load fs1:\EFI\drivers\AppleUiSupport.efi load fs1:\EFI\drivers\ApfsDriverLoader.efi map -r fs2: cd System\Library\CoreServices\ boot.efi
On this page just type exit and click enter.
Just hit Enter for moving forward.
After you continue, you just need to wait for a while and then you’ll be welcomed with a screen asking you about your location. After you select your country you will be asked some more details of you, which you can do easily. Set up however you want and click Continue.
