How to Update macOS Catalina To The Latest Version



While macOS Catalina is still in preview mode and even when it’s released, there will be probably some issues, as of now not one but lots of problems with every part of it. These problems are usually with every operating system when they are newly rolled out. In terms of fixing them, first of all, they are out of our approach, even if we could be do something, the problems are more than what we can offer to fix. Second, they are out of scope except which we’ve provided the instructions for. That’s only the single side of the scenario. Here’s how to Update macOS Catalina To Latest Version on VMware & VirtualBox.

The other side is that these problems won’t be there all the time. By the time more and more Mac users and non-Apple users will install Catalina on a virtual machine or on their actual Macs, more and more problems will be recognized and send to Apple. In result, Apple will send a software update that will solve those problems. This will solve most of the problems even those which you had problem with, doesn’t matter you did something to solve it or not. Besides fixing those problems, there are huge things which a software update does.

One of those important reasons for updating your Mac is a security vulnerability. While Apple is widely popular for its security but it needs more and more updates for strengthening it. Including these, there is a range of updates to improve the new and previous apps and features. For example, Apple improves the photos and fixed bugs and compatibility issue with SwiftUI in XCode 11 with the fifth release of macOS Catalina update. Let’s see how to Update macOS Catalina To Latest Version on VMware & VirtualBox.

  1. Hi,
    everything works fine for me in VirtualBox, system updates work fine with updating in AppStore, even without the script Fs1:\update.nsh.
    But I have trouble with passing through my iPhone as USB device. It is recognized in VirtualBox but as soon as I activate it, the mouse cursor gets sluggy in MacOS and the iPhone isn’t recognized.
    Would the update.nsh script help here?
    If yes: how can I execute it if pressing “Esc” during startup is showing me the BIOS and no command line prompt?
    Thanks.

  2. So I am on VirtualBox on an AMD processor. The base Catalina OS is working. For the Update, after updating my Catalina OS within the Catalina OS I restart the VM. After hitting escape, I typed Fs1:\update.nsh which is not getting recognized. Then I tipped update Fs1:\update.nsh and the systems runs some lines and stops at [EBI#LOG:EXITBS:START] (current time)

  3. I would really appreciate it if you made a quick update to this either on video or text. I tried the virtual box way of using this to update my version of Catalina to a newer version but I still got an error. My error occurred at the last step. When I typed update fs1:\nsh update it ran some script and stopped and never opened my instance of catalina, it just stayed on the last line of code.

  4. Hi, don’t know, if my previous post was received. Yes, I have tried 3 different boot images :

    Bootloader Update Image.vmdk
    Update.vmdk
    VirtualBox Boot Image [Geekrar].vmdk

    Some does not work, and some start system, not upgrade. I don’t remember exactly which one.

  5. Hi,
    I’m using virtualbox, sucesfully installed osx catalina, but can’t upgrade. Instalation is downloaded, and when I try restart, it stuck on boot error. I have tried different boot vmdk imagas, but it does not work.

  6. I am trying to update catalina 10.15.3 on Virtualbox, but on restart the bios can’t boot: it is stuck trying to read “boot.efi”. Anyone had this issue?

  7. “you need to patch your vmware installation AGAIN” — Can you provide link to patch? Having trouble finding patch… Looks like Dr Donk’s version is now removed from Git Hub.

  8. Got it working.
    You forgot to tell that after updating workstation pro to 15.5, you need to patch your vmware installation AGAIN.

    Then, boot macos and get the latest update. After the update is downoaded, Do Not Restart to apply immediately but click ‘later’ .
    Instead, do a shutdown of your macos, and tick the box that says to re-open any open window after restart.

    With the VM down, in the options tab of the VM, set the guest operating system to Windows 🙂 and start the catalina VM. It will not boot properly and keep crashing after a portion of the progress bar is filled.

    Shutdown the VM again and go back to the options tab. Now set the guest operating system back to “Apple Mac OS X” and the version to “10.15” (which was previously NOT available, 10.14 being the highest!).

    Boot your catalina VM and after login, the updater window will open automatically and propose to reboot your Mac to finish installing updates. Let it reboot to finish updates. You’ll be greeted with the apple logo and a progress bar keeping you informed about the update progress. Mine took about 40 minutes to complete.

    Once updating is done, the Mac will boot clean into macOS 10.15.2.

    Hope this helps, enjoy!

  9. First I updated to Beta 3. After the update and reboot it still wants to update to Beta 3. So I tried to get the official release (10.15.1) from the app store. It downloaded and installed, which took a long time. After reboot it seems nothing had happened. It still wants to update to Beta 3. Where did it leave all the updated files?
    By the way: using VirtualBox 6.0 on Fedora linux 31.

  10. I can’t update u.u, the VM restart like nothing is happen and show me the menssage of software update download again

  11. Hi, I did the steps to the letter, the update finished downloading and then the Mac reboots, but now it’s stuck at the Apple logo screen, and no progress bar ever appears
