Bootcamp on MacOS Catalina cannot format drive. Hi, I am a mac newbie (mac mini 2014) with a fresh 10.15.1 Catalina upgrade and I want to bootcamp Windows 10 alongside. Every time I bootcamp the win 10 ISO the process just failed at the very beginning with 'Could not format disk'! I have tried formatting my USB drive with other file system but. Both Windows and Mac OS X can see each other’s files, but they can’t write to the other operating system’s partition. Thankfully, there are ways around these file-system limitations. Third-party applications can enable write support for these partitions, while you can also share files in other ways. My process on Catalina was to restore to a clean version of 10.15.1 by deleting everything on the computer and reinstalling, then once booted into MacOS install Windows through Bootcamp, then restore everything from my Time Machine backup. Overall took 4-5 hours but everything is the way it needs to be now. To use BootCamp your hard disk must no have any partition. If you have one, first you should delete it, then recover that space for your main macOS (Catalina, Mojave), then start BootCamp assistant. With this procedure I installed Windows 10 in my MacBook Pro and MacMini. Oct 25, 2019 6:43 PM.

Mac users who choose to upgrade (or already have upgraded) to Mac OS Catalina (10.15.x) or Big Sur (11.xx.x) will need to uninstall all 3rd Party CAC enablers per https://militarycac.com/macuninstall.htm AND reenable the native smart card ability (very bottom of macuninstall link above)

If you purchased your Mac with OS Catalina (10.15.x) or Big Sur (11.xx.x) already installed, you can skip the uninstall part above and follow the instructions below.

6 'high level' steps needed, follow down the page to make this a painless systematic process

Step 1: Is your CAC reader Mac friendly?

Visit the USB Readers page to verify the CAC reader you have is Mac friendly.

Visit the USB-C Readers page to verify the CAC reader you have is Mac friendly.

'Some, not all' CAC readers may need to have a driver installed to make it work.

NOTE: Readers such as: SCR-331 & SCR-3500A may need a firmware update (NO OTHER Readers need firmware updates).

Information about these specific readers are in Step 2

Step 2: Can your Mac 'see' the reader?

Plug the CAC reader into an open USB port before proceeding, give it a few moments to install

Step 2a: Click the Apple Icon in the upper left corner of the desktop, select 'About This Mac'

Step 2b: Click 'System Report...' (button)

Step 2c: Verify the CAC reader shows in Hardware, USB, under USB Device Tree. Different readers will show differently, most readers have no problem in this step. See Step 2c1 for specific reader issues.

Step 2c1: Verify firmware version on your SCR-331, SCR-3310 v2.0, GSR-202, 202V, 203, or SCR-3500a reader. If you have a reader other than these 6, Proceed directly to step 3

Step 2c1a-SCR-331 reader

If your reader does not look like this, go to the next step.

In the 'Hardware' drop down, click 'USB.' On the right side of the screen under 'USB Device Tree' the window will display all hardware plugged into the USB ports on your Mac. Look for “SCRx31 USB Smart Card Reader.” If the Smart Card reader is present, look at 'Version' in the lower right corner of this box: If you have a number below 5.25, you need to update your firmware to 5.25. If you are already at 5.25, your reader is installed on your system, and no further hardware changes are required. You can now Quit System Profiler and continue to Step 3.

Step 2c1b-SCR-3310 v2.0 reader

If your reader does not look like this, go to the next step.

In the 'Hardware' drop down, click 'USB.' On the right side of the screen under 'USB Device Tree' the window will display all hardware plugged into the USB ports on your Mac. Look for “SCR3310 v2.0 USB Smart Card Reader.” If the Smart Card reader is present, look at 'Version' in the lower right corner of this box: If you have a number below 6.02, it will not read the 'G+D FIPS 201 SCE 7.0' CAC on Mac OS 11.xx.x or 10.15.7. I contacted HID (the company that makes these readers) on 14 DEC 2020 to find a way to update the firmware to 6.02. They said there is not firmware update for the reader. If your reader is older, you may need a new one. Please look at: https://militarycac.com/usbreaders.htm to find a compatible one. If you are already at version 6.02, your reader should work fine on your Mac and no further hardware changes are required. You can now Quit System Profiler and continue to Step 3.

Step 2c1c-SCR-3500A reader

If you have the SCR3500A P/N:905430-1 CAC reader,you may need to install this driver, as the one that installs automatically will not work on most Macs. Hold the control key [on your keyboard] when clicking the .pkg file [with your mouse], select [the word] Open

Step 3: Verify which version of MacOS you have?

(You need to know this information for step 6)

Step 3a: Click the Apple Icon in the upper left corner of your desktop and select 'About This Mac'

Step 3b: Look below Mac OS X for: Example: Version 10.X.X, or 11.X

Step 4: Figure out which CAC (ID Card) you have

(You need to know this information for step 6)

Look at the top back of your ID card for these card types. If you have any version other than the seven shown below, you need to visit an ID card office and have it replaced. All CACs [other than these six] were supposed to be replaced prior to 1 October 2012.

NOTE: If you are missing any of the above certificates, you have 2 choices,

1. Delete all of them, and re-run the 5 files above, or

2. Download the allcerts.zip file and install each of the certificates you are missing individually.

Errors:

Error 100001 Solution

Error 100013 Solution

You may notice some of the certificates will have a red circle with a white X . This means your computer does not trust those certificates

You need to manually trust the DoD Root CA 2, 3, 4, & 5 certificates

Double click each of the DoD Root CA certificates, select the triangle next to Trust, in the When using this certificate: select Always Trust, repeat until all 4 do not have the red circle with a white X.

You may be prompted to enter computer password when you close the window

Once you select Always Trust, your icon will have a light blue circle with a white + on it.

The 'bad certs' that have caused problems for Windows users may show up in the keychain access section on some Macs. These need to be deleted / moved to trash.

The DoD Root CA 2 & 3 you are removing has a light blue frame, leave the yellow frame version. The icons may or may not have a red circle with the white x

If you have tried accessing CAC enabled sites prior to following these instructions, please go through this page before proceeding

Clearing the keychain (opens a new page)

Please come back to this page to continue installation instructions.

How to create a Windows 10 bootable USB on macOS Catalina? If that question has been bothering you for a while, we've got a couple of great solutions. Just because ISO is not a native format for macOS computers, that doesn't mean there are no tools to get the job done on a Mac. In fact, we've showcased the best two methods to create Windows 10 bootable USB media on macOS Catalina, the latest version of the Mac operating system for iMacs, MacBook Pro and other desktop-based devices.

Advantages of Upgrading to macOS Catalina

The latest iteration of Apple's desktop software offers several advantages over previous versions like Mojave and High Sierra. Although macOS Catalina will forever be known as the iTunes killer, it did bring a whole new set of features apart from decimating the famous media manager and breaking it up into three parts. Here are some of the key advantages it brings to Mac users worldwide:

● The sidecar feature allows you to use an iPad in tandem with your Mac computer as a secondary screen. This creates a seamless transition between the touch and pen-enabled iPad and the keyboard and mouse-restricted Mac interface, allowing you a great deal of flexibility in the process.

● The Screen Time app makes it easy to manage how long your kids or even you use the computer, allowing you to manage computer and mobile addiction in a safe and convenient way.

● The Photos app now does a better job of curating the best images in your collection, and the integration of artificial intelligence elements makes it more intuitive when you're searching for specific memory moments.

macOS Catalina is also great for making Windows 10 bootable USB, as long as you have the right tools and know the right methods to get the task done. Here are the three best methods to create Windows 10 bootable USB on mac Catalina with detailed instructions.

Create Windows 10 Bootable USB on Mac Catalina #1:UUByte ISO Editor

Creating Windows 10 bootable USB on Mac Catalina is much more challenging than doing it with a Windows PC, which has many tools to complete the task. Actually, you can use Terminal app on Mac for this task but it involves complex commands and this is very hard for beginners. So our first recommendation is a beautiful GUI-based app called UUByte ISO Editor.

UUByte ISO Editor is a great tool to manage your ISO files on Mac, including the one to create Windows bootable USB for installation. In addition, you can edit ISOs, extract content, add or remove files, and even copy CDs to ISO. The interface is user-friendly, and you won't have to do all the complicated work of verifying your ISO after burning, messing around with complicated settings, and so on.

Highlights of ISO Editor

• Simplified and elegant user interface.
• Support large Windows 10 ISO file (> 5GB).
• Easily create Windows bootable USB and DVD.
• Edit ISO files and repack into a new one.
• Extract content from ISO image to local hard drive.
• Support latest macOS Catalina and Windows 10.

Step 1: Download and Install UUByte ISO Editor App on Mac Catalina

Download and Install UUByte ISO Editor for Mac. Make sure you download an authentic copy of the DMG file from the official website.

Step 2: Download Windows 10 ISO and Insert USB

Download the ISO file for Windows 10 from the official Microsoft website. Since you're on a Mac, you'll get to bypass the Media Creation Tool and download the ISO file directly to your computer. Insert your USB pen drive with at least 6 to 8GB of free space. If you have anything on it, take a backup because it will be formatted when creating the Windows 10 installer.

Step 3: Start Creating Windows 10 Bootable USB on Mac Catalina

In the UUByte interface, you'll see several modules, including Burn; click on it. On the next page, you'll see your USB drive automatically detected. Import the downloaded Windows 10 ISO to the app and hit the Burn button and wait for your Windows 10 bootable USB to be ready in less than 10 minutes.

[Edit]: Old version of UUByte ISO Editor is unable to handle latest Windows 10 ISO image and we fixed the issue. Please download the latest version of UUByte ISO Editor from our website and burn large Windows 10 ISO to USB. A new pop-up message will show up, telling you it is currently in process to split install.wim file contained in ISO image. Please wait 3- 10 minutes for that.

This is the easy way to create a Windows 10 bootable USB on Mac Catalina, but there's also another way if you're familiar with setting up a virtual machine on your Mac.

Create Windows 10 Bootable USB on Mac Catalina #2: Boot Camp Assistant

Boot Camp Assistant is pre-built app of macOS that essentially run Windows OS on a Mac. Fortunately, you can piggyback on it to get the Windows 10 ISO file and write it to a USB drive. Here are the steps you need to replicate to use Boot Camp Assistant app for creating Windows 10 bootable USB on Mac Catalina.

Step 1: Launch Boot Camp Assistant and then insert your USB drive into an available and working port. The will need to be of 6GB capacity for the 32-bit version and 8GB for the 64-bit version of ISO, depending on which one you downloaded.

Step 2: In Boot Camp, choose the option for creating an install disk. Be sure not to choose the Install option because you're not doing an installation right now, just creating the bootable media so you can install Windows 10 on a different machine.

Step 3: When you hit Continue, the software will automatically pick up the ISO file and display the location in the ISO Image section. Make sure it's the right one and also make sure that your USB is correctly displayed in the section below it.

Step 4: When you see the name of your USB drive change to WININSTALL in Finder, that means it's ready to be used as an installer. Eject it in Finder and remove it from your Mac.

This method is easy and doesn't require additional tools, but Boot Camp Assistant has known issues when working with Windows 10 ISO for that reason, we recommend UUByte ISO Editor for Mac since you won't have any of those problems. If you're technically adept, you can also try creating a virtual machine, as explained in the following section.

Cons:

• No enough disk error.
• Not recognizing USB drive .
• No USB option available .

Create Windows 10 Bootable USB on Mac Catalina #3: Virtual Machine

Virtual machine is now widely known to most of us, especially in tech field. The virtual machine software are able to run a guest operating system along side with the host operating system. It means you can run a Windows 10 instance on a Mac. This can be done with the help of VirtualBox software, a free and open source tool.

The process is a little complicated if you don't know what you're up against, so we're not covering it in this article. You can head over to the WikiBooks web page for that. Once you've done that, you will need to set up Windows 10 in VirtualBox to create the installer. Once you've done that using this resource, you can now use the media creation tool to get the ISO and create the Windows 10 USB installer. The process is explained below:

Step 1: Download VirtualBox Mac DMG file and create a new virtual machine in VirtualBox.

Step 2: In the Windows environment that you've set up on your Mac, open a browser window and head over to the Windows 10 ISO download page.

Step 3: Follow the process to download the ISO file. Make sure you choose the option to download the media creation tool and then to download the ISO file so you can use the tool to create the installer without any additional software.

Step 4: Insert a blank USB into Mac and use Media Creation Tool to download and burn the ISO file to the USB drive.

Cons:

Macos Catalina Bootcamp Not Working

• Complex setup for non-technicians.
• Operations in Virtual machine is limited.
• USB may not be recognized in Virtual machine.

Conclusion:

Bootcamp Windows 10 Macos Catalina

Obviously, this is a roundabout method to create Windows 10 bootable USB on Mac Catalina that you should only consider if you're comfortable with setting up the virtual machine in the first place. The better option is to use UUByte ISO Editor for Mac because you won't have to mess about with complex tasks. All you need is a USB drive, an authentic Windows 10 ISO, and the software itself. In just a few minutes after that, you'll have a reliable USB installer for Windows 10 that you can use any number of times to set up a PC running the latest version of Microsoft's operating system.
