These advanced steps are primarily for system administrators and others who are familiar with the command line. You don't need a bootable installer to upgrade macOS or reinstall macOS, but it can be useful when you want to install on multiple computers without downloading the installer each time.
To directly burn video files to ISO image file for USB drive, you could insert your USB drive into the computer and then try to choose it as target in the “Save to” box. If it can’t be chosen as target, choose another directory and copy and paste the created ISO file to USB drive after burning. Notes on ISO Support: All versions of Rufus since v1.1.0 allow the creation of a bootable USB from an ISO image (.iso). Creating an ISO image from a physical disc or from a set of files is very easy to do however, through the use of a CD burning application, such as the freely available CDBurnerXP or ImgBurn. Frequently Asked Questions (FAQ). Jun 05, 2015 If you have downloaded an ISO image of another operating system, say Ubuntu Linux or Windows 10, and you wish to turn that ISO image file into a bootable USB installer drive using a USB flash drive or USB key, you’ll find the most reliable way to copy or ‘burn’ the ISO to that target USB volume is by turning to the command line of Mac OS X.
Jun 22, 2011 How to install from USB Stick rather than CDROM Am using a USB Stick to install Ubuntu Server 11 on a Linux machine, rather than using CD-ROM. (Am using Mac OSX 10.6.7 to download my iso, configure USB stick, and then copy.iso to it) This worked for me - Insert 4GB USB Stick - Open Disk Utility, Click ERASE. Format USB using MS-DOS (FAT). Mar 11, 2020 Unfortunately, it's not that simple. Properly burning an ISO to USB is different than just copying the file.It's even different than burning an ISO to a disc.Adding to the complexity is that you plan on booting from the USB drive once you're done getting the ISO image on there. (Am using Mac OSX 10.6.7 to download my iso, configure USB stick, and then copy.iso to it) This worked for me - Insert 4GB USB Stick - Open Disk Utility, Click ERASE. Format USB using MS-DOS (FAT) - When Disk appears in Left hand column, right click and get Information (note down the 'Disk Identifier: eg disk6'). Mar 30, 2020 Part 1. Top 12 Free DVD ISO Burner to Burn ISO Free on Windows/Mac there're several helpful free ISO burners available on the internet which allow users to burn the ISO files to DVD discs without any charge. In this part, we're going to introduce 12 most helpful free ISO burning software to help you with the task.
Find the appropriate download link in the upgrade instructions for each macOS version:
macOS Catalina, macOS Mojave, ormacOS High Sierra
Installers for each of these macOS versions download directly to your Applications folder as an app named Install macOS Catalina, Install macOS Mojave, or Install macOS High Sierra. If the installer opens after downloading, quit it without continuing installation. Important: To get the correct installer, download from a Mac that is using macOS Sierra 10.12.5 or later, or El Capitan 10.11.6. Enterprise administrators, please download from Apple, not a locally hosted software-update server.
OS X El Capitan
El Capitan downloads as a disk image. On a Mac that is compatible with El Capitan, open the disk image and run the installer within, named InstallMacOSX.pkg. It installs an app named Install OS X El Capitan into your Applications folder. You will create the bootable installer from this app, not from the disk image or .pkg installer.
MyVolume
in these commands with the name of your volume.Y
to confirm that you want to erase the volume, then press Return. Terminal shows the progress as the bootable installer is created. * If your Mac is using macOS Sierra or earlier, include the --applicationpath
argument, similar to the way this argument is used in the command for El Capitan.
After creating the bootable installer, follow these steps to use it:
For more information about the createinstallmedia
command and the arguments that you can use with it, make sure that the macOS installer is in your Applications folder, then enter this path in Terminal:

Most new PCs don't come with DVD drives anymore. So it can be a pain to install Windows on a new computer.
Luckily, Microsoft makes a tool that you can use to install Windows from a USB storage drive (or 'thumbdrive' as they are often called).
But what if you don't have a second PC for setting up that USB storage drive in the first place?
In this tutorial we'll show you how you can set this up from a Mac.
You can download the ISO file straight from Windows. That's right - everything we're going to do here is 100% legal and sanctioned by Microsoft.
If you want an English-language version of the latest update of Windows 10, you can download the ISO here.
If you have a relatively new computer, you probably want the 64-bit version. If you're not sure, go with the 32-bit version to be safe.
If you want a non-English-language version of Windows, or want to get an older update version, download the ISO here instead.
The ISO file is only about 5 gigabytes, but I recommend you use a USB drive with at least 16 gigabytes of space just in case Windows needs more space during the installation process.
I bought a 32 gigabyte USB drive at Walmart for only $3, so this shouldn't be very expensive.
Stick your USB drive into your Mac. Then open your terminal. You can do this using MacOS Spotlight by pressing both the ⌘ and Space bar at the same time, then typing 'terminal' and hitting enter.
Don't be intimidated by the command line interface. I'm going to tell you exactly which commands to enter.
Open Mac Spotlight using the ⌘ + space keyboard shortcut. Then type the word 'terminal' and select Terminal from the dropdown list.
Paste the following command into your terminal and hit enter:
diskutil list
You will see output like this (note - your Mac's terminal may be black text on a white background if you haven't customized it).
Copy the text I point to here. It will probably be something like
/dev/disk2
.
Next format your USB drive to Windows FAT32 format. This is a format that Windows 10 will recognize.
Note that you should replace the disk2
with the name of the your drive from step 3 if it wasn't disk2
. (It may be disk3
or disk4
).
Run this command using the correct disk number for your USB:
diskutil eraseDisk MS-DOS 'WIN10' GPT /dev/disk2
Then you'll see terminal output like this.
This will probably only take about 20 seconds on a newer computer, but may take longer on an older computer.
Note that for some hardware, you may instead need to run this command, which uses the MBR format for partitioning instead of GPT. Come back and try this command if step 7 fails, then redo steps 5, 6, and 7:
Now we're going to prep our downloaded ISO file so we can copy it over to our USB drive.
You will need to check where your downloaded Windows 10 ISO file is and use that. But your file is probably located in your ~/Downloads
folder with a name of Win10_1903_V1_English_x64.iso
.
hdiutil mount ~/Downloads/Win10_1903_V1_English_x64.iso
Update April 2020: One of the files in the Windows 10 ISO – install.wim – is now too large to copy over to a FAT-32 formatted USB drive. So I'll show you how to copy it over separately.
Thank you to @alexlubbock for coming up with this workaround.
First run this command to copy over everything but that file:
rsync -vha --exclude=sources/install.wim /Volumes/CCCOMA_X64FRE_EN-US_DV9/ /Volumes/WIN10
Then run this command to install Homebrew (if you don't have it installed on your Mac yet):
/usr/bin/ruby -e '$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)'
Then use Homebrew to install a tool called wimlib with this terminal command:
brew install wimlib
Then go ahead and create the directory that you're going to write the files into:
mkdir /Volumes/WIN10/sources
Then run this command. It will use wimlib to split the install.wim file into 2 files less than 4 GB each, then copy them over to your USB:
wimlib-imagex split /Volumes/CCCOMA_X64FRE_EN-US_DV9/sources/install.wim /Volumes/WIN10/sources/install.swm 4000
Once that's done, you can eject your USB from your Mac inside Finder.
Congratulations - your computer now should boot directly from your USB drive. If it doesn't, you may need to check your new PC's BIOS and change the boot order to boot from your USB drive.
Windows will pop up a screen and start the installation process.
Enjoy your new PC, and your newly-installed copy of Windows.
