2 What is the Best Format to Choose When Formatting USB Drive on Mac
You'll be given several format options when you try to format a USB drive on Mac, including OS X Extended (Journaled), OS X Extended (Case-sensitive, Journaled), MS-DOS (FAT) and ExFAT. If you are using macOS 10.13 or later, you'll also see an option named APFS, which is the default file system of macOS 10.13 and later.
1APFS
APFS is a new file system for macOS. It's the most appropriate format for flash drives and SSDs. However, in order to write to this file system, you need to have the latest macOS. If you're sure that you won't connect the USB drive to a Mac computer running old version, then you can format your USB drive with APFS.
2OS X Extended (Journaled) & OS X Extended (Case-sensitive, Journaled)
This is the default file system for macOS 10.12 and earlier. It doesn't put a limit on the size of files you can save on the drive, and that's the greatest advantage. Windows-running computers can read the files formatted to OS X Extended (Journaled), but can't write to them. In other words, you can transfer files from Macs to PCs without any problem, but you won't be able to transfer files from PCs to Macs. If you need to transfer data between PCs and Macs, you should consider other options.
The biggest difference between OS X Extended (Journaled) and OS X Extended (Case-sensitive, Journaled) is the latter is case-sensitive to folder names. Therefore, if you do not have special needs, you can ignore this option.
3MS-DOS (FAT)
This is Disk Utility's name for FAT32 file system. It's compatible with Windows operating systems and macOS. A USB drive formatted this way can easily transfer data between PCs and Macs. However, a USB drive formatted to FAT32 doesn't support an individual file larger than 4GB.
4ExFAT
ExFAT, the successor of FAT32, offers larger storage space and supports files larger than 4GB. So, if you need to transfer large files between PCs and Macs, ExFAT will be the best format for your USB drive.

Looking for the best ISO to USB burner for Mac? It's possible, but ISO is not native file type in Mac OS X or macOS environment, so you need to use workaround methods or employ a third-party ISO burning utility for Mac to get this done. This article covers three ways to burn ISO to USB stick on a Mac computer, powered by macOS Catalina, Mojave, High Serria and earier Mac OS X systems.
The first thing you need to know is that you can't use an ISO disk image file on a Mac, since Apple primarily uses the DMG format. However, if you merely want to burn ISO to a USB stick, that's definitely possible. The only thing you can't do is run an ISO file on an Apple computer. Let's look at the various ways to burn ISO to USB on a Mac machine.
Notice: There are different types of ISO images (Windows, Linux, Raspbian OS, etc.) and they apply different booting schemes. So basically, there is not a perfect software out there that can burn all ISO images successfully. You should try another suggestion if one failed.
Updates: If you have any question during ISO burning process, please check out the FAQ Part at the end of this article.
Part 1: How to Burn ISO to USB on Mac with Terminal Software
Terminal is Apple's command line equivalent of Command Prompt in Windows and Terminal in Linux. Using this command line utility, you can burn an ISO file to an external DVD or USB disk. If you did not t have any experience with text command, then this is not recommended because it is too risky to damage the local disk with wrong input. Terminal allows you to do several system-level operations, so don't input anything other than the commands specified in the process outline shown below:
Step 1: Click Terminal icon from the Dock. Or Go to the Applications folder on Mac and find the Terminal app in Utilities folder.
Step 2: Copy the ISO file in a convenient location so your command doesn't have to be too long. Saving it to desktop or downloads folder is usually a good idea. Make sure you remember the name of the ISO file because it will be used in the command.
Step 3: If your ISO file is in your Desktop, then run the following command (press Enter after typing the command): cd desktop
Step 4: Now run the following command (hit Enter after typing): hdiutil burn filename.iso
Step 5: Once you run the command, your ISO file will be burned to the USB drive in your default optical drive. If you haven't inserted a disk, you will be prompted to do so. There is no need to run the command again after inserting the USB.
Cons:
- Dangerous and not safe for beginners.
- Sharp learning curve.
- Bad support for USB 2.0 device.
- Lower success rate.
If you want to avoid any kind of command line work and if you're running one of the newer versions of macOS, then it's better to use a third-party software like the one described in Part 2 below.

Part 4: Frequently Asked Questions
Q: Why file copying process failed?
The USB will be formatted to FAT32 in order to create a working Windows partition on Mac. This means you can not copy a file larger than 4GB. This is one of the biggest issue with FAT32 file system. We noticed that the latest Windows 10 ISO downloaded from Microsoft.com will over 5GB and the install.wim file is obviously larger than 4GB. That's why file copying process faile during burning process. The solution is to download an old version of Windows 10 from other sources.
Q: Why my USB drive is not bootable by using hdiutil command?
It is a common case for Windows ISO image because this command does not write Windows bootloader to USB drive. You have to format the drive to FAT32 first in Disk Utility.
Q: Can not select USB drive in UUByte ISO Editor?
If the USB drive could be recognized by Mac but not in UUByte ISO Editor, then it is highly possible that your Mac is in Dark Mode. To fix this, please switch to Light mode instead.

No. Mac can only see USB drive formatted with exFAT or MS-FAT. NTFS is not supported by Mac in default. So you can not write ISO image to NTFS USB on Mac. FAT32 is more recommended!

For high-speed USB drive (3.0 or 3.1), it can be done within 10 minutes. For low-speed USB drive, it takes much longers (more than 20 minutes).
