Hi, guys, I recently encountered a problem. I have an old MacBook Air, and the system has become slow. Someone told me I could install Ubuntu to improve performance, but I don’t know how. Can I burn an ISO to a USB and boot from the USB to install Ubuntu? How do I burn an ISO to a USB flash drive?

Of course, you can! It is perfectly feasible to burn ISO files to USB on a Mac. Whether you want to install an operating system, create a Windows 10 bootable USB , or use certain recovery tools, Mac provides built-in tools and methods to help you with this task. As long as the USB has enough space and the ISO file is valid, you can successfully burn the ISO file through the Mac.

If you want to burn from ISO to USB on your Mac without third-party software, you can choose to use Terminal.

  1. Download the ISO file, and connect the USB drive to your Mac.
  2. To burn an ISO to a USB flash drive, you should back up the USB drive, as the data on the USB will be erased during the burning process.
  3. Open Terminal on your Mac.
  4. Enter the diskutil list command in the Terminal. This command will list all the drives. The name of the USB flash drive should be /dev/disk0, /dev/disk1, and /dev/disk2.
  5. Use the following command to unmount your USB drive (replace disk1 with your actual USB disk identifier): diskutil unmountDisk /dev/disk1
  6. Use the dd command to burn the ISO to your USB. Make sure to replace /path/to/your.iso with the full path to your ISO file, and replace disk2 with your USB’s disk identifier: sudo dd if =/path/to/your.iso of=/dev/rdisk2 bs=1m
  7. Once the process is complete (it might take a while), eject the USB drive using the following command: diskutil eject /dev/disk2
