Yumi Boot Usb For Mac

To actually boot the drive, reboot your Mac and hold down the Option key while it boots. You’ll see the boot options menu appear. Select the connected USB drive. The Mac will boot the Linux system from the connected USB drive. If your Mac just boots to the login screen and you don’t see the boot options menu, reboot your Mac again and hold. I used YUMI to put the iBoot iso image onto the USB, which worked no problem. However when i boot from it, it boots straight into my current OS on that machine (Ubuntu). Seems to me that my Vaio is very picky about what it wants to boot. USB drive is top of the boot order and HDD is the very last option. Would the first method be. YUMI is a safe and free software that replaces optical drives by formatting items onto portable USB devices. This lightweight app has the capability to store multiple operating systems and platforms onto a single flash drive. While it's specifically designed for Linux systems, it. So if that sounds interesting, follow the guide below to create multiple bootable ISO files with YUMI. Steps to use YUMI to create multiboot USB. Download YUMI Multiboot USB creator. There are two versions of YUMI to download — the legacy YUMI tool and YUMI UEFI. It’s worth noting that the UEFI version uses GRUB2 for both UEFI and BIOS booting. Step 1) Download YUMI, guiformat, and Multibootusb from the links provided above. Step 2) Plug your USB into your computer and use guiformat to format the drive into the FAT32 file system, if it isn’t already. Step 3) Gather all the.ISO’s you want to burn to the USB. Step 5) This part is a bit harder.

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.

What you need to create a bootable installer

  • A USB flash drive or other secondary volume formatted as Mac OS Extended, with at least 14GB of available storage
  • A downloaded installer for macOS Big Sur, Catalina, Mojave, High Sierra, or El Capitan

Download macOS

Yumi Boot Usb For Mac Download

  • Download: macOS Big Sur, macOS Catalina, macOS Mojave, or macOS High Sierra
    These download to your Applications folder as an app named Install macOS [version name]. If the installer opens after downloading, quit it without continuing installation. 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.
  • Download: OS X El Capitan
    This downloads as a disk image named InstallMacOSX.dmg. 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.

Use the 'createinstallmedia' command in Terminal

  1. Connect the USB flash drive or other volume that you're using for the bootable installer.
  2. Open Terminal, which is in the Utilities folder of your Applications folder.
  3. Type or paste one of the following commands in Terminal. These assume that the installer is in your Applications folder, and MyVolume is the name of the USB flash drive or other volume you're using. If it has a different name, replace MyVolume in these commands with the name of your volume.

* If your Mac is using macOS Sierra or earlier, include the --applicationpath argument and installer path, similar to the way this is done in the command for El Capitan.


After typing the command:

  1. Press Return to enter the command.
  2. When prompted, type your administrator password and press Return again. Terminal doesn't show any characters as you type your password.
  3. When prompted, type Y to confirm that you want to erase the volume, then press Return. Terminal shows the progress as the volume is erased.
  4. After the volume is erased, you may see an alert that Terminal would like to access files on a removable volume. Click OK to allow the copy to proceed.
  5. When Terminal says that it's done, the volume will have the same name as the installer you downloaded, such as Install macOS Big Sur. You can now quit Terminal and eject the volume.
