Spent the whole day trying to get a bootable external SSD or USB to load UBUNTU on...

Hi everyone,

I’ve been trying to create a bootable USB drive for Ubuntu on my MacBook Pro 14" with an M3 chip running macOS Sonoma 14.4, but I’m encountering persistent issues. Here’s what I’ve tried so far:

1. Formatted USB as FAT32 with MBR:
   sh
   Copy code
   sudo diskutil eraseDisk FAT32 "LINUX" MBRFormat /dev/disk6
2. Converted ISO to DMG and wrote it to USB:
   sh
   Copy code
   hdiutil convert /Users/edwingoodridge/Downloads/ubuntu-24.04-desktop-amd64.iso -format UDRW -o /Users/edwingoodridge/Downloads/ubuntu-24.04-desktop-amd64.dmg
   mv /Users/edwingoodridge/Downloads/ubuntu-24.04-desktop-amd64.dmg /Users/edwingoodridge/Downloads/ubuntu-24.04-desktop-amd64.img
   sudo diskutil unmountDisk /dev/disk6
   sudo dd if=/Users/edwingoodridge/Downloads/ubuntu-24.04-desktop-amd64.img of=/dev/rdisk6 bs=1m status=progress
   sync
   sudo diskutil eject /dev/disk6
3. Attempted to Boot from USB:
   • Held down the Option key during startup, but the USB drive does not appear in the Startup Manager.

Additional Details:

• USB drive is identified as /dev/disk6.
• Verified USB drive contents, but failed to mount:
  sh
  Copy code
  sudo diskutil mount /dev/disk6

I’ve also tried using balenaEtcher and adjusting security settings to allow booting from external media, but no luck. Any insights or suggestions would be greatly appreciated.

Thank you!

Ubuntu ARM doesn’t support Apple Silicon unless you run it within a virtual machine like UTM, Parallels, or VMWare Fusion. To run native, you need Ubuntu Asahi

You don’t need an external boot device to install within a VM. Those programs will use the DMG.
