Thanks for your reply Chris, The software used to create the media was rufus 3.17, following this tutorial: https://ubuntu.com/tutorials/create-a-usb-stick-on-windows
The media boots without error from within a virtual machine via plopboot and plopkexec, but not on bare metal of the same hardware, and successfully boots on a Lenovo Thinkcentre M700. I'm not sure why the media is failing to boot only on bare metal for the Macbook. If there are any other validation steps I can take I would be glad to do so. The issue has been posted on ask ubuntu and the suggestions so far have been to validate the media: https://askubuntu.com/questions/1383225/how- to-boot-from-a-live-usb-stick-on-a-mac I look forward to hearing from you. Kind regards, Scott. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1955611 Title: Unable to boot Live USB on Mac To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/casper/+bug/1955611/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
