Requirements to create a bootable installer.Why does one need to make a bootable USB on a Mac?.Don’t believe me? Follow along to create a bootable USB drive installer for macOS. While hearing the name may make you wonder if it’s anything complex, it is not as hard as you think. You're almost there.A bootable USB installer is something that contains the files to boot your Mac to any particular macOS version. You'll know when it's done because it will reappear on your desktop and tell you in the terminal window. Then wait for your bootable flash drive to be created. Change the N to whatever number your flash drive is assigned. Then copy and paste of=/dev/rdiskN into the terminal window.
It will paste the correct /path/to/downloaded.img for you, and even place the need space after. Then drag the Lubuntu iso image from the desktop onto the terminal window. Your flash drive will unmount and disappear from the desktop.Ĭopy and paste sudo dd if= into the terminal. Change the N to whatever number you found in the previous step. Note the number assigned to your flash drive.Ĭopy and paste diskutil unmountDisk /dev/diskN. ubuntu.dmg).Ĭopy and paste the commands from the web page to the terminal window.Ĭopy and paste diskutil list and hit return. Execute sudo dd if=/path/to/downloaded.img of=/dev/rdiskN bs=1m (replace /path/to/downloaded.img with the path where the image file is located for example. Run diskutil unmountDisk /dev/diskN (replace N with the disk number from the last command in the previous example, N would be 2)ĥ. Run diskutil list and determine the device node assigned to your flash media (e.g., /dev/disk2)Ĥ. Go down to the bottom of the page to "other procedure" and start with line #3.
That step is not needed and doesn't seem to work-as you have found out. If you go back and read my earlier post, I said to skip trying to convert the iso to an img (dmg) file. That would probably ruin your day.Īnd again, I don't know if this will work with the Ubuntu 10.10 iso. Just make sure to follow the directions closely so you don't accidently overwrite your hard drive. I use this method on an almost daily basis to test Lubuntu daily iso's. You can skip the part about changing the iso to a img first. On my MDD, it takes about 100 seconds to create the flash drive.
It's basically the same as the "Manual Approach" at the top of the page, but with one little change that speeds the whole process up greatly. Use the "Other Procedure" method at the bottom of the page. to install Ubuntu on MacBook using USB Stick I don't know if it will work for Ubuntu 10.10, though. I always use dd to create a bootable (Mac) flash drive for Lubuntu. Still, maybe I've misunderstood the original post. I've never used unetbootin, but the link provided says the resulting USB flash drive will only boot a PC, not a Mac.
