Creating install media on macOS Big Sur

Lucas Holt edited this page Aug 21, 2022 · 1 revision

Download a MidnightBSD install media file from the FTP or website. These files end in img.

On your Mac, open terminal

Run the command: diskutil list

You should have a new drive listed, usually at the bottom. Look at the disk number. You'll see something like /dev/disk4

If your USB flash drive had a file system macOS understands like FAT32 or HFS+, you may need to unmount the disk. Use the following command, but be sure to update the disk number if needed.

diskutil unmountDisk /dev/disk4

Now go into the folder where you have your MidnightBSD image, often in the ~/Downloads folder.

Say it's Downloads cd ~/Downloads

Then run the following. Replace the input to if= with the name of your download image. Replace the disk number if needed. sudo dd if=MidnightBSD-2.0.6.img of=/dev/rdisk4 bs=1m

Once it's done, just remove the flash drive from your USB port and stick it in your computer you wish to install MidnightBSD on.
