When I tried to inject the image, Transmac told me that the drive was "write protected". DISKPART> create partition primaryNote: I use "Rufus" for all other USB writing and formatting for Windows systems, it's a great app, but I had previously tried to format the drive as GPT using that, as a Fat32 partition. DISKPART> convert gptDiskPart successfully converted the selected disk to GPT format. DISKPART> cleanDiskPart succeeded in cleaning the disk. I've been trying to post this to confirm that it works for some time, I just hope it helps someone else, because it is a very easy solution.Now that you have all the necessary ingredients, youre ready to make a Mac OS X bootable USB using the DMG file of the operating system with the steps.Here are the Diskpart commands used to prep the Flash Drive, just to have them here in case my Link does not work: diskpart(Find the disk number) DISKPART> select disk x (from result of List Disk)Disk x is now the selected disk. Someone had reported that the method for using DISKPART did not work, but I have done this twice and it works remarkably well, and it's the only method I could find to create a Mac-Bootable Flash.(Is possible that you won't need the sudo at the begin, in that case just remove it from the command and start from "defaults")Now you should be able to install macOS from a USB drive.Just a little thing, make sure to have formatted the disk before proceeding, I would recommend to make a partition that takes the whole disk in mac Journaled format, then if you want you will be able to encrypt the disk (the installer will ask you to do that later), instead, if the disk was encrypted before, you will have to insert the encryption key of the disk to continue the installation process.Really hope this help, I spent a lot of hours to do this on a really old iMac from 2008. Then try to install the system, if this does not work again, you can start the installation without verifying the image, but you should really trust the image you're using from being corrupted or modified (just to make sure the download went right, use the SHA-1 code to make the file has been downloaded right).So, to proceed without verifying the image, from terminal, type in this command: sudo defaults write com.apple.frameworks.diskimages skip-verify trueThen, start the installation.
