If you want to ensure full Mac compatibility on your USB drive or flash disk, follow the easy steps below. The only way to be sure of the content you are formatting is to first remove the USB drive from Mac, know the title of other storage disks, insert the USB disk again and note the name of the disk. Now you are sure not to be formatting a wrong disk this way. Then you are set to get it done! As earlier stated, you need to first back up your USB drive before formatting the drive as you may not be able to recover the contents again.

I am no expert but you could do the same with mavericks in your ssd and upgrade from there.

Hi, Charles. Hi Charles.

Did the tech support team help you? It happened to me also disk not seen in Diskutil list on the terminal … but I rebooted the mac again and start from the beginning and then it showed up in Disk Utility it was not the first time. But just reboot and after a few time it should detect it. I am sorry to hear about the issues Guilherme.

here If the issue persists and you bought the drive from us please contact our support team. This article really helped! At that point I knew from your article that formatting the drive and restoring from a TimeMachine backup would be fairly easy. Or will it not give you an option of installing High Sierra?

If the computer was not upgraded to High Sierra before hand the internet recovery will be for an older OS. Is it at all possible to upgrade to high sierra if you were not already upgraded to it before installing the new SSD? B If the SSD is not showing up Terminal sould be used to format the drive, which is outlined in the remaining steps.
