[QUOTE="chscag, post: 1792186, member: 46727"] Not entirely true. Only internal SSD drives that have had macOS High Sierra installed will be formatted as APFS. That does not apply to external SSDs. And we really do not know if the Fantom is a SSD or a HHD? It appears from your screen shot that the Fantom HD is showing up as a boot selection. Did you click the small lock, enter your admin password and then select the drive to boot from? [/QUOTE]
