I have an external USB drive and want to encrypt it. I have seen many 'suggestions' on how to do that, but I do not see any option to encrypt the drive. I am using MacOS 10.13.2.
I have see, for example, this answer. But in step 9, when I right click the drive (on the Desktop or the Finder), there is no option 'encrypt'. Before that I have formatted the drive in the 'Mac OC Extended (Journaled)' format. No option for encryption in the
Disk Utility either ...
So how to do that? Maybe the option was forgotten in the new OS version?
