Just Purchased and some issues

Doctordun

First: I am using and iMac with latest operating system. I changed the name of the encrypted folder in my DropBox. The new name will not propagate to any other device and not even the web location of DropBox. Do I have to create a new encrypted folder with the name I want?
Second: On my primary computer, the Security window with "Enable Filename Encryption" is dim. On other devices it it not dim and I can select it. What do I do?

If the filename change isn't synced to other devices or to the cloud, then the Dropbox sync engine isn't running on your Mac. Please check.
Regarding the second question: if the option is greyed-out, then the option isn't available, that means, you are signed in with a FREE version - maybe you have multiple accounts (licensed and not).

Best,
