I'm trying to turn on FileVault on my computer, but I keep getting a window that says I can't use FileVault on my computer or with my operating system. I have a 2009 Mac Pro with 3.33 6-core processors (5,1) and I'm running the last version of Mojave, macOS X 14.6 with updates. I smell a conspiracy by Apple to render my Mac Pro obsolete so I will be forced to buy a new computer. Just kidding...or am I?
Mac Pro 2009 is not supported on Mojave, per Apple.
Mac Pro 2010 and 2012 with Metal graphics are the oldest, per:

How are you trying to enable FileVault, and what is the exact text of the error message?

Mr. Hoffman:
I have a 2009 Mac Pro with 2010 processor upgrades. Although there are limitations, the computer calls itself a 5,1 version. The 3.33 six-core processors are a 2010 version (5,1), not 2009 (4,1). So, as far as I know (and my computer tells me this on the About This Mac pane), I am running Mojave 14.6 with security updates, the last version before Catalina.
Now, I am trying to enable FileVault through the Security and Privacy Preferences. I didn't know there was another way. I enter my password, unlock the lock, and click on the button that says Turn On FileVault. Then, I get a drop-down pane that says "FileVault cannot be used on this system and operating version," without any further explanation.
Again, Mac Pro 2009 is not supported on Mojave.
You’re likely going to have to dig, as the details and potential side effects of this hardware conversion are unclear.
Install High Sierra as a test, and install a clean copy of Mojave as a test, and see if that works better.
I will try what you advised.
