iPhone locked notes cracking

[Lincolnshire]

I used this C:\Users\Tom\john-1.9.0-jumbo-1-win64\run>john.exe C:\Users\Tom\SQLite\hash.txt --format=notes-opencl

And it returned saying No OpenCL devices found.

Do I do a wordlist like in a notepad and save it in the same folder as hash.txt?

I am a noob - I have no idea how to use a hashcat rules attack.
