Q: filevault continues coding without interruption and macbook air does not make me turn off filevault

Hi fgpf,

I apologize, I'm a bit unclear on exactly what you are describing or asking. If you are trying to turn off FileVault, you may find the following articles helpful; otherwise, you may need to clarify a bit what is going on or what you are trying to do:
