I am using a macbook pro with filevault turned on. I am planning to start using a zero-knowledge cloud service (sync.com) for all my files, to have a secure backup and as a way to share certain files with others. I was wondering if the two types of encryption will work alongside each other. If so, where in the process does the cloud encryption engage, and where does filevault take over? Will there be unnecessary redundancy in the two encryptions (perhaps with longer waiting times)?
Just trying to picture what will happen. Thanks!

On macOS, FileVault is encryption at rest so it’s designed to protect your files when the operating system isn’t operating. Just as you can see an email or text document once you log in and your password decrypts the drive, any apps can read clear versions of your files and send them to the cloud in the clear, print them in the clear.
Having FileVault doesn’t make things slower or faster, so you can pretty much exclude that from your worries and plans about whatever cloud sharing service and program you select.
That service will be fast or slow, secure or not on its own design and merits regardless of the status of FileVault.
