Does FileVault slow down Macs?

Episode 1470 (41:50)

Laurie from Santa Monica, CA
FileVault

Laurie has been having shut down issues on her MacBook Pro and has been told by an Apple Genius that it's because of FileVault being turned on. Is that causing problems? Leo says absolutely not. That doesn't impact the Mac at all. There's no hit to performance either. FileVault is a good idea because it will keep her data encrypted in case her laptop gets stolen. Leo says what's more likely the case is that her battery is bad and that Apple will replace it.
