So I have a keyboard / mouse issue; neither built-in will work..

To troubleshoot that, I'd like to make changes and restart a couple times.

One thing I tried was disable FileVault manually from system preferences and now I kind of regret it since it now tells me "more than a day" until finished. My google search shows I can't cancel and now have to wait for it to finish...

I read online that when encrypting, you can continue using your laptop like nothing is happening and this makes me wonder if the reverse is true as well.

Can I shut down my laptop without messing up the decryption process & corrupt my SSD or my data?

  • Could you please clarify what kind of Mac and version of macOS you are using? Does this issue happen only with the built-in trackpad and keyboard, or does this occur with external wired or wireless mice or keyboards? – drivec Mar 22 '18 at 19:45

You can safely use, shutdown, sleep, and restart your Mac during the FileVault encryption and decryption process. The process happens in the background while your Mac is awake and plugged in.

FileVault encryption or decryption can take hours or days to complete, depending on your disk size and type. You simply have to be patient and let it finish. Portable Macs are required to be plugged in to decrypt or encrypt, so keep it plugged in and on if you want it to complete in a timely manner.

Your encryption or decryption will pause when asleep, shut down, or unplugged, and it will resume when awake and plugged in.

See the following for more information:

The question about your mouse and keyboard issue is, at the time of writing, very unclear and may be better suited for another separate question. It's highly unlikely that FileVault will have an impact on your built-in keyboard or trackpad.

  • where did you read this? Is there an Apple support link for this ? – cameronroe Jan 11 at 9:42
  • @cameronroe I've done a quick bit of Googling and added some links to my answer. – drivec Jan 11 at 22:03
