Ask HN: Install macOS in another partition and boot it before crossing borders?

3 pointszuck92 comments

This is in response to the recent Basecamp handbook and 1Password's new feature.

How technically competent are the folks who search devices at borders? What if I install macOS in another partition, boot it up, and unmount the original partition? Will they discover my data?

I realize nothing novel can be done in iOS devices without jailbreaking.

It sounds like you want some type of plausible deniability[1] or a way to hide your secure data in pain sight but often security through obscurity is a terrible idea.

Beyond using FileVault and a firmware password I don't think there's much else you can do besides physically removing the disk. Unfortunately that is not a easy task on the latest MacBooks.

Assume worst case.
