I am using the latest MacOS High Sierra, and there is a bug in VeraCrypt's Mac version.

Two parts to this bug, so really it's two 'bugs':

  1. A 50GB hidden volume .tc file created by either MacOS VC or Windows VC (with an exFAT 49GB hidden volume inside a 50GB total .tc file), does not successfully mount in MacOS VeraCrypt (either 1.21 or 1.22 BETA 4), UNLESS you untick 'TrueCrypt Mode' upon decrypting.

It gives the following error:

"Operation failed due to one or more of the following:

  • Incorrect password.
  • Incorrect Volume PIM number.
  • Incorrect PRF (hash).
  • Not a valid volume."

In Windows, am I right in observing that TrueCrypt Mode is unticked by default? If so, should the mac version be updated similarly to fix this bug too?

  1. Even if you untick 'TrueCrypt Mode', the hidden volume does not launch properly (at least GUI-wise) like VeraCrypt volumes normally do as a mounted disk in MacOS's Finder application. It does mount - to /Volumes/Untitled - but you have to manually navigate to that folder in Finder, and it's tricky to do so for non-advanced users. I was pulling my hair out until I noticed the VeraCrypt app does show the path of the mounted volume after all. But this bug makes it look like mounting just fails and is hard for not so savvy users to even know it works.

Hope it's easy to fix this bug!

Just a note to dev: MacOS spies on users far less than Windows 10 so it is a good OS to support for those not using Linux!

Thank you for your work on the important VeraCrypt.
