+<strong>I'm encountering an "Operation not permitted" error with VeraCrypt on macOS when trying to mount a file container. How can I resolve this?</strong></div>

+

+<p>This specific error, which appears in the form "Operation not permitted: /var/folders/w6/d2xssyzx.../T/.veracrypt_aux_mnt1/control VeraCrypt::File::Open:232", has been reported by some users. It is the result of macOS not granting the necessary permissions to VeraCrypt. Here are a couple of solutions you can try:</p>

+

+<ul>

+<li>A. Granting Full Disk Access to VeraCrypt:

+<p>

+<ol>

+ <li>Go to <code>Apple Menu</code> > <code>System Settings</code>.</li>

+ <li>Click on the <code>Privacy & Security</code> tab.</li>

+ <li>Scroll down and select <code>Full Disk Access</code>.</li>

+ <li>Click the <code>+</code> button, navigate to your Applications folder, select <code>VeraCrypt</code>, and click <code>Open</code>.</li>

+ <li>Ensure that the checkbox next to VeraCrypt is ticked.</li>

+ <li>Close the System Settings window and try using VeraCrypt again.</li>

+</p>

+</ol>

+</li>

+<li>B. Using the sudo approach to launch VeraCrypt:

+<p>You can launch VeraCrypt from the Terminal using elevated permissions:

+

+<pre>

+sudo /Applications/VeraCrypt.app/Contents/MacOS/VeraCrypt

+</pre>

+

+Running VeraCrypt with sudo often bypasses certain permission-related issues, but it's always a good practice to grant the necessary permissions via the system settings whenever possible.</p>

+Starting from Windows 10 version 1903 and later, Microsoft introduced a feature called <b>Windows Sandbox</b>. This is an isolated environment designed to run untrusted applications safely. As part of this feature, Windows generates a dynamic virtual hard disk (VHDX) which represents a clean Windows installation. This VHDX contains a base system image, user data, and the runtime state, and its size can vary depending on system configurations and usage.

+</p>

+<p>

+When VeraCrypt enumerates devices on a system, it identifies all available disk devices using device path formats like <b>\Device\HardDiskX\PartitionY</b>. VeraCrypt lists these devices, including virtual ones such as those associated with Windows Sandbox, without making distinctions based on their physical or virtual nature. Therefore, you might observe an unexpected device in VeraCrypt, even if it doesn't appear as a physical disk in tools like diskpart.
