Fixing Vault Unlock Issues on macOS Due to MacFuse Hang on Cryptomator

Cryptomator is a popular open-source encryption software that allows users to secure their files and folders by creating encrypted vaults. However, like any software, Cryptomator may encounter occasional issues. One common problem on macOS is the inability to unlock a vault due to MacFuse hang. In this article, we will guide you through the process of reloading the MacFuse kernel extension to resolve this issue and regain access to your encrypted vault.

Step 1: Identify the Issue

Before proceeding with the fix, it’s essential to confirm that the problem you’re experiencing is indeed related to MacFuse hang. If you encounter an error or Cryptomator becomes unresponsive while attempting to unlock a vault, it may indicate a MacFuse issue.

Step 2: Open Terminal

To execute the necessary commands, you’ll need to use the Terminal application on your macOS system. You can find it in the “Applications” folder under the “Utilities” subfolder. Alternatively, you can use Spotlight (Cmd + Space) and search for “Terminal.”

Step 3: Unload the MacFuse Kernel Extension

In the Terminal window, enter the following command and press Enter:

sudo kextunload -b io.macfuse.filesystems.macfuse

You will be prompted to enter your administrator password. Type it in and press Enter. Note that when entering your password, no characters will be displayed on the screen, but the input is being registered.

Step 4: Wait for Unloading Process

Once you’ve entered the password, the system will start unloading the MacFuse kernel extension. This may take a few moments. Be patient and allow the process to complete.

Step 5: Reload the MacFuse Kernel Extension

After the unloading process finishes, it’s time to reload the MacFuse kernel extension. Enter the following command in the Terminal window and press Enter:

sudo kextload -b io.macfuse.filesystems.macfuse

Again, you’ll be prompted to enter your administrator password. Type it in and press Enter.

Step 6: Confirm Successful Reload

Once the command executes, the MacFuse kernel extension should be reloaded successfully. You should see relevant system messages indicating that the extension has been loaded. This indicates that the fix has been applied.

Step 7: Test Cryptomator

Now that the MacFuse kernel extension has been reloaded, launch Cryptomator and attempt to unlock the vault that was previously causing issues. The problem with MacFuse hang should be resolved, and you should be able to access your encrypted files and folders without any further hindrance.


If you encounter difficulties unlocking a Cryptomator vault on macOS due to MacFuse hang, the steps outlined above can help you resolve the issue. By unloading and reloading the MacFuse kernel extension using Terminal commands, you can restore functionality and regain access to your encrypted vault. Remember to follow the instructions carefully and ensure you have administrative privileges on your system to execute the commands.
