I've met the problem again!
Now, I using the below to fix that:
For me the following steps work:
Verify that Terminal has Full Disk Access: System Preference > Security & Privacy > Privacy > Full Disk Access
Run sudo kextunload -b io.macfuse.filesystems.macfuse
Also, please refer this and this.
I meet the same question. I had just upgraded my Mac from
12.5.1, the VeraCrypt worked fine. But when I've accidentally upgraded my Mac from
12.6.4. the VeraCrype got this trouble:
Kext load failed ~60349477007
mount_osxfuse: the file system is not available (255)
My VeraCrypt version is
VeraCrypt 1.24-Update8, my macOS is
This trouble happened maybe because:
1.osxfuse do not installed correctly;
2.osxfuse APP and Kext files are corrupted;
3.osxfuse APP and Kext files are not compatible with the current system version;
4.Insufficient permissions given to osxfuse APP and Kext files.
(If it is confirmed that it has been installed and it is not because of the system version problem,
it is recommended to check the permission settings of the system)
my trouble match the tips
First, I've just use
brew to install the latest
brew install osxfuse, but the latest
osxfuse 3.11.2 App is not suitable for
macOS 12.6.4, so I have to use
osxfuse has been succeeded by
macfuse as of version
4.0.0, if your CPU was
Apple M1, you also could choose
brew to install
macfuse via command
brew install mmacfuse, then go to "System Preferences -> Security & Privacy -> General" and see if there is an allow button at the bottom for 'Benjamin Fleischer". If it is there, click on it and then reboot the machine.
Third, if VeraCrypt works, END! if not, then refer this.
