I don’t know when it happened but running osxfuse 2.8.0 and encfs version 1.8.1 on Mac OS X Yosemite 10.10.5 and then trying to launch a VMWare Fusion 7.1.2 VM causes the following errors:

“Could not open /dev/vmmon: No such file or directory”


“Failed to initialize monitor device”

To get your VM to run after running encFS over osxfuse you need to unload the osxfusefs kernel module.

sudo kextunload /Library/Filesystems/osxfusefs.fs/Support/osxfusefs.kext

And then rerun VMWare Fusion you should then be able to start your VM

Alternative to encFS over osxfuse

So as a work around you can install Safe from

Important: To get Safe version 1.4 to work you have to enable FileVault (System Preferences => Security & Privacy => FileVault => Turn on FileVault).

What happens if you try to run encFS/osxfuse after you successfully run VMWare?

If you run VMWare and start your VM and try to run encFS/osxfuse you get:

EncFS Password: 
/Library/Filesystems/osxfusefs.fs/Support/osxfusefs.kext failed to load - (libkern/kext) kext (kmod) start/stop routine failed; check the system/kernel logs for errors or try kextutil(8).
the OSXFUSE file system is not available (71)
fuse failed. Common problems:
 - fuse kernel module not installed (modprobe fuse)
 - invalid options -- see usage message

    were you able to open directories created by encfs with safe?
