Installing Yosemite broke my install with their stricter rules on code-signed kernal extensions for security reasons. To fix it, you need to run the following 3 commands in terminal before installing/reinstalling: 1) sudo nvram boot-args="kext-dev-mode=1" 2) sudo kextcache -system-prelinked-kernel 3) sudo kextcache -system-caches after the first command you will need to enter your password because of 'sudo' (super user do) this disables the security check. the other 2 commands just clear your cache of any old versions of this kernel extension to give you a fresh slate. After you install/reinstall you'll restart and things seem to be working. I suspect that this will be broken in the next update because this uses the /System/ folder which apple will be phasing out 3d party use of that folder.
I've tried to unistall this app... I tried to used the file 'uninstall' but nothing happened. There is nothing on this folder /System/Library/Extensions/ related to ntfs-free anymore. And I still get the error message after connecting my external HD. How can we really uninstall this app ?! Is there another file we should delete ? Has this app deleted any file which it wasn't supposed to ? If someone succeed in unistalling, please let us know !!
Its not working with OS X Mavericks and Yosemite(Beta).Don't install because after installing you will not able to read any NTFS.
I can verify that NTFS-FREE works fine at first - but for larger drives it simply crashes the system. The limit seems to be around 1.5-2TB. Also there is no way to uninstall it (unless you know how to track down kext files and removing them manually) Stay away unless you're sure you can clean up the mess it leaves behind - my recommendation for ParagonNTFS stays.
