I updated my MacBook to OS X Yosemite version 10.10. Everything seems to be fine... apart from:

  1. My WD hard drive won't open now - it appears on screen, allows me to enter the password to unlock and then give me this message:

NTFS-3G could not mount /dev/disk2s1 at /Volumes/My Passport because the following problem occurred:

/Library/Filesystems/fusefs.fs/Support/fusefs.kext failed to load - (libkern/kext) link error; check the system/kernel logs for errors or try kextutil(8). the MacFUSE file system is not available (71)

  1. My iPhoto's has a 'no entry' symbol over it and it won't let me access it... does this mean I have lost all of my photos!?!?

Any advice on these 2 things would be much appreciated. Many thanks

Unsigned kexts are no longer allowed to run by default in Yosemite.

Solutions include...

  • upgrade to one of the [paid] NTFS apps that still work - Tuxera or Paragon
    Requires you to fully uninstall NTFS-3G first

  • disable the Mac's kext policy - easiest way might be to install TRIM Enabler, which will do it for you [though I don't know if it would install with no SSD present, never tested]

  • or the long way - [this is untested, method from cindori, the makers of TRIM Enabler - it might only be for that app]
    Boot your Mac in Recovery Mode by holding ⌘ Cmd R during boot
    Open the Terminal from the menu bar
    Run these commands, replacing YourDisk with the name of your Mac disk

    • rm -rf /Volumes/YourDisk/System/Library/Extensions/IOAHCIFamily.kext
    • cp -r /System/Library/Extensions/IOAHCIFamily.kext /Volumes/YourDisk/System/Library/Extensions/IOAHCIFamily.kext
    • touch /Volumes/YourDisk/System/Library/Extensions
    • kextcache -u /Volumes/YourDisk

    Wait until it finishes (can take up to 1 min)
