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