I bought this MBP a few weeks ago and installed NTFS-3G so that I could write to my windows formatted external HD. Everything was fine, I could use my external however I wanted. I've now clean installed SL again, and installed NTFS 3G, but it keeps saying that it cannot mount my HD, and looking in Sys Pref, I can see that MacFuse is 32bit, so I'm guessing that's the problem. The error is: NTFS-3G could not mount /dev/disk1s1 at /volumes/my book 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). However, I cannot for the life of me seem to find a 64bit version. I've uninstalled and reinstalled them several times and it's stil the 32bit version and I still can't mount. Could someone please link me to a 64 bit version that will work on SL and Lion? Alternatively, is there another NTFS read/write program that is free and is better than NTFS-3G? I was frustrated that it would write to the disk only very slowly (ie. 5gb took about 20 mins).
