I have 2 external hard drives which are formatted to NTFS because I use them on Mac and Windows. On my previous Macbook I used NTFS-3G and Macfuse and it was fine, but now i'm having problems on my new machine running Mavericks. It seems now that you don't need these drivers any more on Mavericks and the drive picks up on it's own, however I only have read permissions. I've researched it and tried installing the two drivers mentioned above that I used before but it gives mount errors every time. I'm finding the only way to solve it is to install yet another driver, called OSX Fuse, and another small file, basically following the procedure here - http://www.makeuseof.com/tag/solving-the-read-only-external-hard-drive-problem-on-your-mac/ (scrolls down to just before the conclusion) This is a long winded solution that solves the problems but creates yet another problem - slow shut down times where the system just seems to hang before turning off. I've found the problem and it's when the NTFS 3G driver and OSX Fuse are installed together. As soon as I remove one or the other the shutdown hang problem goes away but the mounting problems come back, it's driving me mad. I know for a fact that all these things need to be installed. I've had bad experience using the Paragon software before and am not going to pay for something just to solve this problem. I've heard though that formatting them as exFAT solves the problem and works on Mac and Windows but there's less chance of recovery if something goes wrong. That, and on one of the drives i'll be running Steam games off it so speed is a big factor. Any ideas?
