    Hello fellow Mac users and experts.
    like many others i downloaded the new OS X, i have an older external harddrive that I used with my former Windows Pc, on Mavericks i did some "magic" to make my new Mac working together with my External harddrive.

    But here is the problem, after i installed Yosemite, i can no longer transfer files from the mac to the external harddrive.

    after searching the web and this forum, i haven't been abel to find a solution.

    Can any one help me ? :confused:

    Is the external hard drive formatted in the Microsoft NTFS format?

    If so, you'll need a 3rd-party extension on your Mac to be able to write to drives in that format. Maybe you had that extension on Mavericks, and it didn't come across after the Yosemite upgrade?

    Yes i did something by writing some code in xcode, but now it won't work with Yosemite, Do you know any 3rd party software that could help me with this?
    I couldn't find anything? :)

    And yes it is in Microsoft NTFS format :/ but i have too much stuff on it to do a re-install, because i dont have anywhere to storing all the files while doing it :/
