    I have a really nice 3TB 2.5" external drive that I use between my Linux boxes, my work MP, and my daughters Windows PC, and supposedly my 10.11 iMac. The drive works fine on everything but the iMac. I tried google and it sorta told me to input defaults write com.apple.DiskUtility advanced-image-options 1 into the terminal and I did and it still doesn't work. Does anyone else have issues with an exfat external in El Cap?

    Did you use Windows to format the drive?

    Is the external disc shown in Disk Utility when it's connected to your Mac?

    Interesting, have you tried clearing the drive and formatting it using exFAT on Windows?

    Please do the following:

    Note: The following procedure must be performed on an OS X user account that has administrative privileges.

    1. Disconnect the external disc from your Mac.
    2. Open Terminal.
    3. Enter the following:

      sudo tail -f /var/log/system.log
    4. Enter your OS X user account password if you're prompted to.
    5. Connect the external disc to your Mac.
    6. Include any relevant messages printed to the Terminal window in a reply to this post.
