    Hello, I'm trying to install rEFInd (0.8.6, latest) on my early 2014 macbook air running OS X 10.10.2. The goal is to dual boot kali linux (for learning purposes), which would be installed from an imaged USB. However, when I run I get this:
    Installing rEFInd on OS X....
    Warning: root device could not be found
    Installing rEFInd to the partition mounted at /Volumes/ESP
    Found rEFInd installation in /Volumes/ESP/EFI/BOOT; upgrading it.
    Copied rEFInd binary files
    Notice: Backed up existing icons directory as icons-backup.
    Existing refind.conf file found; copying sample file as refind.conf-sample
    to avoid overwriting your customizations.
    WARNING: If you have an Advanced Format disk, *DO NOT* attempt to check the
    bless status with 'bless --info', since this is known to cause disk corruption
    on some systems!!
    Installation has completed successfully.
    Unmounting install dir
    umount(/Volumes/ESP): Resource busy -- try 'diskutil unmount'
    I'm brand new to any kind of "under the hood" computing, this is my first linux install attempt, not super comfortable with terminal, etc so if someone would be kind enough to point me in the right direction n00b style that'd be grrrrreat.

    Not sure what is on /Volumes/ESP but you could try to unmount it from the terminal with the following command:
    diskutil unmount /Volumes/ESP

    Then run rEFInd again and see if you still have the error.

    Just my 2c.
