rEFInd error on install

[socalrooster]

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 install.sh 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.

My first recommendation is not to install Kali it's not intended to be run on metal and all the tools contained in Kali are in just about every distro's repo. My second is if you want to try the stuff that Kali is for you need to be comfortable in the terminal and most of the tools are cli based. My third is if you want to be proficient in the pen-testing world you install a few distros in virtual box and actually use and break them, then move on to something with a cli based installer so you have to put your system together, that will help you understand why those tools work.

..when I run install.sh I get this...

Nothing wrong with your log. You have LVM so it has installed refind to /EFI/BOOT. That is correct for Yosemite.

If you look in terminal you'll see something like this:

$ mkdir /Volumes/esp
$ sudo mount -t msdos /dev/disk0s1 /Volumes/esp
Password:
$ cd /volumes/esp/EFI/BOOT
$ ls
bootx64.efi		icons			refind.conf
drivers_x64		keys			refind.conf-sample

Try putting in a bootable USB - rEFInd should see it automatically.

If it does all you have to do is make yourself a partition using disk utility and install your linux to it from your bootable USB key.
