I have successfully installed Kali 2.0 on my Macbook Pro retina 2015 model running El Cap via dual boot. I do have some experience with Ubuntu etc, and thought I'd try Kali for multiple reasons.
Now, I thought everything worked perfectly, until I noticed there was no WiFi icon in the menu bar. Well, no problem I thought initially. I just grabbed an ethernet cable and connected to my home network without problems. I downloaded the appropriate driver for my network adapter, the Broadcom 4360. However, when I attempted to install the package, the terminal spat out the error message that the package dkms was not installed. Okay great, that can also be installed manually I thought. After trying that, I got yet another error module init tools not installed. Then I figured that this is not just a problem with my Broadcom thingy, but perhaps with my Kali install.
Things I tried:
- Apt-get update, which also spat out errors, mostly 404 not found etc.
- Reinstall headers, also errors (unable to locate headers for kali_4.0.0 etc.)

Error file is here, I believe the most pressing error is the last one (they are separated by !!!!'s): http://www.megafileupload.com/egdH/errors.
