Macbooks Intel internal USB camera (iSight) need a little configuration to be detected on Debian. Tested and working on a 4,1 MacBook (Snow Leopard) with dual-boot Debian Jessie 64.
Install the iSight firmware
First, get the original MacOS firmware. When dual-booting the process is quite easy : mount the HFS partition to grab the needed file.
sudo mkdir /MacOSX sudo mount -t hfsplus /dev/sda2 /MacOSX
Once mounted, the following application will do the rest. Be careful though: a dialog box will open during the process, be sure that the path displayed begins with /MacOSX/System…
sudo apt-get install isight-firmware-tools
When it’s done you can check the firmware has been successfully retrieved:
Now, shut down completely the computer, restart it. It’s done.

Install Skype on Debian Jessie
Skype has a multiarch i386 deb installer for Debian: this means you need to allow i386 software installation on a 64 bit architecture.
sudo dpkg --add-architecture i386 && sudo apt-get update
Install Skype: it will announce several errors, you will resolve them next.
sudo dpkg -i skype-debian_188.8.131.52-1_i386.deb sudo apt-get -f install
Bravo, you now a have Skype and a working camera, let’s waste some time!
