Getting the driver working is two steps:
* [Firmware extraction](#firmware-extraction): Either extract the firmware from OS X (the bootcamp one is unsupported at the moment) or from OS X packages as described [here](/patjak/bcwc_pcie/issues/14).
* [Firmware extraction](#firmware-extraction): Run the script to download and install the firmware from Apple.
Gentoo users using the [ebuild](#get-started-on-gentoo) skip this step.
* [Installation](#installation): Installing the driver itself.

## Firmware extraction
You want to dump the FaceTime drivers while still under OS X. Commands below works on OS X 10.11.2:
* Download the driver (zip version) and extract it
* Under bcwc_pcie-master/firmware edit the "extract_from_ox.sh" script
* Line 2, replace `IN=AppleCameraInterface` with `IN=/System/Library/Extensions/AppleCameraInterface.kext/Contents/MacOS/AppleCameraInterface`
* md5sum is missing from a vanilla OS X 10.11 installation, replace "md5sum" by "md5 -r" (lines 7 & 24)
* Line 5, replace the hash value so it states: `OSX_HASH=ccea5db116954513252db1ccb639ce95`
* Save and execute the script: `./extract_from_ox.sh`
* Under bcwc_pcie-master/firmware type "make" and then as root type "make install"
* Result should be like:
```
$ ./extract_from_osx.sh

## If you get a corrupted image in Cheese
This is because some linux applications does not support high resolution cameras. To fix this go to Cheese settings and change the resolution to something lower. Then turn the computer OFF, and ON again. (Not reboot). This should fix the corrupted image.
