Confirmed to work on MacBook Pro (13", Late 2013) by Hamish McIntyre-Bhatty.
# Known issues
* Suspend / resume doesn't work properly. Suspending must be done with the device closed.
* Suspend / resume doesn't work properly. Suspending must be done with the device closed. (See: [workarounds](#workarounds))
* Only firmware version 1.43 is known to work with the driver. Newer versions might also work but 1.43 is highly recommended.
* Due to a bug in cpio 2.11 the firmware download script doesn't work. cpio 2.12 or later is required. (See: https://bugzilla.redhat.com/show_bug.cgi?id=1318084)
* The driver will complain about 1871_01XX.dat (or similarly named) files missing. This error can be ignored. The .dat files contains sensor calibration settings that will improve image quality. The error looks something like this:
```Direct firmware load for facetimehd/1871_01XX.dat failed with error -2```. Ignore it.
* No /dev/video0 device appears after loading the module. This can be because the bdc_pci module is already loaded. Make sure you unload or blacklist bdc_pci before loading the facetimehd module: ```modprobe -r bdc_pci```.
* A reboot may be required after installing and compiling the modules, as was the case on a MacBook Pro (13", Late 2013).

# Workarounds
* You can use [facetimehd-toggle](https://github.com/Chamal1120/facetimehd-toggle) to toggle webcam only when needed. This way the driver will be unloaded when not in use and suspend/resume will work properly.
