[SOLVED] Apple iSight installation on newer (K)ubuntu releases

I want to share here my experience in conjunction with installing an Apple iSight camera under Kubuntu 18.04 LTS running in native EFI mode (dual-boot). In short, my iSight is working absolutely PERFECTLY! The tested system is an older (SSD, RAM, BT 4.0 and 802.11ac upgraded) Apple iMac aluminum computer running the most recent supported Mac OS X version 10.11 El Capitan. Here starts my first note, - more recent iSight Firmware Tools versions (like 1.6-2build1) are absolutely able to extract the iSight firmware also on newer Mac OS versions. Certain website claim that this is NOT possible and it will fail on Mac OS X 10.8.6 Snow Leopard and newer. Well, according to my latest test this is no longer true, - I can confirm that it worked for me perfectly at OS X 10.11 El Capitan. So it seems that the following article should be updated: https://help.ubuntu.com/community/Ma...am/AppleiSight

So what were my exact steps?

1. Locate the exact path of the "AppleUSBVideoSupport" file at the "Macintosh HD" volume. It is essential to get the correct path-name, otherwise it will fail. In my case, with (K)ubuntu user profile called "franz", the path was: Note, you have to change the name "franz" with the name of yours (K)ubuntu user profile!

2. Download the iSight Firmware Tools with the following command and follow the installer instruction. As mentioned, it is fundamentally important to enter at the firmware extraction the correct path of the AppleUSBVideoSupport file. 3. After that, a webcam app should be installed, - I decided me for the following one: The iSight webcam should be now fully working. Because my Kubuntu 18.04 LTS is running in native EFI mode, I haven't to power off the iMac and boot it up again. However, this seems to be necessary if Linux is running in Bios/CSM mode. I can confirm this for an even older white polycarbonate iMac model. The camera only worked after reboot into Mac OS X and running (once) the Photo Booth app.

Note, - if the firmware extraction fails, you have to remove at first the entire iSight Firmware Tools package with the following command. After that, the package can be installed a second time.
