In my world as a manager, employees come first. I have often wanted to finally buy a new computer, but when I unpacked the ordered goods, my own wishes were always overwritten by the wide eyes of my colleagues. Each time, I gave up, passed on what had been delivered - and remained stuck with my MacBook "from back then".
When I set up the old computer, I replaced the OSX operating system with the Linux distribution Manjaro. In the process, I became painfully aware for the first time that, in addition to open-source software, hardware also plays a decisive role. The components built into Apple devices are mostly proprietary. Thankfully, people had sacrificed their lives to reverse engineer the initial design of the finished product, thus enabling at least rudimentary support of the interfaces under Linux.
As far as the camera was concerned, the substitute resulted in a significant loss of quality: for years, I was indeed the motivation for many participants in video conferences to "listen to Queen again". My appearance reminded them too much of the legendary second album cover of the British rock band.
Yes, that was not a cool filter. It was the best the driver could get out of the hardware built into the MacBook.
