After quite some weeks where I had to use my old Logitech headset again instead of my fancy Audient audio interface plus the Shure mic I finally tried to find the reason why my mic isn’t recognised in teams. The interface is listed normally in the dropdown and all other apps also work absolutely perfect […]

Performance on MS Teams was very bad on M1 MacBooks compared to other applications. But Microsoft is working on a native osx-arm64 version which I installed. And I have to say that I am blown away from the speed improvement. It’s like day and night. If you’re interesting in trying out non released Teams versions

With a release date in 2018 I expected to have my Xiaomi Mi Mix 3 at least for a few years – if I manage not to crush it like its predecessor. Already in 2020 I had to learn that Xiaomi stopped support for the former flagship device. Really very disappointing and not a big
