With MDM solutions you can not only get software update management, but even full LOM for models that support this.
There are free and open source MDM out there.
There are even already some local AFM to Open AI API bridge project on GitHub - that lets you point basically any Open AI compatible client at the local models. Super nice for basic summarisation and completions.
Sometimes you have to marvel at what early desktop computers achieved with their kb’s of memory and mhz of cpu - less power than even a dishwasher might have today.
NotebookLM now supports Dutch - So you could load up some content of interest and 'join the studio' to talk with the hosts - I imagine that might be useful and fun.
I have an old iMac G3 from circa 2001 with classic Mac OS 9 on it for this purpose; there are great library websites out there with all educational games from the 90’s - no internet requirement in sight and loads of fun!
Negative - you can only remove audio devices with the audio-midi-setup that have either been added from the feature itself, or are using the underlying APIs for audio. None of my 3rd party audio devices (Sony MX-3000, Sony MX-4000, hdmi audio out, thunderbolt doc audio out) leverage those APIs, leading me to suspect this is actually fairly rare.
You can map default audio input/outputs with the tool, but removing the audio output is a different story.
