I mean I ran my 2011 mbp into the ground, until the point that the SMC’s fan channels stopped working and it always rebooted at exactly 00:00 for no apparent reason, and never had issues with apps not being able to run on a 3 year old version of the OS. After that 3 year period most apps still worked, although some would indeed start targeting newer api’s.
I know it was volunteering work, and I don’t want to defend apple any further than strictly here, but saying they “murdered” the OS every 7 years is just straight up not true, that was all I wanted to say.
A UDM or Cloud Key Gen2 plus can also function as your recorder & protect app host
