This guy sounds like any mechanic.
My good buddy’s dad was a mechanic for nearly his entire life. Every single car, no matter the make, model, price, luxury, or practicality was a “shitbox”. Every. Car.
Every frame a painting? No, every car a shitbox.
When you get inside the machine for too long, you start to see the flaws. You become aware of every decision, every dollar saved, every process demystified, every marketing term uncovered.
I admire his crusade to put himself out of a job for the betterment of the Apple buying public. It’s a noble cause.
As far as your comment, Bob Zelin, about third party drivers, that is definitely more of a concern for me. I just recently switched to High Sierra, only because 10.4.1 required it. I had some issue getting SAN clients up and running. Nothing too major, nothing unsolvable, but definitely not as plug and play as it has been in the past. When working with support, they mentioned that Microsoft has enabled more strict changes in driver signatures for third parties. So, it’s not only Apple that is doing this. It seems to be a current security trend.
Also, my Wacom drivers were blocked upon reinstall. That was super weird.
