Not sure if this matters for your overall point, but mac os updates are downloaded asynchronously, it's their installation that locks up your computer for 20 minutes. Sounds like an inconsequential detail, but I can't readily think of any recent experience where I actually did have to wait for a download to finish before I could continue doing anything. Most things are either streaming or background, nowadays. Perhaps Steam?
