Not true. If MacOS lacks physical RAM, it will get extra from swap on SSD, and will continue to function just fine.
Well, of course all modern OS-es use swap when they don't have enough memory. But if it means they "function just fine", why Apple doesn't sell their entry level with just 4 GB if it really makes no difference?
Well the comment you're responding to did say "until it starts swapping out". Was that added after you wrote your comment?

I think so - it didn't say that before I refreshed the page about a minute ago.
Yup, wasn't there when I added my answer.
Until you wear out your TLC / QLC NAND chips. Then the whole computer is e-waste.
