I think “end support” in the title is misleading. From the article:
Based on Apple’s warning, you can expect that macOS 27 will drop support for all of these legacy machines, and therefore macOS 26 will be the last compatible version. These devices will continue to receive security updates for another three years, however.
Unless your parents want the latest features they’ll probably be fine for a few more years.
I have, but only for a few channels I really care about which produce high quality videos and don’t upload very often (like every few weeks at most).
