Sadly, my 2011 MacBook Pro won’t update to these later versions, so I just have to leave it running for months at a time.
Perhaps when the keyboard fails, someday, I’ll replace it, instead of just upgrading the RAM and drive.
Kidding aside, I would like to get a newer version someday with better screen resolution and size, but Apple seems to have many missteps to recover from the last 5 years or so.
I’m assuming an implied “/s” at the end of your comment.
