This is a very useful activity to understand if you haven't updated for a long time.

In essence, it will give the ports tree you had a year ago. Then you can reinstall your ports from that date, get going again, and then do things in a more controlled fashion.

I just like the older OSes -- this MacBookPro I'm on now has Sierra installed, but I prefer SnowLeopard. Apple must hate me :>
