can i upgrade from El Capitan directly to Big Sur
Will a new OS fix the expired security certificate problem with Let's Encrypt?

1. It depends on what iMac model you have.
2. Yes.

Back up your data and check your applications for compatibility before proceeding. In particular, 32-bit oftware won't run in Catalina and newer; if you need it, upgrade to Sierra, High Sierra, or Mojave instead.

I ended up installing Sierra OS, which I hadn't done because my bookkeeping program would not have worked on it. The upgrade (although I'm still a long way from Big Sur) fixed the Let's Encrypt SSL glitch that showed up at the same time as the problems with the Chrome update. I figure they were connected. Anyway, all is fixed. Thank you everyone!
The info page says my Mac is compatible (iMac, Retina 5K/27"/Late 2014).
So basically, I just download and install?
And I have the required 35G memory available.
Will those OS still fix the SSL problem? (thanks a ton, Niel!)
