I understand I’m usually spoiled when it comes to how long Apple provides software support, but disappointed none the less.
Still I hear you, a 2015 machine isn’t that old.
(I have this same argument with all my DEVELOPER friends who are still running Win7. Ugh)
To see what's still 32-bit on your mac, go to:
Apple icon > About this mac > system report > applications > then click the 64-bit column to sort. No will be 32-bit apps.
