I wonder if it’s worse this year than usual because of the switchover to AppleSilicon? I have a 2013 Mac Pro that I use daily and it’s gotten all updates until this one. 9 years is pretty good. But I can understand wanting to end support for as many Intel machines as quickly as possible.
When Apple announced the transition from PPC to Intel, the PPC Macs only got two major updates before being EOLed. Even the Power Mac G5 (2005) only got two major updates before being cut off from support.
It should be noted, however, that those major updates had longer lifespans then. Snow Leopard, the first Intel-only version of Mac OS, came out in 2009.
