TL;DR – Rezultat Ars Technca istraživanja pokazuje da je prosek cca. 7 godina ažurranja, ili oko 5 nakon što Apple prestane s prodajom, mada je interesantno da ima varijacija od modela do modela, prema godini proizvodnje.

Ars Technica je napravila i tabelu sa pregledom podržavnih verzija za maltene sve Appleove računare: https://docs.google.com/spreadsheets/d/1-Ksovu-81EA7Z5m7lscjWnJussx6cTrNOUjJiGi3rCQ/edit#gid=712463390

Here are some highlights from our data that are more difficult to visualize:

• For all Mac models tracked, the average Mac receives almost exactly seven years of new macOS updates from the time it is introduced, plus another two years of security-only updates that fix vulnerabilities but don’t add new features.
• The average Mac receives updates for about 5.5 years after Apple stops selling it. Buying a Mac toward the end of its life cycle means getting significantly fewer updates.
• Macs that are sold for an abnormally long time—the 2014 Mac mini that was available until 2018, the 2013 Mac Pro that was available until 2019, or the 2015 MacBook Air that was available until 2019, to pick three examples that Ventura doesn’t support—don’t get software updates for longer just because Apple sold them for longer. This differs from the timeline Apple uses to provide hardware repair services, which is determined based on “when Apple last distributed the product for sale.”
