What does MacBookProX,Y refer to?
I would say there’s no consistency on when Apple revs major or minor and they often speed bump parts within the same X,Y family and have service bulletins to ensure compatible parts only get on compatible flavors of these.

You can count on larger numbers being released later and these are far easier to sort or compare in code, though, if you have to check you aren’t running on very old gear rather than check for specific functions / API to be available.

From my experience, these are monotonically increasing marketing numbers that let you guess the major CPU generation and sales period in a similar manner to the Marketing (Early / Mid / Late 2019) monikers that appear in all the Apple Documentation / technical specifications, etc..


Can a Mac&#39;s model year be determined with a Terminal Command?
