If you own one of them
Whether to move is a different question from which is better. Each Mac has a page on it: what its successor changes (the newest Mac in its line where Apple sells one, otherwise the Mac this site treats as its replacement, which can be in another line), what it fetches and whether it still gets updates. Should I upgrade my MacBook Air M3 (15-inch, 2024)? · Should I upgrade my MacBook Pro M3 (14-inch, Nov 2023)?
