Apple's typical device refresh optimal for new college students? Long-story-short: When does apple typically update their hardware?



As a prospective college student, I'd want to get new devices before college begins, but I'd also prefer to have the most up-to-date once I actually begin college.

Colleges that I've looked into typically start in Fall, so I was wondering whether Apple typically updates devices in late-Summer. Or, do they inconveniently update it after most colleges start?
