I never had to visit Apple Store for Macs after 60 days.You’re confusing initial AppleCare sign up vs. AppleCare renewal for those who already had it. You have up to a year to add AppleCare from date of purchase though anything after 60 days requires a visit to an Apple Store Genius Bar for a quick screening. This applies to iPhones, iPads, and Macs.
Renewals were until now limited to 30 days after expiration.
