Ever forget to add AppleCare to your iPhone, iPad, or Mac in time? Apple is dramatically changing the grace period for adding AppleCare+ on most products starting today. The news is part of Apple’s AppleCare One announcement. The new AppleCare One bundle offers the most flexible grace period for adding additional warranty coverage. While coverage can be added at the time of purchase, AppleCare One also allows you to add device coverage to products purchased within four years. Once added, coverage is provided for the length of the subscription. Devices can be added as long as they’re in reasonable condition. For example, Apple won’t allow an iPhone with a shattered display and no AppleCare+ coverage to be added. Instead, the display would need to be repaired before it was eligible for AppleCare One. Condition checks may require submitting photos of devices to verify their state when adding coverage remotely. Four years is a dramatic difference compared to the old 60-day window or when AppleCare had to be purchased in a box at the time of purchase.
