A:AnswerMacbooks are not locked (since NONE have a cellular connection built in) and should work in any country but you'll have to provide your own mobile connection in any country e.g. from your cell phone as a hotspot.
A:AnswerI bought an Open Box and the Apple warranty had started from the initial purchase date (from the original purchaser). This reduced the Apple warranty by about 3 weeks from the 1 year for me. Thus I got about 49 weeks of the Apple warranty (vs. 52). Best Buy apparently will make up the rest of the year since your purchase but that won't help you in India. Of course you can add AppleCare+ to give you longer Apple warranty cover just as any Apple purchaser can.
TL/DR - you should get most of your Apple warranty with whatever international privileges that offers but will depend on how long the machine has been sitting open boxed. Best Buy will make up the rest (in the US).
A:AnswerThere is a 1 year manufacturer warranty that covers the software. If you purchased AppleCare, it could be a 2 or 3 year plan that covers the physical components, hardware and software.
