A:AnswerAny non-activated (read: Find My was not activated on anyone's account on the device) Apple product comes with 60 days of Apple Care for free. But if you don't purchase Apple Care during that 60 days, once its past the 60 days, you will no longer be able to get it for that device. I highly recommend Apple Care since, while they are neutering it considerably, it is still cheaper to pay $15/month and a one time deductible of what ever they charge (usually less than $300 for screen repairs and larger repair jobs) than it is to pay outright what they charge for repairs without Apple Care. Screen repair for MacBook Air with Apple Care is about $300. Without Apple Care: $800. You decide what's best for you!
A:AnswerShort answer: Yes.
You will, however, need to download HP's app if you want to control the printer in more depth than just printing things out from your MacBook. That being said, HP usually offers a TON of discounts for first time customers on the app.
A:AnswerThe MacBook Air base model would be fine. I had the older Intel model but the fan bother me so I got the new M1 model. If you're patient, they go on sale for $799 at BB every now and then.
A:AnswerI have honestly never had an issue with this ever except when there was something wrong with the trackpad. With AppleCare or within return policy, it was fixed.
