Can I buy apple care from a third party seller after purchasing
I’d like to buy a Mac book air off Walmart. Can I buy Apple care up to 60 days after the purchase from Apple?
Are you buying Apple Care from a 3rd party seller or are you buying the Mac from a 3rd party seller?
You can buy Apple Care from Apple for a device that has been purchased from another retailer if its still within the 60 days of purchase yes. Walmart is an Apple Authorized reseller, so there should be no issue with purchasing Apple care for a device bought from them.
