Hey there Kathryn,

Thanks for letting us know. I'm glad to hear that you are lovin' your MacBook Air. If there is no error code or issue for you when booting up the MBA, then it should be fine. But in my opinion, I would still try to troubleshoot the issue with the seller to see if the MBA can boot up faster. Please contact the seller directly through the "My Orders" tab on Back Market.

I hope this answers your question! Let me know if you need anything else. I'm always happy to help.

Regards,
Dominick from Back Market
