Retina, 13-inch, 2018 MacBook Air with 1.6 GHz Intel Core i5, 8 GB RAM, and 256 GB SSD. Rose Gold - Model: MacBook Air - Processor: 1.6 GHz Intel Core i5 - Memory: 8 GB - Storage: 256 GB SSD - OS: Sonoma 14.7.4 US keyboard (Japanese input possible through settings) Purchased in 2018 at an Apple Store in Sydney, Australia, where I was living at the time. Used for about a year, the fan would make noise while charging, but after initializing for this listing, the noise is gone. As shown in the 13th photo, the battery status is "Service Recommended." Excerpt from Apple Support: Service Recommended: The battery's ability to hold a charge is significantly reduced compared to when it was new, or the battery is not functioning normally. It is safe to continue using your Mac, but if you need battery service or if the battery's charge capacity is reduced, have the battery evaluated at an Apple Store or an Apple Authorized Service Provider. Or contact Apple. The battery is functioning normally, so this message likely indicates a reduced charge capacity. I have been using it without problems, but please consider this when purchasing. I have used a case since I purchased it, so the body is in good condition. I will include the case if you wish. (It has some scratches and minor damage.) Accessories (included if desired) The power adapter is Australian specification. I used it with a conversion adapter for use in Japan, so I will include it as is. It is slightly deformed, but it charges. To prevent swapping, returns are not accepted, so please consider carefully before purchasing.
