Thank you for viewing. This is a MacBook Air (2020 model) with the Apple M1 chip. I am selling it because I have upgraded to a new PC. ✅ Key Features Unlike the standard model (8GB memory / 256GB SSD), this is a high-end model customized (CTO) at the Apple Store with 【16GB memory / 512GB storage】. The combination of the M1 chip's performance and 16GB of memory allows for very comfortable operation even with high-load tasks such as video editing, design, and running multiple applications simultaneously. (I used it for video editing with Final Cut Pro and online meetings on Zoom, but I will delete them before sending.) With 512GB of storage, you are less likely to be troubled by insufficient capacity. ■ Product Condition • Operation: I was using it without any problems until just before listing. Touch ID, keyboard, camera, speakers, etc., all work normally. • Battery: The maximum capacity is 88%. (As of listing) It has enough battery life for normal use. • Appearance: I have been using a cover purchased from the Apple Store (pictures 2-3) since I bought it, so I think it is in very good condition with no noticeable scratches or scuffs. Picture 1 is without the cover. The screen image also shows a black vertical line on the right side. I think the display is malfunctioning, but I haven't had it repaired because it didn't affect usage. ■ Specifications • Model Name: MacBook Air (M1, 2020) • Color: Silver • CPU: Apple M1 chip • Memory: 16GB (CTO) • Storage: 512GB SSD (CTO) • Display: 13.3-inch Retina display • Keyboard: Japanese (JIS) layout ■ Accessories • MacBook Air body • Genuine AC adapter • USB-C charging cable (the original cord is broken, and I purchased a replacement from Amazon) • Original box • Apple Store genuine cover • UGREEN USB, SD, and HDMI adapter ■ Shipping • I will hand it over after turning off "Find My," signing out of iCloud, and performing a clean install (initialization) of the OS.
