Fully functional 11-inch MacBook Air Early 2015 model MJVM2J/A, with a new battery and macOS Sequoia installed (photo ②). Key specifications: 1.6GHz dual-core Intel Core i5 (Turbo Boost up to 2.7GHz), 3MB shared L3 cache, 4GB 1,600MHz LPDDR3 onboard memory, 128GB SSD with Sequoia (macOS 15.7.1) installed, Intel HD Graphics 6000 graphics and video, USB 3 (up to 5Gbps) x 2, Thunderbolt 2 (up to 20Gbps) x 1, and a super lightweight 1.08Kg design, making it a very convenient model. While it appears very clean in photos ③-⑩, upon closer inspection, there are some scratches around the red line in photo ⑩, and some scratches on the LCD screen in photo ⑪. The keyboard shows no shine, only slight wear (photo ⑫). The LCD screen is not noticeable during use, but the keyboard imprint may be visible when the power is off. The backlight is good and there are no issues (photo ⑬). The inside is also in good condition, with no dust on the fan (photo ⑭), and of course, the Hardware Test shows no problems (photo ⑮). As mentioned earlier, the battery is a third-party new one from 2021, with only one charge cycle and 109.1% (5,002mAh) capacity, as shown in photo ⑯, indicating excellent condition. However, since it's a third-party battery exceeding 100%, the Hardware Test might prompt a battery replacement when it drops below 100%. Despite this, the system report in photo ⑰ clearly recognizes it as "Normal," so there are no issues in use. The biggest advantage is that the new, high-capacity battery will last a very long time. Included accessories: Only the original AC adapter is included. The cable has yellowed with age as shown in photos ⑱⑲, but there are no issues with its use.
