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, USB 3 (up to 5Gbps) x 2, Thunderbolt 2 (up to 20Gbps) x 1, and weighs only 1.08kg, making it a very convenient and lightweight 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 might 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 new 3rd party battery 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 3rd 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 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. The cable has yellowed with age as shown in photos ⑱⑲, but there are no issues with its use.
