MacBook Air 1.7GHz 8GB 960GB SSD 11-inch

Fully functional 11-inch MacBook Air (Mid 2012) with SSD upgraded to a 960GB Transcend JetDrive.
Main specifications include: 1.7GHz dual-core Intel Core i5 (up to 2.6GHz with Turbo Boost), 3MB shared L3 cache, 8GB 1600MHz LPDDR3 onboard memory, a large 960GB SSD with Sequoia and Caterina installed (Photos ①②), Intel HD Graphics 4000, 2x USB 3 (up to 5Gbps), and 1x Thunderbolt 2 (up to 20Gbps). This is a very convenient and ultra-lightweight model at 1.08kg.
As shown in Photos ①-⑩, this MacBook has been used with great care and is in beautiful condition, with only minor scratches on the rubber feet (Photo ⑪).
The keyboard has only minor scuffs (Photo ⑫), and the LCD is clean (Photo ⑬). However, there is one spot of rubber deterioration near the camera (Photo ⑭). The interior is also clean (Photo ⑮), and the fan is free of dust, indicating it has been well-maintained (Photo ⑯). The battery has 231 charge cycles and 88.5% capacity (4443mAh), so it can still be used (Photo ⑰ - manufacturing date is an app bug). It has passed all tests on the older Apple Hardware Test (Photo ⑱). However, after replacing the SSD with a 960GB Transcend drive and installing OpenCore Legacy Patcher, running Apple Diagnostics (Command D) results in the error shown in Photo ⑲. This appears to be due to firmware updates in macOS that are no longer compatible with the older Apple Diagnostics (TestSupport.efi), as discussed here:

While this does not affect functionality, please be aware of this issue.
This is a beautifully maintained model with nearly 1TB of SSD storage, so it can still be used for a long time.
Accessories included: AC adapter only.
