- Processor
- Intel Core i3 1.1GHz / i5 1.1GHz / i7 1.2GHz (10th gen)

Recovery methods for this Mac
- Logical recoverySoftware-level recovery from a working deviceYes
Once the Mac runs and is unlocked with your password, deleted files and damaged APFS volumes can be recovered. TRIM clears deleted data quickly.
- Physical recoveryRepairing failed hardware to read the dataYes
Liquid damage, shorts and failed power circuits on the logic board are repaired at component level.
- Chip-on recoveryReading the NAND in place, through the original controllerMain method
This is how your data comes back. In some cases we move the T2 chip and its NAND together to a donor board.
- Chip-off NAND recoveryRemoving the memory chips and reading them directlyNot possible
Not possible. Every block is encrypted with a key held inside this Mac's T2 chip. NAND read on its own is unreadable, by us or anyone else.
About this model
- NAND is soldered and hardware-encrypted by the T2 chip.
- Data is only recoverable through a working logic board/T2 (e.g.
- Target Disk Mode or board repair), never by chip-off.
- Last Intel MacBook Air.
