Has anyone upgraded the internal storage on an M4 MacBook Air?
I have a MacBook Air M4 with 256GB internal storage and I'm considering having the onboard NAND chips replaced to upgrade the storage to 1TB or 2TB.
Has anyone here actually had an M4 MacBook Air NAND/storage upgrade performed?
I'm particularly interested in hearing from people who have:
- Upgraded an M4 MacBook Air from 256GB to 1TB/2TB
- Had the NAND chips replaced by a board-level repair specialist
- Done the upgrade successfully without replacing the entire logic board
If you've had it done, I'd love to know:
- What model/configuration you had
- Original → upgraded capacity
- Where you had it done
- Approximate cost
- Whether everything (macOS, FileVault, Touch ID, updates, etc.) continued working normally
- How reliable the upgrade has been since
I'm considering doing this rather than relying on an external SSD, so first-hand experiences with M4 specifically would be really helpful.
