To recover data from a dead M1 MacBook Pro, what you need to know is if you have no backups in your MacBook or other devices, there's no way for you to recover your data after you change the logic board.
After your logic board has been fixed, you still can try professional data recovery software to recover your data. I recommend you try iBoysoft Data Recovery for Mac.
iBoysoft Data Recovery for Mac is a powerful tool for you to recover your data from USB flash drives, SSDs, SD cards, and HDDs. It is fully compatible with M1, M1 Pro, M1 Max, M2, and T2 chips. And it also supports you to recover data from an unbootable Mac.
- Free download and launch iBoysoft Data Recovery for Mac.
- Choose the drive you lost data and then click Search for Lost Data.
- Preview the search results and click Recover.
- Check if you get back all the data.
If you still cannot get back your data, you can take your MacBook Pro to other professional local offices to get help.
