I have a MacBook Pro 2018, now I encounter:

I can’t partition my Mac disk to install Windows.
Disk Utility’s First Aid shows no errors.
Partitioning fails with “Storage system check exit code is 8”.
What can I deal with it?

This may due to:
APFS quirks, T2 Security chip, some hidden snapshots, disk layout issues, Windows Boot Camp compatibility.

There may be something wrong with your drive, you’d better recover the data as soon as possible.
iBoysoft Data Recovery for Mac is highly recommended, which can recover data even if your disk is problematic.

  1. After installing, open it.
  2. Choose the drive on the left, then click Search for Lost Data.
  3. After scanning, preview the data and click Recover to save the needed files.
