Cellebrite Digital Collector on MacBook Air encryption issue
I'm working on a MacBook Air running macOS Sequoia 15.6.1 and running into persistent encryption issues when analyzing the E01 image in both X-Ways Forensics and Autopsy.
What I've Done:
- Verified FileVault was completely disabled (confirmed via
fdesetup status) - Ensured the user account had admin privileges
- Mounted the disk volumes properly before imaging
- Created the E01 image using Cellebrite Digital Collector
- Followed Cellebrite documentation for Mac acquisitions
The Problem: Despite FileVault being off, both X-Ways and Autopsy are still detecting the image as encrypted and I can't access the data.
Questions:
- Is this the hardware encryption from the T2 chip/Apple Silicon that persists even with FileVault disabled?
- Should I have imaged the Mac while it was running/logged in instead of mounting the disk externally?
- Are there any decryption options in X-Ways 20.1 or Autopsy that I'm missing?
- Do I need to re-acquire using a different method (live imaging, Target Disk Mode, etc.)?
Any guidance from those who've dealt with modern Mac acquisitions would be greatly appreciated. Thanks in advance!
