macOS Big Sur encryption at the file level

February 28th, 2023, 9:49

Dear HDDGuru Community,
I have a strange case of encrypted SSD drive from a Macbook Pro (512GB). Drive is obviously not encrypted by FileVault and does not have any firmware issues or bad sectors. When I mount the drive to PC3000 I can get a list of all files/profiles but all data are encrypted, nothing found via RAW recovery - all files have incorrect file headers. I have a password for the decryption but I was not asked to enter the password. I assume it is a new type of encryption at the file level coming with macOS Big Sur. When I connect the drive to a Mac I also get the whole structure but all data are damaged.
I have also tried many other tools for Windows as MacDrive, UFS, Paragon, but the result is same - structure is available, but data are damaged. Has anyone encountered a similar problem?

Thank you very much for any help!

Oliver

have you tried to boot the Mac as target mode ?
