Cannot read from TimeMachine backup

[Tex-Twil]

Hi,
I have a TimeMachine on an external disk and a freshly installed macOS. I don't want to restore the entire TM backup but just pickup some files.

I noticed that I can copy the files and folder using Finder but other apps can't even read the Backups.backupdb folder.

When using Terminal:

$ whoami
jan

ll /Volumes/TimeMachine
total 216
dr-xr-xr-x+ 6 jan  staff     204 Apr 22  2018 Backups.backupdb
-rwxr-xr-x@ 1 jan  staff  107524 Feb 27  2018 tmbootpicker.efi

ll /Volumes/TimeMachine/Backups.backupdb/
ls: : Operation not permitted

sudo ls  /Volumes/TimeMachine/Backups.backupdb/
ls: : Operation not permitted

How come that the user cannot read or list the folder contents even if it has the R and X permissions?

I’m not sure of the answer but I’m assuming you’ve tried to open the drive with Time Machine directly as opposed to trying to directly access the files?

Couldn't you use Migration Assistant (found in Utilities) to migrate the files you want from the TM backup? If Migration Assistant cannot read the backup either, then there would seem to be something corrupt about the backup.
