Thank you. Can you please proceed with the following steps for further troubleshooting:
1. Boot to Recovery (hold Cmd + R upon Mac boot)
2. Open Terminal via 'Utilities' menu
3. Execute: csrutil disable
4. Boot to macOS natively. Open Terminal and execute: sudo dd if=/dev/disk0 of=~/disk.bin count=2048
5. A file disk.bin will be created at your user's home directory.
6. Please zip the file (right-click > Compress) and upload it to any convenient file share, then reply to me back.
7. Boot to Recovery again to enable System Integrity Protection back: csrutil enable
Thank you in advance!
