mount-mac-apfs.sh

gistfile1.txt

#!/usr/bin/env bash
# Build apfs-fuse on Ubuntu and mount a Mac APFS container read-only.
# Requires internet access to download packages and source code.
# Usage: bash mount-mac-apfs.sh
# Optional APFS volume index: bash mount-mac-apfs.sh 1
# The default volume index is 0. A separate Data volume may hold user files.
# Source and limitations: https://github.com/sgan81/apfs-fuse
# This driver is read-only and experimental; some compression is unsupported.
# Enter FileVault passwords only at the driver's terminal prompt, never here
# or in a public Gist. Copy recovered files onto a separate external drive.
