Define the JNA library path for macOS

JNA_LIB_PATH="/usr/local/lib/jna"

Check if JNA library path exists

if [ ! -d "$JNA_LIB_PATH" ]; then log_message "JNA library path not found: $JNA_LIB_PATH" log_message "Please install JNA for macOS using Homebrew: brew install jna" exit 1 fi

Locate Autopsy's configuration file

AUTOPSY_CONF_DIR="${HOME}/autopsy-4.21.0" AUTOPSY_CONF_FILE="${AUTOPSY_CONF_DIR}/etc/autopsy.conf"

if [ ! -f "$AUTOPSY_CONF_FILE" ]; then log_message "Autopsy configuration file not found: $AUTOPSY_CONF_FILE" log_message "Ensure that Autopsy is correctly installed and configured." exit 1 fi

Backup the existing configuration file

BACKUP_CONF_FILE="${AUTOPSY_CONF_FILE}.bak.$(date '+%Y%m%d%H%M%S')" cp "$AUTOPSY_CONF_FILE" "$BACKUP_CONF_FILE" log_message "Backup created for the configuration file: $BACKUP_CONF_FILE"

Add the JNA library path to the configuration file

if grep -q "jna.library.path" "$AUTOPSY_CONF_FILE"; then sed -i '' "s|jna.library.path=.*|jna.library.path=${JNA_LIB_PATH}|" "$AUTOPSY_CONF_FILE" log_message "Updated JNA library path in the configuration file." else echo "jna.library.path=${JNA_LIB_PATH}" >> "$AUTOPSY_CONF_FILE" log_message "Added JNA library path to the configuration file." fi

log_message "JNA library path successfully configured for Autopsy." log_message "Script execution completed successfully." exit 0
