Bash Script - Mac
Ensure the script has execute permissions by using the following terminal command:
chmod +x /path/to/script.sh

Mac:

#!/bin/bash

# Check if the machine is a MacBook (laptop)
MODEL_IDENTIFIER=$(system_profiler SPHardwareDataType | awk '/Model Identifier/ {print $3}')
if [[ ! "$MODEL_IDENTIFIER" =~ "MacBook" ]]; then
echo "This script is intended for MacBook models only."
exit 1

To handle cases where the initial script does not work for certain Mac models, you can use the alternative script with adjustments below:

Note: When running the alternative MacOS script through an RMM or system-level deployment tool, the $HOME variable may not always be properly set. If this happens, the download path may resolve to /Downloads/TimusConnect.pkg, which is not writable on macOS and may cause the download to fail with a Failure writing output to destination error. If this issue occurs, update the destination path in the script to use a writable system location such as /tmp/TimusConnect.pkg.

Example:
Change:
DESTINATION="$HOME/Downloads/TimusConnect.pkg"
To:
DESTINATION="/tmp/TimusConnect.pkg"

MacOS:

#!/bin/bash

# Define variables
DOWNLOAD_URL="https://repo.timuscloud.com/connect/Timus-Connect.pkg"
DESTINATION="$HOME/Downloads/TimusConnect.pkg"
LOG_FILE="/tmp/timus_install.log"

# Ensure the log file is writable
if [[ ! -w $(dirname "$LOG_FILE") ]]; then
    echo "Error: Cannot write to log file at $LOG_FILE. Check permissions or use a different path."
    exit 1
fi

# Redirect script output to log file
exec > >(tee -a "$LOG_FILE") 2>&1
echo "Starting Timus Connect installation: $(date)"

# Ensure the Downloads directory exists
mkdir -p "$HOME/Downloads"

# Download the package
echo "Downloading the package from $DOWNLOAD_URL..."
curl -L -o "$DESTINATION" "$DOWNLOAD_URL"

if [[ $? -ne 0 ]]; then
    echo "Error: Failed to download the package from $DOWNLOAD_URL. Exiting."
    exit 1
fi
echo "Download completed: $DESTINATION"

# Install the package silently
echo "Installing the package..."
sudo installer -pkg "$DESTINATION" -target /

if [[ $? -ne 0 ]]; then
    echo "Error: Installation failed. Exiting."
    exit 1
fi
echo "Installation completed successfully."

# Optional cleanup
echo "Cleaning up downloaded file..."
rm -f "$DESTINATION"
echo "Cleaned up downloaded file: $DESTINATION"

echo "Timus Connect installation completed successfully: $(date)"
exit 0
