Just in case anyone needs this I wanted to post it for an updated resource.
#!/bin/bash
# Script Name: Disable Slack updates.sh
# Author: [Michael Cleveland]
# Created On: [Creation Date, e.g., 2023-10-31]
# Last Modified By: [Michael Cleveland]
# Last Modified On: [2023-10-31]
# Version: 1.0
# Description:
# This script modifies the Slack application's preferences for the currently logged-in user on macOS.
# It specifically sets the 'SlackNoAutoUpdates' key to 'true', which prevents the Slack app from auto-updating.
# Usage:
# Ensure that Slack is not running or is restarted after this script runs to apply the changes.
# Note:
# This script uses PlistBuddy for editing plist files, as it ensures the file's integrity.
# Be cautious when editing plist files and always ensure backups are made before script execution.
# [Here starts the actual script code]
echo "Starting the update of Slack preferences..."
# Get the current logged-in user
USER=$(stat -f %Su /dev/console)
# Path to the .plist file
plist_file="/Users/$USER/Library/Preferences/com.tinyspeck.slackmacgap.plist"
# Key and value to be added/checked
key="SlackNoAutoUpdates"
expected_value="true"
# Check if the key exists and has the expected value
current_value=$(/usr/libexec/PlistBuddy -c "Print :$key" "$plist_file" 2>/dev/null)
if [[ $? -eq 0 && "$current_value" == "$expected_value" ]]; then
echo "The key '$key' already exists with the value '$expected_value'. No changes needed."
else
# Check if the key exists regardless of its value
if [[ $? -eq 0 ]]; then
echo "The key '$key' exists but with a different value. Updating it to '$expected_value'."
/usr/libexec/PlistBuddy -c "Set :$key $expected_value" "$plist_file"
else
echo "The key '$key' does not exist. Adding it with the value '$expected_value'."
/usr/libexec/PlistBuddy -c "Add :$key bool $expected_value" "$plist_file"
