How to Set Up a New Mac from Scratch

Step by step

1. 5 min

   Complete the initial macOS setup

   Power on your Mac and follow the Setup Assistant. Choose your region and language, connect to Wi-Fi, and either sign in with your Apple ID or create a new one. Enable Location Services and set up Siri if desired. Create your user account with a strong password.

   Note: Use a different password for your user account than your Apple ID for better security separation.

   Configure system preferences

   Open System Preferences and adjust key settings. In Security & Privacy, enable FileVault disk encryption and set a firmware password. In Trackpad, enable tap to click and configure gesture preferences. In Displays, adjust resolution and brightness to your preference.

   Note: Enable "Require password immediately after sleep" in Security & Privacy for maximum protection.

   Set up iCloud and data sync

   Go to System Preferences > Apple ID and configure iCloud services. Enable iCloud Drive, Photos, Contacts, Calendars, and Keychain based on your needs. If migrating from another Mac, use Migration Assistant in Applications > Utilities to transfer data.

   Note: Disable iCloud for apps you don't want synced to avoid unnecessary storage usage and sync conflicts.

   Install essential software updates

   Open System Preferences > Software Update and install any available macOS updates. After restarting, check for additional updates. Install Xcode Command Line Tools by opening Terminal and running 'xcode-select --install' if you plan to do any development work.

   Note: Enable automatic updates for system files and security updates to stay protected without manual intervention.

   Configure the Dock and menu bar

   Right-click the Dock and select Dock Preferences. Remove unnecessary apps and resize the Dock to your preference. In System Preferences > Dock & Menu Bar, configure which menu bar items to show and hide the Dock automatically if desired.

   Note: Keep only your most-used apps in the Dock to maintain a clean workspace and faster app switching.

   Install essential applications

   Download and install your core productivity apps. Use the Mac App Store for verified apps or download directly from developers' websites. Install a browser like Chrome or Firefox, productivity apps like Microsoft Office or Google Workspace, and any development tools you need.

   Note: Use Homebrew package manager for developer tools by running '/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"' in Terminal.

   Set up backup and security

   Connect an external drive and set up Time Machine backup in System Preferences > Time Machine. Configure automatic backups to run hourly. Install and configure antivirus software if desired, though macOS includes built-in security features like XProtect.

   Note: Use a dedicated external drive for Time Machine that's at least twice the size of your Mac's internal storage for optimal backup retention.
