Initial System Configuration
Complete the macOS Setup Assistant
Choose your language, region, and sign in with your Apple ID. If migrating from another Mac, skip Migration Assistant for now and do a clean setup for better performance.
Set your preferred language and region
Connect to your WiFi network
Sign in with your Apple ID
Run all available macOS updates
Go to System Settings > General > Software Update. A fresh Mac often has 1-3 pending updates totaling 2-5 GB. Restart after each update cycle until no more appear.
Set your computer name and hostname
System Settings > General > About > Name. Pick something identifiable like 'Sarah-MacBook' rather than the default. This name shows up on AirDrop and local networks.
Enable FileVault disk encryption
System Settings > Privacy & Security > FileVault. Encryption adds virtually zero performance impact on Apple Silicon Macs. Store your recovery key in a secure location separate from the Mac itself.
Display and Input Preferences
Adjust display scaling and brightness
System Settings > Displays. The 'More Space' option gives you roughly 25% more screen real estate. Enable True Tone for automatic color temperature adjustment based on ambient light.
Configure trackpad gestures and sensitivity
System Settings > Trackpad. Enable tap to click, three-finger drag (under Accessibility > Pointer Control), and set tracking speed to at least 7 out of 10 for faster cursor movement.
Set up keyboard shortcuts and modifiers
System Settings > Keyboard > Keyboard Shortcuts. Remap Caps Lock to Escape or Control if you rarely use it. Set key repeat rate to fast and delay until repeat to short for quicker text editing.
Configure Dock size, position, and auto-hide
System Settings > Desktop & Dock. Set the Dock to auto-hide to reclaim 70-80 pixels of vertical screen space. Remove default apps you won't use by right-clicking and selecting Remove from Dock.
Security and Privacy Setup
Set up Touch ID with multiple fingerprints
System Settings > Touch ID & Password. Register 2-3 fingers including one from each hand. Re-scanning the same finger from different angles improves recognition accuracy by about 30%.
Configure the firewall and login settings
System Settings > Network > Firewall, turn it on. Then go to Lock Screen settings and set 'Require password after screen saver' to immediately or within 5 seconds.
Review app permission settings
System Settings > Privacy & Security. Check Location Services, Camera, Microphone, and Full Disk Access. Deny access for any app that doesn't clearly need it. Review this list monthly.
Enable Find My Mac
System Settings > Apple ID > iCloud > Find My Mac. This lets you locate, lock, or erase your Mac remotely if lost or stolen. Also enable 'Find My network' so it can be found even when offline.
Essential Applications
Install a web browser of your choice
Download directly from the browser's official website. If you used a different browser before, sign in to sync bookmarks, passwords, and extensions. Allow 10-15 minutes for a full sync of large bookmark libraries.
Set up a password manager
Install your password manager app and browser extension. Import existing passwords from your browser by exporting them as CSV first. A typical migration of 200+ passwords takes about 15 minutes.
Install productivity and communication apps
Start with your most-used 5-7 apps rather than installing everything at once. Check if apps are available natively for Apple Silicon — native versions use 30-40% less energy than translated ones.
Install email client or configure Mail app
Install messaging and video call apps
Install document editing and note-taking tools
Set up cloud storage sync
Install your preferred cloud storage app and choose selective sync to avoid filling your local drive. A 256 GB Mac should keep at least 40-50 GB free for system operations and caching.
Backup and Maintenance
Configure Time Machine backup
Connect an external drive with at least 2x your Mac's storage capacity. Time Machine runs hourly backups automatically. The first backup may take 1-3 hours depending on how much data you have.
Set up a secondary cloud backup
Time Machine covers local backup, but add a cloud backup for offsite protection. Most services back up continuously in the background using 1-5% of your bandwidth during initial upload.
Enable automatic macOS updates
System Settings > General > Software Update > Automatic Updates. Turn on all options including security responses. Critical security patches are typically under 500 MB and install in under 10 minutes.
Review and clean up storage
System Settings > General > Storage. Enable 'Empty Trash automatically' to clear files after 30 days. Review the storage breakdown — system data over 20 GB may indicate cached files worth clearing.
Frequently Asked Questions
How long does it take to fully set up a new Mac?
A thorough first-day setup takes 2-4 hours, including 30-60 minutes for macOS updates alone. If you are migrating data from an old Mac via cable, add another 1-3 hours depending on drive size. Plan a full afternoon or evening rather than trying to squeeze it into a lunch break.
Should I use Migration Assistant or start fresh on a new Mac?
A clean setup is faster and avoids carrying over years of junk files, old system extensions, and broken preferences. Migration Assistant works well for transferring user files, but it also copies over accumulated cruft that can slow down your new machine. The sweet spot: do a clean install, then manually move documents and photos via AirDrop or an external drive.
How much storage does macOS take up on a new Mac?
macOS Sequoia uses approximately 12-15 GB of disk space after a fresh install. With standard built-in apps like GarageBand, iMovie, and Xcode command line tools, total system usage climbs to 20-30 GB. On a 256 GB base model, that leaves roughly 220-230 GB for your files and applications.
Can I set up a new Mac without an Apple ID?
Yes, you can skip the Apple ID sign-in during setup and create a local-only account. However, you lose access to iCloud sync, the App Store, iMessage, FaceTime, and Find My Mac. Most people find it worth creating a free Apple ID even if they do not plan to buy anything from Apple.
What is the first app I should install on a new Mac?
A web browser you prefer (Chrome, Firefox, or Arc) is the practical first install since you will use it to download everything else. After that, prioritize a password manager so you can securely log into all your other accounts without reusing passwords or hunting through old emails for credentials.
