Best Apps to Install on a New Mac in 2026: The Essential Setup Guide
Just got a new Mac? Here are the first apps to install: browsers, utilities, Dock organizer, password manager, and everything else you need on day one.
A fresh Mac is a chance to reset habits—before the Downloads folder becomes a graveyard. Install in an order that secures accounts first, then fixes window ergonomics, then adds communication and creative stacks. Below is a day-one checklist you can adapt for work, school, or personal machines.
Quick picks: Browser (Arc or Chrome), password manager (1Password or Bitwarden), Otterdock for immediate Dock organization, Rectangle for window snapping, cloud storage (iCloud or your team’s provider), then messaging (Slack, Discord, Messages). Tune energy and backup before you migrate heavy projects.
Step 1: Browser (Arc or Chrome)
Install your primary browser first—you will need it for downloads, OAuth logins, and password manager setup. Arc from The Browser Company emphasizes spaces and vertical tabs;Chrome remains the compatibility default for extensions and enterprise policies. Both are free; pick based on whether you value Arc’s workspace model or Chrome’s ubiquity. Sign in only after you trust the network; enable sync deliberately.
Step 2: Password manager (1Password or Bitwarden)
Before you reuse passwords across new installs, add a password manager. 1Password is a polished paid option with family and team plans—see 1password.com. Bitwarden offers a free tier and open-source clients—see bitwarden.com. Turn on two-factor tokens here once you migrate logins; it beats SMS wherever supported.
Step 3: Otterdock (Dock organization)
Early is the best time to organize the Dock: group “Work,” “Personal,” “Dev,” or “School” before icons accumulate. Otterdock adds expandable groups for apps, files, folders, and links; click or hover interaction; local data; skins; macOS 14+. Free tier includes two groups; Pro is $6.99 direct with a Mac App Store release planned at $2.99. We build Otterdock—if you prefer zero third-party tools, start with native Dock folders and revisit when you need mixed item types or hover popups.
Step 4: Rectangle (window management)
macOS window tiling is limited compared to some Linux desktops. Rectangle adds keyboard-driven snapping and halves/quarters of the screen; there is a free open-source edition and a Pro line. We compare similar tools in our best macOS window management apps roundup—see rectangleapp.com. Install early so every meeting app and browser inherits the same muscle memory.
Step 5: Cloud storage
Choose one source of truth: iCloud Drive, Dropbox, Google Drive, or OneDrive—match what your team or school mandates. Enable selective sync so large folders do not saturate a small SSD on day one. Pricing varies—see each vendor’s site.
Step 6: Messaging
Install Slack, Discord, Microsoft Teams, Zoom, or WhatsApp as needed—after passwords and backups are stable. Messaging apps love to hijack notifications; set Focus modes and per-app alerts before they train you to context-switch all day.
| App / category | Role | Cost snapshot |
|---|---|---|
| Arc / Chrome | Browsing, downloads, SSO | Free |
| 1Password / Bitwarden | Passwords and 2FA | Paid (1Password); free tier (Bitwarden)—see website |
| Otterdock | Dock groups for apps and assets | $6.99 direct; 2 free groups; MAS planned $2.99 |
| Rectangle | Window snapping | Free OSS; Pro—see website |
| iCloud / Dropbox / etc. | File sync | See vendor pricing |
| Slack / Discord / etc. | Team chat | Free tiers; paid—see website |
Finish with Apple’s Software Update, FileVault if you want full-disk encryption, and Time Machine or an equivalent backup target. A clean Dock policy—native folders or Otterdock groups—costs minutes now and saves hours later when you switch contexts daily. Once you are settled, explore the best free macOS apps to round out your toolkit.
