Installing a Mac is not just dropping apps into Applications. It is accounts, updates, permissions, backups, passwords, storage, and deciding what old clutter deserves to follow you. This page is built for the first real session with a new or freshly reset Mac.
How we organizeChoose the install route first, then move through the six-part spine: Prep, Update, Sign in, Install, Secure, Verify. Keep the old Mac or backup nearby until the final board is clean.
→ Choose your path
Start from the Mac on your desk.
A Mac install changes depending on whether it is brand new, restored, migrated, managed by work, or being rebuilt from scratch.
01Brand-new MacFresh machine, no old data required. Apple ID, Wi-Fi, macOS updates, apps, FileVault, and first backup.
02Moving from old MacMigration Assistant, Time Machine, iCloud, app cleanup, and the point where you stop copying old problems.
03Restoring from backupTime Machine, external drives, encrypted backups, and what to check before you trust the restore.
04Installing appsApp Store, downloaded installers, Homebrew, permissions, login items, and update habits.
05Work or school MacManaged profiles, company apps, VPN, browser certificates, screen recording permissions, and account boundaries.

Install

Verify

Install, answered.
The questions readers send during the first hour with a new Mac. Keep the old machine or backup nearby until the verification board is clean.
Q.01Should I use Migration Assistant or start fresh?+
Use Migration Assistant if the old Mac is healthy and organized. Start fresh if you want fewer stale apps, login items, and old settings.
Q.02Do I need Time Machine before setting up a new Mac?+
You need at least one trusted backup before migration, reset, or trade-in. Time Machine is the easiest local safety net.
Q.03Why will a downloaded Mac app not open?+
Gatekeeper may be blocking it, or the app may need updated permissions. Only override the warning when you trust the developer and source.
Q.04When should I turn on FileVault?+
Turn it on during first-day setup, after you know the account and recovery method are correct.
Q.05Can I erase the old Mac right away?+
Wait until files, apps, iCloud, passwords, photos, and a new backup have been verified on the new Mac.
Q.06What should I reinstall instead of migrating?+
Browsers, creative apps, developer tools, utilities, and anything that had old plugins or broken permissions are often cleaner reinstalled.
