macOS Sequoia quietly fixes annoyances accumulated over years. Window snapping finally works like Windows, iPhone mirroring is useful on a single desk, and Safari gained meaningful quality-of-life updates — if you know where to look.
New features worth using
- Window tiling — drag to edges or use green button menu for zones.
- iPhone mirroring — control phone from Mac; notifications without picking up device.
- Safari Highlights — key info extracted on pages; disable if cluttered.
- Presenter Preview — see upcoming slide before audience during share.
- Passwords app — centralised credentials; still use Bitwarden if cross-platform.
- Calendar + Reminders integration — tighter than before for GTD workflows.
Power user classics
Hot Corners — System Settings → Desktop & Dock. Spotlight as launcher (Cmd + Space). Quick Look (select file, Space). Screenshot toolbar (Cmd + Shift + 5). Stage Manager if you like iPad-style window grouping — many disable it; try before judging.
Performance on older Macs
Reduce transparency and motion in Accessibility. Limit Login Items in General → Login Items. Store Desktop and Documents in iCloud only if you understand sync conflicts on large video projects. Clear old iOS backups if disk full.
Safari vs Chrome
Safari wins battery life on MacBooks significantly. Chrome wins extension ecosystem. Pick one primary — running both full-time doubles RAM use for browser profiles.
