How to Master Safari on Mac and iPhone: Tabs, Profiles, and Privacy

I have two completely separate browsers open right now, and they’re both Safari. One holds my work — the email, the project tools, the logins for clients — and the other holds the rest of my life, the shopping and the recipes and the football. They don’t share history, they don’t share cookies, they don’t even share which sites I’m signed into, and switching between them takes one click. This is Profiles, it’s been built into Safari for a couple of years, and almost nobody I meet has turned it on. It’s the single best thing the browser does, and it’s hiding in plain sight.

Most people treat Safari as a thing that just is — the blue compass you tap to get to the internet. But it has quietly grown a set of features that solve the actual annoyances of modern browsing: the hundred-tab pile-up, the bleed between work and home, the trackers following you shop to shop. None of them cost anything, and a fifteen-minute setup changes how the whole thing feels.

Tab Groups: stop drowning

If you’ve ever had so many tabs open that each one is just a sliver with no title, Tab Groups are the cure. A Tab Group is a named, saved set of tabs — Holiday 2026, Kitchen Reno, Tax — that you can collapse, switch away from, and come back to days later with everything exactly where you left it.

On a Mac, open the sidebar and you’ll find your groups down the left; click the + to make a new one. On iPhone, tap the tabs button in the bottom-right, then the group name at the bottom to switch or create. The best part is that they sync, so a group you build researching a trip on your Mac at lunch is waiting on your iPhone on the train home. You can even share a Tab Group with someone and you’ll both see tabs appear live as either of you adds them — genuinely the nicest way to plan something together.

Profiles: the feature you should turn on today

Tab Groups tidy your tabs. Profiles separate your whole life. Each profile gets its own history, cookies, extensions, Tab Groups, and Favourites — so your work profile is signed into the work accounts and your personal one isn’t, and neither one’s browsing shows up in the other.

On a Mac, go to Safari → Settings → Profiles and create Work and Personal. A little coloured marker appears in the toolbar, and you switch with a click or open a new window straight into a chosen profile. On iPhone you set them up in Settings → Safari → Profiles and switch from the tab overview. The day I split mine, a low-grade background stress I hadn’t even named went away: work links stopped surfacing in personal searches, personal logins stopped bleeding into work, and “private browsing for the thing I don’t want in work history” stopped being a workaround. If you do one thing from this whole article, do this.

Extensions and a calmer page

Safari takes real extensions from the App Store, and the ones worth having are content blockers that strip ads and trackers, plus the odd password or read-later helper. Manage them in Safari → Settings → Extensions on a Mac, or Settings → Safari → Extensions on iPhone — yes, iPhone runs them too, just a smaller catalogue. On a Mac you can even enable an extension per profile, so your work browser stays lean while your personal one runs the ad blocker.

For reading, Reader is the underused gem. On a cluttered article, tap the page menu in the address bar and choose Show Reader, and the page collapses to just the words, in a font and background you pick, with the autoplaying video and the newsletter pop-up gone. You can set Safari to open Reader automatically for sites that always need it. It’s the difference between fighting a webpage and reading one.

The small touches that compound

A few smaller features earn their place once you know they’re there. Pin a tab — right-click it on a Mac, long-press on iPhone — and it shrinks to an icon that stays put in every window of that profile; I keep mail and calendar pinned and never lose them again. The Start Page, the screen behind every new tab, is yours to shape: scroll to the bottom of it, hit Edit, and switch on Favourites, your Reading List, the Privacy Report and a background image, or switch off the bits you find noisy. The Favourites row under the address bar is worth curating down to the eight or ten places you genuinely visit.

Then there’s continuity, which is the quiet Apple magic worth leaning on. Start reading something on your iPhone and your Mac shows a Handoff icon to pick up the very same page; open the tab overview and iCloud Tabs lists everything open on your other devices, so the article you abandoned on the Mac at home is one tap away on the train. None of these are headline features. All of them shave off a small daily friction, and small daily frictions are exactly the ones that wear you down without you noticing.

Privacy, which Safari does better than it brags about

This is where Safari quietly earns its keep. By default it runs Intelligent Tracking Prevention, which stops the trackers that follow you from one shop to the next. Tap the page menu and open the Privacy Report to see exactly which trackers it blocked and on which sites — it’s a sobering and oddly satisfying list.

Two more to know. Hide IP Address keeps trackers from using your address to fingerprint you. And if you pay for iCloud+, turn on Private Relay in your iCloud settings: it routes your browsing through two relays so neither Apple nor your internet provider can build a profile of where you go. It’s not a full VPN and Apple is careful not to call it one, but for everyday browsing it’s a real, free-with-iCloud+ privacy upgrade most subscribers never switch on.

And then there are passkeys. Safari, backed by your iCloud Keychain, lets you sign into supporting sites with Face ID or Touch ID and no password at all — and because a passkey only works on the genuine site, no fake login page can ever phish it out of you. Every site that offers one is a password you never have to remember and never have to worry about leaking.

One bonus row from that table worth calling out: web apps. A site you use like an app — your email, a planning tool, a calendar — can be lifted out of the tab clutter entirely. On a Mac, open the site and choose File → Add to Dock; on iPhone, use the share button and Add to Home Screen. It now opens in its own clean window with its own icon, no address bar, no tabs, behaving like a real app. I’ve done this with three tools I use daily and stopped losing them in a sea of tabs.

The thing I’d leave you with is that Safari rewards five minutes of setup more than almost any app on your devices, precisely because you use it more than almost any app on your devices. Split work and life into Profiles, build a couple of Tab Groups for the projects that sprawl, switch on Private Relay if you pay for iCloud+, and say yes to passkeys whenever a site offers. None of it is hard, all of it is free, and the browser you’ve been treating as a plain blue compass turns out to have been quietly waiting to do a great deal more.
