System tower · floor
How to change default browser is not a complicated setting; it is a well-hidden one. All three documented routes live in the system’s own settings — not in the browser you are trying to switch to — and each system keeps it in a different place under a different name.
Then, under Set defaults for applications, choose the browser — and “next to Make [it] your default browser, select Set default.” Two clicks after you have found the right pane, and the pane is the hard part.
In macOS Ventura 13 and later it lives under Desktop & Dock, and you have to scroll down the pane to reach it. On earlier versions it was System Preferences › General.
Apple’s condition first: “To use Default Apps settings, update to the latest version of iOS or iPadOS.” Then a whole list of features, of which the browser is one.
The Mac one is worth a second look, because it moved. Apple’s instructions split at macOS Ventura 13: before it, the setting was in System Preferences under General, which is where you would expect it. From Ventura onwards it is in Desktop & Dock, which is where you would not, and it is far enough down that pane that you have to scroll. Any instruction written before that change sends you to the right idea in the wrong room.
Apple also puts the same first step at the top of both versions, and it is worth not skipping: install the other browser first. A browser that is not on the machine does not appear in the menu, and the menu is the only place the change happens.
Microsoft’s two ways of thinking about the same question, and the reason Windows feels harder
here than it should. The pane is not really asking which browser you prefer: it is a list of
file types and link types, each pointed at something, plus a shortcut for setting them from
the application’s side. That is why the search bar in that pane accepts things like
“Set a default for a file type or link type… Set defaults for
applications.”
.txt and protocol names rather than app names.
That structure is what to hold on to when something still opens in the wrong place after you thought you had settled it. Because Windows matches by type rather than by preference, the question to ask is not “which browser is my default” but “what is this particular type pointed at” — and the same pane answers it. Search it for the file extension or the protocol, and set that one by hand.
What else the iPhone list lets you hand over
The last line of that list is the useful one on any of the three systems. If the browser you want is installed and still does not appear as an option, Apple points you at the app’s developer rather than at your settings — which places the missing piece somewhere you cannot fix and saves you from looking for it where it is not.
A note on the setting sitting next to it, because it is genuinely strange. Changing the
default email app on a Mac is not done in System Settings at all. Apple’s instruction is
to open Mail, make sure it is set up with an account, and change the “Default email reader”
from inside Mail’s own settings. In other words: to stop using Apple’s mail app, you must first configure Apple’s mail app. Apple
says the account can be removed afterwards, and notes that some third-party apps “might offer a way
to set itself as the default” to avoid the whole dance.
A word on why any of this matters beyond preference. The default browser is what opens when something else on the machine hands you a link — a message, a document, a calendar invitation. Setting it is the difference between one browser that has your bookmarks, your extensions and your signed-in sessions, and two browsers that each have half of them. The second state is the one this setting exists to end.
The floors below take it four ways: the Windows pane and its two logics, the Mac setting that moved, the iPhone list and everything else on it, and what to do when the browser you want is not offered at all.
Four ways in.
One screen with two logics behind it — by application, or by file and link type. Knowing which one you are using explains the links that keep going elsewhere.
It moved at macOS Ventura, and instructions written before that are still the ones you will find first.
Since Apple opened this up, the browser is one entry among a dozen — and several of the others are worth knowing about.
The browser is installed, the pane is open, and the option is not there. Apple names the reason, and it is not on your machine.
It will not tell you to change this from inside the browser. All three documented routes are in the system’s settings, and that is the whole reason the setting is hard to find.
It will not treat a link that opens elsewhere as a bug. On Windows the association is per type, and the fix is in the same pane rather than in a reinstall.
And it will not recommend a browser. Which one you want is not a question this floor has any business answering; where the switch lives is. What holds instead is simple: the routes on all three systems, the two ways Windows assigns defaults, the macOS version split and the note about apps that offer no option are quoted from Microsoft’s and Apple’s own documentation, listed below.
