Google Maps desktop: a map window you can leave open all day

The search for Google Maps desktop almost never comes from someone who has never used Maps. It comes from someone who uses it constantly on a computer, for route planning, for checking addresses against a spreadsheet, for measuring a site, for building a map of client locations, and who has noticed that the tool is living in a browser tab that keeps getting buried. There is no Google Maps application to download for a Mac. The computer version is the website, and the whole question is what kind of window that website deserves.

Google's own phrasing gives away the answer

The getting started page in the Maps help centre describes the two ways to reach the product, and the wording is precise.

App on a phone. Maps on a computer. Every help article in that centre carries tabs labelled Computer, Android, iPhone and iPad, and the Computer tab always describes a browser. There is no installer, no disk image, no Mac App Store listing from Google.

That is a fact worth settling early, because a good share of the download pages that appear for this search are third party bundles wrapping the website, and a few are unrelated software that shares part of the name. Knowing that the official route is a browser saves the effort of hunting for one that does not exist.

What the computer version does better than the phone

A surprising amount, and it explains why people keep Maps open on a laptop rather than reaching for a phone.

Directions on a computer show several routes at once, with the recommended one in blue and the alternatives in grey, each labelled with its estimated travel time. Google's directions page lists driving, public transit, walking, ride sharing, cycling, flight and motorcycle as the available modes on a computer. Comparing three routes and picking one is a large screen job, and it is genuinely awkward on a phone.

Measuring is a computer only feature. Right clicking a starting point offers Measure distance, and clicking along the map builds a path with a running total in miles and kilometres. That is how people check the walk between two buildings, the length of a fence line or the frontage of a plot without leaving the map. Google attaches a warning to it that turns out to matter.

Looking a place up is also a better experience on a computer once the screen is wide. Google's getting started page lists what a place card carries once it is selected: directions to it, information such as business hours and menus, and Street View imagery. On a laptop all of that can sit beside the map instead of covering it, which is why anyone checking a list of addresses against reality works faster on a computer than on a phone. The same page notes that a Google Account can hold home and work addresses so that routes from them are one click rather than two fields of typing, which only pays off for someone who plans routes often.

My Maps is the other computer anchored piece. It is a separate browser tool for building custom maps with layers, imported spreadsheets of addresses and shareable links, and Google states that it is used by signing in with a Google Account and that it works best in Chrome, Firefox or Safari. Anyone maintaining a map of delivery zones, client sites or survey points is spending real hours in it, and it has no phone equivalent for authoring.

What the computer version cannot do

Two gaps, and both are permanent rather than oversights.

Offline maps do not exist on a computer. Google's documentation on the feature describes saving an area from Google Maps to a mobile device or tablet for use when offline, and every instruction on the page starts with opening the app on a phone. A browser window with no connection shows nothing useful, and no wrapper changes that.

Live turn by turn navigation is a phone feature too. A computer can produce the route, and the route can then be followed on a phone, but the moving blue arrow belongs to the mobile app.

Neither gap is an argument against a desktop window. They simply mark the boundary: planning, measuring, authoring and looking things up on a computer, navigating and offline use on a phone.

The browser engine decides what the map looks like

This is the technical point that should drive the choice of route, and it is the one almost no article about Google Maps on a desktop mentions.

Maps on a computer has more than one rendering mode. Google documents a default view, a satellite view, a 3D mode with globe view, smooth zooming, 3D buildings and satellite imagery, and a 2D mode described in blunt terms.

2D Mode: This Google Maps version may work better on older or lower performance computers. It doesn't have 3D images or WebGL, and it uses simple zooming and transitions. Source: support.google.com

The same page states that a computer meeting the system requirements can still miss the full 3D version because of the browser, since some browsers block the WebGL technology that produces 3D images. Lite mode, the one that disables distance measuring, is the visible symptom of landing in a reduced rendering path.

For anyone about to put Maps into a window of its own, the consequence is simple and testable. A window is only as capable as the engine behind it. A route built on Chrome or another Chromium engine gets Chrome's WebGL behaviour. A route built on Safari gets Safari's. Before committing, open the globe view and try to measure a distance. If the lightning bolt appears, the engine is the reason, not the window.

The routes, side by side

Route	Setup	Own Dock icon	Rendering engine	Separate Google login
Browser tab	None	No	Whichever browser is in use	Shares the browser session
Safari, Add to Dock	Two clicks in Safari	Yes	Safari and WebKit	Own cookie store
Chrome, Install page as app	Two clicks in Chrome	Yes	Chrome and Chromium	Shares the Chrome profile it came from
Site to app tool	Pick a preset or paste the URL	Yes	A Chromium engine of choice	Own profile per app

Apple documents the Safari route in the Safari User Guide, and the description matches what a map needs.

Apple's settings pages for web apps add two useful controls. General settings allow changing the name, the URL the app opens, the icon and whether navigation controls appear in the toolbar. Privacy settings control location access for that one app, which is exactly the permission Maps asks for, granted to the map window rather than to an entire browser.

Chrome's equivalent lives under the three dot menu, in Cast, save, and share, then Install page as app. The app inherits the Chrome profile it was created in, and Chrome has to be running underneath it.

What a dedicated window fixes for a map

Four things, each small and each repeated many times a day.

Screen area. A map rewards every pixel. Removing the tab strip, the bookmarks bar and the address bar gives that space back to the map, and Apple's web app settings allow turning the remaining navigation controls off as well.

Retrieval. Command+Tab reaches a map window. Finding a Maps tab among twenty others does not have a keyboard shortcut. For work that alternates between a map and a spreadsheet every few minutes, this is the difference that gets noticed first.

Accidental loss. Command+W in a tab strip throws away whatever was on screen, including a half built measurement path or a set of directions with waypoints. A window that reopens to the same place is more forgiving of a mistyped shortcut.

Location permission scoped to one thing. Maps works better when it knows where the machine is. Granting that to a single map application rather than to a browser holding thirty sites is a smaller grant for the same benefit.

There is a fifth benefit that only shows up after a week. A map application can be added to the login items in System Settings, so it is already open and already positioned when the machine finishes starting. For work that begins with a map every morning, that removes a small ritual entirely: no tab to reopen, no address to retype, no waiting for the globe to load while a call starts. A browser tab cannot be restored that reliably, because reopening a browser restores a whole session rather than one page in one place.

What a window does not fix is the rendering mode, and it does not create offline access. Being clear about the split prevents the disappointment of setting up a beautiful icon and finding the same lightning bolt underneath.

Two accounts, and who owns the custom map

One more reason people end up wanting a separate window has nothing to do with the map itself.

Custom maps in My Maps belong to the Google account that created them, and saved places, lists and starred locations belong to the signed in account too. On a machine that carries both a personal and a work Google login, the result is predictable: a map built at work is invisible in the personal session, and the wrong set of saved restaurants appears during a client call.

A browser handles this with profiles, one per identity, each a separate window to manage. A single application with its own cookie store handles it by existing: the map app opens the account it was signed into, and the browser's own session stays untouched. A tool that turns a website into a standalone Mac app assigns each app its own browser profile for exactly this reason, so a work map and a personal map can be two icons rather than a sign out. The Features page describes how the isolation works, and the Supported services page lists the sites already prepared as presets.

There is a version of this that catches people out. Someone who builds a custom map while signed into a personal account, then shares the link with colleagues, has made a map owned by an account that leaves when they do. Deciding which account owns the map before building it is worth thirty seconds, and a dedicated window makes that decision visible instead of accidental.

What to change first

Open the globe view and try Measure distance in whichever browser is in use. If both work, give Maps its own window with Safari's Add to Dock and grant location access to that one app. If the map ends up in Lite mode, or if a work Google account and a personal one keep colliding, set the map up as its own application on a Chromium engine with Kagemusha and keep the browser out of it.
