An Etrade Mac app: keeping the trading screen out of a browser tab

Searching for an Etrade Mac app usually ends in a loop. The platforms page names a downloadable desktop platform, so an installer clearly exists. The download link asks for a log in before it will say anything about system requirements. The Mac App Store returns nothing published by E*TRADE at all. Meanwhile the trading screen sits in a browser tab, one stray keystroke away from closing itself in the middle of an open order.

This article covers what E*TRADE actually ships for each surface, what the Pro download does and does not promise, and what to do about the web platform, which is where a Mac user ends up whether or not that was the plan.

What E*TRADE publishes, surface by surface

The platforms page lists five products, and reading them as five separate things rather than one product with five skins makes the Mac question much easier to answer.

Power ETRADE Pro is described as "the ultimate in downloadable desktop trading with nearly unlimited customization, highly advanced charting, and complex trading". Power ETRADE Web is described as the web-based platform "with no download required". Power ETRADE App and ETRADE App are the two mobile applications. E*TRADE Web is the older, investor-facing site. The page describes the Power family as "synced across desktop, web and mobile", which is the honest framing: it is one account seen through several front ends, not one application ported to several systems.

On the App Store side, both mobile applications are published by ETRADE Securities and both are free. Power ETRADE-Advanced Trading is filed under Finance, weighs 127.7 MB, requires iOS 17.0, lists iPhone and iPad as its devices, and carries 13,000 ratings at 4.5. E*TRADE: Invest. Trade. Save. weighs 133.3 MB, requires iOS 17.5, lists iPhone, iPad and Apple Watch, and carries 381,000 ratings at 4.7. Its listing states $0 commissions for online U.S.-listed stock, ETF, mutual fund and options trades, with other fees possibly applying.

A search of the Mac App Store catalogue for the same publisher returns no Mac application. That is the first half of the answer: there is no App Store route to a Mac build.

The Pro download, and why its requirements are not public

The Pro page is where most searches stop, because the call to action is not a download button.

The public page describes the platform in detail and says nothing about which operating systems it runs on. It names multi-monitor support, up to 120 tools and charts across six configurable workspaces, the ability to move tool windows outside the platform frame, window linking so that a symbol change propagates across panels, 16 chart types, more than 120 technical studies, more than 30 drawing tools, Level II market depth, and streaming real-time quotes and news. What it does not do is publish a system requirements table, because the installer and its requirements sit behind account authentication.

The practical consequence is worth stating plainly rather than guessing around. Anyone who already has an account can log in and read the requirements directly, and that is the only reliable source. Anyone who does not have an account yet cannot find out in advance from the public site, and planning a Mac workflow around an installer whose requirements cannot be checked is a poor bet. The reliable surface on a Mac is the web platform, and it is worth setting that up properly whether or not Pro turns out to be an option later.

The web platform is the Mac platform

Power E*TRADE Web is not a fallback. The platforms page claims a rating of #1 Web Trading Platform for 14 years in a row from StockBrokers.com, and the feature list is close enough to the desktop platform that the gap matters mostly to people running four monitors.

The web platform's own page names 145 or more chart studies and drawing tools with saved setups and trading directly from the chart, technical pattern recognition that draws support and resistance lines automatically, an earnings move analyser, risk and reward probabilities through snapshot analysis, custom and preset scans through Live Action, an exit plan tool for setting a profit target and stop loss in one step, and paper trading for testing without committing money. Paper trading is available on both the web platform and the Power E*TRADE app.

So the realistic Mac setup is a browser window, and the interesting question becomes which browser window. That is not a small question for a trading screen, because the failure modes of a tab are specific and expensive.

What a browser tab costs a trading screen

The first cost is the close key. A positions page living in the same window as research tabs, a broker comparison, and three news articles is one Command W away from vanishing. On a page that carries an unsaved order ticket or a configured chart layout, that keystroke is not a minor inconvenience.

The second is the back button. Multi-step flows on brokerage sites are built on the assumption that navigation happens through the page, not through the browser chrome, and a back press in the middle of an order or a transfer can put the session into a state the page did not plan for. A window whose navigation controls are hidden removes the temptation entirely.

The third is session handling. Brokerage sessions time out aggressively and deliberately. A tab buried behind eleven others is a tab whose session has quietly expired, which turns a fast look at a position into a log in, a second factor, and a re-selected time range. A window that is visibly its own thing gets touched often enough that this happens less.

The fourth is separation of accounts. A personal brokerage account and a joint or business account are two sessions on one domain. Browsers handle that with profiles, which works and is tedious. Two separate application windows, each with its own cookie store, is the same outcome without the profile switching.

The two free routes on macOS, and where each stops

Both built in routes cost nothing and take about a minute, and they stop in different places.

Safari's route arrived with macOS Sonoma 14. Open the page, choose File then Add to Dock, type a name, and the result lands in the Applications folder inside the home folder, reachable from the Dock and from Spotlight.

A web app functions independently of Safari. It shares no browsing history, cookies, website data, or settings with Safari. In this way, it keeps your browsing separate, similar to using a Safari profile. What you do in a web app stays in the web app. Source: support.apple.com

Apple's page also documents the settings that matter here. The navigation controls, meaning the back and forward buttons, can be switched off. The name and icon are editable. Notification permission granted inside the web app, rather than in Safari, is what enables the unread badge on the Dock icon.

The Chromium route works on systems older than Sonoma and on machines where Safari is not the browser of record. Installing a page as a standalone window is supported by Chrome and Edge on macOS, Windows, Linux and ChromeOS, the installed window runs in standalone or minimal-ui display mode, and the result shows up in Launchpad, Spotlight and the application switcher like anything else.

	Safari, Add to Dock	Chrome or Edge, install	A dedicated tool
macOS requirement	Sonoma 14 or later	works on older systems	macOS 12 or later
Engine	WebKit only	Chromium only	seven Chromium builds, selectable
Hide back and forward buttons	yes	display mode dependent	yes
Separate cookies from the browser	yes	yes	yes, one profile per app
Two windows, two logins, same site	no	no, one install per browser	yes
Cost	free	free	three apps free, then one payment

The row that settles most cases is the second from the bottom. Neither free route produces two windows for the same address, because each browser treats a second install of the same URL as the same application. For a single account that never matters. For anyone running a personal account alongside a joint account, or a taxable account alongside a retirement account in a separate log in, it matters on the first day.

Which screens earn a window, and which do not

The test is whether the page stays open or gets opened, read and closed.

The trading platform itself passes clearly. It is the page that stays up through the session, it is the page whose layout takes effort to configure, and it is the page where an accidental close costs the most. A watchlist or a single chart used as a market monitor passes too, particularly on a second display where the window can be assigned to its own desktop space and left alone.

Statements, tax documents and the transfer flow generally fail. Those are errands. They are opened once, finished and closed, and a tab strip is the right shape for that kind of work. Forcing them into a dedicated window adds an icon to the Dock that gets used four times a year, and a Dock full of icons that are rarely used is slower to read than a Dock with three that are used constantly.

Research reading sits in between, and the deciding factor is usually the second display. A news and screener window parked on a side monitor alongside the trading platform behaves like a dashboard and earns its icon. The same pages opened occasionally on a single laptop screen do not, because every switch to them hides the thing that actually needs watching.

Where the count of windows worth keeping goes past two or three, building each one by hand starts to cost more than it saves. Choosing the service from a prepared list rather than typing a URL, a name and hunting for an icon is the practical difference, and the Supported services catalogue also reads as a rough census of which browser-based tools other people decided were worth pulling out of the tab strip. After that, the two settings that decide whether the window stays usable are the engine and the handling of external links, both covered under Features. A brokerage page is full of links to research providers, prospectuses and help articles, and whether those open inside the trading window or hand off to the default browser is the difference between a window that stays a trading screen and one that becomes a browser again within a week.

What to change first

Give the Power E*TRADE Web platform a window of its own with Safari's Add to Dock, and switch the navigation controls off in its settings so the back button cannot be reached. Run it for a week before deciding anything else. If a second window for a second log in turns out to be necessary, neither free route can supply it, and Kagemusha builds each window from a preset rather than by hand.
