A Discovery Plus desktop app: shows in a separate window

Searching for a discovery plus desktop app on a Mac ends in the same place every time: the Mac App Store has nothing from Warner Bros. Discovery, the site offers no installer, and the Help pages point back to a browser. That is not an oversight and it is not going to change with a software update. It is the shape of the product.

Which leaves a real question underneath the one that got typed into the search box. If the service is only ever going to be a website on a Mac, what can be done about the fact that a website is a bad place to watch television? The honest answer has two halves: one thing the service will never do on a desktop, and one thing that can be fixed in about thirty seconds.

What the service officially supports

The device list on discoveryplus.com is worth reading closely, because it is the definitive answer to the installer question. The service describes itself as available for most smartphones, tablets and desktop browsers, and most connected devices, then names them: Amazon Fire TV streaming devices and Fire TV Edition smart TVs; Apple iPads, iPhones, iPod touches and Apple TVs; Android phones and tablets, Chromecast with Google TV and Chromecast built in devices; Xbox One and Series S and X; the Roku platform; Samsung and VIZIO smart TVs from 2017 and newer; and LG smart TVs from 2018 and newer.

Two things are absent from that list. There is no macOS application and no Windows application. The phrase covering every computer is desktop browsers, and that is the whole of the desktop story. Every platform that gets a native app on that list is a phone, a tablet, a television or a games console.

The reason is structural rather than technical. Native apps exist on the platforms where a store is the only way in, or where a remote control needs a ten foot interface. A Mac already has a browser that plays protected video, so building and maintaining a separate desktop client buys the service almost nothing. Netflix made the same call. So did HBO Max on the Mac.

It follows that any listing found elsewhere claiming to be a desktop version of the service is worth checking against that official device list before installing it. The list above is what the service commits to supporting.

What the plans include, and what they do not

The two plans are straightforward, and one line in them decides the entire offline question.

	discovery+	discovery+ (Ad-Free)
Price	$5.99 per month	$9.99 per month
Free trial	7 days for new subscribers	7 days for new subscribers
Simultaneous streams	4 devices	4 devices
Resolution	Full HD	Full HD
Downloads	Not included	100 downloads

The ad supported plan runs at $5.99 per month with limited ads, the ad free plan at $9.99. Both allow streaming on 4 devices at once and both top out at Full HD video resolution. A subscription covers more than 70,000 episodes, with individual profiles and parental controls for filtering mature content.

The downloads row is the one that matters for anyone hoping a desktop app would enable offline viewing. The service states that ad free subscribers can download episodes to watch offline on iOS and Android mobile devices. Downloads are a phone and tablet feature. There is no route to an offline copy on a Mac, with or without a window of its own, and no third party wrapper changes that, because the capability is not in the desktop product at all.

For a flight or a commute, the plan is a phone or an iPad, and the 100 download allowance on the ad free plan is the number to work with. Anyone who assumed a desktop app was the missing piece for offline viewing can stop looking now, which is worth knowing before spending an evening on it.

What a browser tab costs when it is a television

Everything else in the experience is a window problem, and window problems are fixable. They are also easy to underrate until listed out.

The tab drifts. A show that runs for forty minutes shares a tab strip with work, and the tab ends up narrow and unlabelled somewhere to the right. Finding it again means hunting by favicon.

Command and W is one key away from Command and Q and both are destructive in a browser. Closing the wrong tab mid episode means reloading, waiting through the player initialising and scrubbing back to a position the site may or may not have saved.

Notifications and sound belong to the browser, not to the show. A Focus rule aimed at the browser silences work notifications and the episode together, or silences neither. There is no way to treat the two differently while they are the same application.

Sleep and window behaviour are also the browser's. A full screen tab is a full screen browser window, which competes with everything else the browser is doing, including a background tab that decides to autoplay something.

None of this is a complaint about the streaming service. It is the ordinary cost of a long lived, full screen, audio playing website sharing a window with twenty other things.

Giving it a window of its own

macOS has two routes built in, and a third for the cases the first two do not cover.

In Safari, open the site, click the share control in the toolbar and choose Add to Dock. The result is an icon in the Dock and in Spotlight, a simplified toolbar with no tab strip or address bar, an existing sign in that carries over, and an app that can post notifications on its own.

In Chrome, the equivalent is in the three dot menu under Cast, save and share, as Install page as app. Google's help pages cover finding and removing installed web apps afterwards.

The third route is a site to app tool, which wraps a chosen browser rather than relying on whichever one is built in. That distinction matters for streaming specifically. Protected video plays according to the browser doing the playing, so a wrapper built on a Chromium based browser behaves exactly as that browser does on the same site, including any extensions allowed to run inside it. Per app profiles are the other reason people end up here: a household with two accounts, or one person keeping a work browser and a personal one apart, gets two separate signed in apps instead of one browser fighting over cookies. The Features page covers which parts of the window can be turned on and off per app, and the Supported services list shows which sites already have presets.

	Browser tab	Window of its own
Finding it again	Scan the tab strip	Dock icon, Command and Tab
Command and W	Closes the episode	Closes the app
Screen used by interface	Tab strip plus address bar	Simplified toolbar
Focus rules	Apply to the whole browser	Apply to this app
Resolution and downloads	Set by the plan	Set by the plan, unchanged

Profiles, households and one app each

The service supports individual profiles and parental controls that filter out mature content, and both features are built for a household rather than a person. They work in a browser, but they work badly in a browser shared by several people, because the browser remembers one session at a time and switching profiles inside the site is a manual step somebody will forget.

An app per account changes the arithmetic. Two apps, two isolated profiles, two permanently signed in sessions, each with its own icon and its own name. Nobody switches anything. A child's app opens on a profile that already has the content filter applied, and there is no path from that window to an adult profile without opening a different app. Compared with trusting everyone to check which profile is active before pressing play, this is a meaningful improvement in a shared machine.

The same isolation solves a smaller and more common problem: a Mac used for work with a browser signed into a work Google account, where a streaming site keeps inheriting the wrong identity or the wrong ad personalisation. Separate profiles mean the streaming app has no connection to the work browser's cookies at all.

There is a cost to name. Isolated profiles mean the app starts with no session, so the first launch asks for a sign in. That happens once. It also means the browser's saved passwords are not available inside that window unless a password manager extension is running there, which is exactly the case where a Chromium based wrapper matters more than the Safari route, since Safari web apps do not load extensions.

For a single person on a single Mac none of this applies, and the simplest route is the right one. For a shared machine it is the whole argument.

What a separate window will not fix

The last row of that table is the honest limit, and it is worth stating plainly rather than leaving as a footnote.

Resolution is a plan property. Both plans are described as Full HD, so no window arrangement produces a higher resolution stream. Downloads are a mobile feature, so no window arrangement produces an offline copy on a Mac. Simultaneous streams are capped at 4 devices by the subscription, and separate app windows on the same Mac are still separate streams against that limit if they are playing at once.

Region is a plan property too. The United States version is available to subscribers in the US, including American Samoa, Guam, the Northern Mariana Islands, Puerto Rico and the US Virgin Islands. The service also operates in Brazil, Canada, Denmark, Finland, India, Ireland, Italy, the Netherlands, Norway, the Philippines, Poland, Spain, Sweden, the United Arab Emirates and the United Kingdom, with different catalogues. A local app window does not travel across those boundaries.

What the window does change is the part that was actually annoying: the show has an address, the wrong keystroke stops being destructive, the Dock gains an icon that looks like a television service instead of a browser, and a Focus schedule can treat viewing and work as two different things. That is a small change with a disproportionate effect on a forty minute episode.

What to change first

Make one app for the streaming service and leave the browser out of it, then judge after an evening whether the show still gets lost. If the household has two accounts, or a password manager extension needs to load inside the window, that is the case for a tool such as Kagemusha over the built in Safari route, and the Pricing page covers what the unlimited tier costs.
