Perplexity in its own window, with notifications that work

Looking for the Perplexity Mac app in the Mac App Store turns up nothing from Perplexity AI Inc. The results are third party chat utilities from individual developers, plus assistants from other companies. That absence is not a sign the app does not exist. It exists, it is published by Perplexity, and it is downloaded straight from the company's own site. What has changed recently is what that download contains, because the macOS app is now the shell around an agent that operates the machine rather than a window onto a search box. That difference decides whether installing it is the right move.

The download lives on perplexity.ai, not in the store

Perplexity's Mac page carries a Download for Mac button and a setup guide alongside it. The page states the arrangement in one line.

The page also states a floor that the headline does not. Directly under the download button it reads Requires macOS 15 Sequoia or later. That single line settles the question for anyone on an older machine, and it sits at odds with the phrasing about running on any Mac. A Mac still on Sonoma 14 or earlier cannot install this build at all, so the comparison on that machine is not between the app and the website. It is between the website and whatever else can put the site in its own window.

Check the version before reading any further comparison. The Apple menu, then About This Mac, shows it in one step.

Distribution outside the Mac App Store is now the pattern rather than the exception in this category. The desktop clients for several of the best known assistants are direct downloads from their publishers' sites, and a Mac App Store search for their names returns unrelated third party products. Reading that absence as proof that no Mac client exists sends people to unofficial lookalikes, which is the actual risk in this search.

Two consequences follow from a direct download. Updates come from the application's own updater rather than the App Store update list, so an app that stops checking in quietly falls behind. Removal is a matter of deleting the app and its support files rather than a single store action, and an agent with system access leaves more behind than a chat window does.

The mobile app does not fill the gap either. The Perplexity iOS listing sits under Perplexity AI Inc. with a minimum of iOS 18.0, and it is not offered for installation on Apple silicon Macs the way some iPad apps are. On a Mac, the choices are the direct download or the website. There is no store route.

What the app contains now

The macOS app is the container for Personal Computer, which is an agent rather than a search field. Perplexity's description of it covers a task bar summoned by a keyboard shortcut from anywhere on the Mac, awareness of the frontmost application, control of native applications including Mail, Finder, and Slack, access to folders that get connected to it, and a voice mode.

That is a different product from the one most people picture when they search for this app. Someone who wanted a faster way to reach a search box is being offered software that clicks and types on their behalf.

The setup guide lists five steps, and the shape of the product is visible in the order of them. Download the macOS app. Install Comet. Allow the macOS permissions. Connect folders and applications. Pair a phone, which handles two factor prompts and approves sensitive actions while away from the Mac.

The always on framing on the same page is worth noticing too. Perplexity describes Personal Computer as running around the clock on a Mac mini inside the macOS app, reaching connected folders, native applications, and the web. That is a description of a machine left running as a worker, which is a legitimate use and a long way from an answer box.

A phone pairing step for approving actions is a strong signal about scope. Software that only answers questions does not need a second device to authorise what it does. Reading the setup checklist before downloading is the fastest way to decide whether this is the tool being looked for or a larger one that happens to share the name.

The permissions it asks for

The setup guide is direct about what macOS will prompt for, and the list is worth reading in full before starting.

macOS will prompt for Accessibility (so the agent can click and type), Screen & System Audio Recording (so it can see what's on screen), and Full Disk Access (so it can read your files). Approve each when asked. Source: perplexity.ai

Those three are among the strongest grants macOS offers. Accessibility allows synthetic input across every application. Screen recording captures whatever is displayed, including windows belonging to other applications. Full Disk Access reaches files that the sandbox normally keeps out of reach, including mail stores and backups.

None of that is hidden, and the reasons given are honest about why each one is needed. An agent that cannot see the screen cannot act on it. The point is that the decision is a real one rather than a formality, and it is a different decision from installing a chat client.

The context matters as much as the grant itself. A personal Mac is one situation. A machine holding client files under a confidentiality agreement, patient or student records, or source code covered by an employer's policy is another. On a managed device, these approvals may be blocked by policy, and enabling them anyway can put the machine out of compliance.

Anyone who wants the search product without the system access should stop before that step. The search product is a website, and it works in any browser without a single permission prompt.

Comet is a separate thing

Perplexity also publishes Comet, a browser built on Chromium with the assistant integrated into it, described on its page as available for Mac, Windows, iOS, and Android. The setup guide places it inside the Personal Computer flow, because web tasks are handed to Comet so the agent can navigate signed in sites and fill forms.

For someone evaluating what to install, that means three separate things carry the Perplexity name on a Mac, and they are not interchangeable.

What it is How it arrives What it does

Perplexity macOS app Direct download from perplexity.ai Hosts Personal Computer, the agent

Comet Direct download from perplexity.ai A full browser with the assistant built in

perplexity.ai Any browser The search and answer interface

Installing a whole second browser is its own decision. A browser holds sessions, extensions, history, and default handler status, and moving daily browsing into a new one is a bigger change than adding an application. Someone who only wants answers in a window does not need to switch browsers to get them.

When the site in its own window is the better fit

The third row of that table is the one most searches are actually aiming at. A window that opens straight to the answer interface, sits in the Dock, appears in the application switcher, and does not take over the machine.

That shape can be built from the browser already installed. A Mac window running on Chrome, Brave, Edge, Vivaldi, or another Chromium engine keeps the extensions that are already set up, keeps the sign in that is already done, and inherits the browser's updates without a second updater running in the background. Nothing new asks for Accessibility or Full Disk Access, because a window on a website needs neither.

It also solves the account problem cleanly. Separate windows can use separate browser profiles, so a personal account and a work account stay signed in at the same time instead of trading places. Anyone running two subscriptions, or one personal and one supplied by an employer, hits that limit within a week of daily use.

What a window of that kind cannot do is the thing the agent exists for. It will not open Finder, rename files, or drive another application. The honest comparison is between two different jobs rather than two versions of the same one. The feature list for that kind of tool sets out what a browser based window carries over, and the catalogue of services shows how many sites people keep in one.

Reading the search results before installing

Search results for this term mix several eras of the product, and dates matter more than usual here. Articles written when the macOS client was a simple search window describe an application that has since changed shape. Articles written about Comet describe a browser. Articles about the iPhone app describe something that does not install on a Mac at all.

Three checks sort them quickly. Look at whether the article mentions permission prompts, because the current app asks for three significant ones. Look at whether it mentions a phone pairing step. Look at whether it distinguishes the browser from the assistant. A piece that does none of those three is describing an earlier version.

The same caution applies to download links. The file served from perplexity.ai is the publisher's. Anything served by a download aggregator or a store listing from an unfamiliar developer is not, and for software that will be granted Accessibility and Full Disk Access, that distinction is not a small one.

Undoing the install if it is not the right fit

Trying the agent and deciding against it is a reasonable outcome, and the reversal is not complicated as long as it is done in the right order. Permissions come first, because they persist independently of the application.

The three grants live in System Settings under Privacy and Security, in the Accessibility, Screen and System Audio Recording, and Full Disk Access panes. Each pane holds a list with a switch beside every application that has been granted that capability. Turning the switch off revokes the access immediately, and removing the entry from the list clears it entirely. Doing this before deleting the application avoids leaving stale entries behind.

Login items are the second place to check. Software that summons a task bar from anywhere on the Mac generally starts with the system, and that setting sits in System Settings under General and Login Items. An agent that is no longer wanted should not still be launching at every restart.

Connected folders are the third. The setup step that points the agent at Downloads, Desktop, or project folders creates an ongoing relationship, and disconnecting those inside the application before removing it is cleaner than deleting the application and hoping the association goes with it.

Comet, if it was installed alongside, is a separate removal and a separate question. A browser also holds the default handler setting for web links, so checking System Settings under Desktop and Dock for the default web browser is worth a moment after removing it. Otherwise links keep opening in a browser that is no longer there.

The order that avoids loose ends is permissions first, login items second, application last.

What to change first

Decide which of the three products is actually wanted before downloading anything. If the goal is an agent that operates the Mac, follow the setup guide and read each permission prompt as it appears. If the goal is a fast, permanent place to ask questions, put the site in a window of its own on top of the browser already installed and skip the permissions entirely. Kagemusha builds that second kind of window, and the same approach covers every other assistant kept in a permanent tab.
