Most “best reference manager” roundups are written platform-agnostically, as if Zotero, EndNote, and Mendeley behave identically on Windows and macOS. They don’t. The failures that actually send a Mac-using researcher searching for help are specific: a Word plugin that silently disappears after a macOS or Office update, a browser connector that quietly loses features on an older macOS version, or a citation tool that only ever supported Word and never will support Pages or Google Docs the way it does on Windows. This guide covers what genuinely differs on macOS for each major reference manager, plus the handful of tools built for Mac and nothing else.
Why platform matters more than feature lists here
Reference managers are cross-platform on paper, but the parts that actually break — the word-processor integration layer, the browser extension, and the update cadence of the underlying OS — are where platform differences show up in practice. A feature grid that just lists “Windows, Mac, Linux” as a checkbox misses this entirely. The sections below focus on the macOS-specific mechanics: what version of macOS a tool actually requires, what happens when it falls behind, and which install order avoids breaking things.
Zotero on macOS
Zotero’s own system-requirements page sets a real floor: macOS 10.15 (Catalina) or later for the desktop application, and Word 2016–2024 or Microsoft 365 for the Word plugin — the same version range Zotero supports on Windows, so there’s no separate Mac-only Word compatibility gap to worry about. Where macOS version genuinely matters is the browser Connector: Zotero’s documentation states that macOS 11 and 12 are served an older build of the Connector with fewer features than what current macOS releases get, and that Safari support specifically depends on the OS — Safari 18 and later, which is itself gated to macOS 13 (Ventura) or newer. A researcher troubleshooting a missing Connector feature on an older Mac may be running an intentionally reduced build, not a broken one.

EndNote on macOS
EndNote maintains genuinely separate Windows and macOS documentation trees for a reason: the install and repair paths are different programs, not the same dialog with different keys. The single most common cause of a missing Cite While You Write (CWYW) tab applies on both platforms but bites Mac users especially often in practice — installing or upgrading Microsoft Word after EndNote breaks the integration, because the add-in is written into the Word installation that existed at the time EndNote ran. On macOS specifically, Clarivate’s own EndNote 2025 documentation calls out quitting every Office application, not just Word, before installing or repairing EndNote — a step that’s easy to skip and that CWYW troubleshooting guides written from a Windows-first perspective often don’t emphasize. The full install-order rule and repair procedure, verified against Clarivate’s current EndNote 2025 docs, is at Installing EndNote Cite While You Write in Word; for using EndNote day to day once it’s working, see the EndNote first-project walkthrough.
Mendeley Cite on macOS
Mendeley’s current citation tool, Mendeley Cite, is Word-only on every platform — Elsevier’s own support documentation confirms it does not work with Google Docs, and there’s no Mac-specific workaround that changes that. This matters more on macOS than it might seem, because Mac-based researchers collaborating with Google Docs-first co-authors (a common pattern in humanities and social-science departments) will find Mendeley Cite simply doesn’t reach that document at all, regardless of macOS version. If Google Docs integration is a requirement, see Citation Managers That Work With Google Docs — Zotero is currently the only one of the major reference managers with a native, first-party Google Docs plugin.
ReadCube Papers on macOS
ReadCube Papers ships a native macOS desktop application alongside its Windows, iOS, and web clients, so there’s no macOS-specific installation gap the way there can be with the Word-plugin-based tools above. Its citation tool, SmartCite, inserts citations into both Word and Google Docs, which puts it ahead of Mendeley Cite specifically for Mac researchers who write in Google Docs. See ReadCube Papers vs. Zotero for the full feature and pricing comparison, including where ReadCube’s AI-assisted discovery layer and Zotero’s free/open-source model each make more sense.
Bookends: the Mac-only holdout
Nearly every reference manager a research office recommends today is cross-platform by design. Bookends (Sonny Software) is a real exception worth knowing about specifically because it isn’t: it is built exclusively for macOS and iOS/iPadOS, with no Windows or Linux client at all and no plan to add one. That’s a meaningful trade-off in either direction — a Mac-only tool can lean harder into macOS-native conventions (AppleScript automation, tight Finder and Preview integration) than a cross-platform Electron-style app can, but it’s a non-starter the moment a co-author or a lab collaborator is on Windows. Because Bookends’ current pricing and feature set change independently of this guide, confirm both directly at the vendor’s own site before deciding rather than relying on a secondhand figure.
Apple Silicon: how to actually check, not guess
Whether a given build of Zotero, EndNote, or Mendeley Cite is running natively on Apple Silicon or under Rosetta 2 translation isn’t something worth guessing about or trusting a marketing claim for — macOS will tell you directly. Open Activity Monitor, find the application’s process, and check the Kind column: it reads “Apple” for a native Apple Silicon process and “Intel” for one still running translated under Rosetta. A translated process isn’t broken, but it does carry real overhead — slower launch and higher CPU use are the most commonly reported symptoms — so on a new Mac it’s worth the ten-second check rather than assuming every install is already native.
Choosing for macOS specifically
- Heavy Word user, want the most macOS-specific troubleshooting documentation available: EndNote — but follow the install-order rule above from the start rather than discovering it after a Word update breaks CWYW.
- Google Docs is the actual writing environment: Zotero (native plugin) or ReadCube Papers (SmartCite) — not Mendeley Cite, which doesn’t support Google Docs on any platform.
- Want to stay entirely free and open-source, with strong Safari/Chrome capture: Zotero, keeping in mind the reduced-Connector-feature caveat on macOS 11/12.
- Want deep macOS-native integration and don’t need Windows compatibility, ever: Bookends is the one genuinely Mac-only option among established tools.

Frequently asked questions
Does Zotero run natively on Apple Silicon Macs?
Check directly rather than assume: open Activity Monitor while Zotero is running and look at the Kind column for that process. “Apple” means it’s native; “Intel” means it’s currently running under Rosetta 2 translation, which works but carries overhead.
Why did my EndNote Word tab disappear after a macOS or Office update?
The most common cause on both platforms is install order: if Word gets installed, reinstalled, or upgraded after EndNote, the Cite While You Write add-in reference breaks. On macOS, Clarivate’s own documentation also calls for quitting every Office application, not just Word, before reinstalling or repairing EndNote. See the full repair walkthrough.
Can I use Mendeley Cite with Google Docs on a Mac?
No. Mendeley Cite is Word-only on every platform, macOS included, per Elsevier’s own support documentation. There is no Mac-specific workaround.
Is there a reference manager built only for Mac?
Bookends (Sonny Software) is the clearest current example — it runs on macOS and iOS/iPadOS only, with no Windows or Linux client.
