In the world of productivity software, Microsoft 365 (formerly Office 365) remains the gold standard for many professionals, offering seamless cloud integration, robust collaboration tools, and a polished user experience. However, for Mac users seeking a cost-free option, Apache OpenOffice stands out as a viable open-source alternative. Released as a free suite including Writer (word processing), Calc (spreadsheets), Impress (presentations), Draw (graphics), Base (databases), and Math (equation editor), OpenOffice has been a staple since its fork from the original OpenOffice.org project. As of 2025, it’s particularly appealing for budget-conscious individuals, small businesses, and educators on macOS.
But is it truly a match for Microsoft 365’s ecosystem? In this article, we’ll dive into the advantages and disadvantages of using Apache OpenOffice on Mac compared to Microsoft 365, drawing from user reviews, feature comparisons, and expert analyses. While both suites are fully compatible with macOS (including Apple Silicon via Rosetta for OpenOffice), the choice often boils down to cost, features, and workflow needs.
Advantages of OpenOffice for Mac
- Completely Free
- OpenOffice is open-source and costs nothing, making it highly attractive for students, small businesses, or anyone on a budget.
- Unlike Microsoft 365, which requires a subscription starting at around £9 per month (or £70 annually for personal use or £110 for family pack 5 devices 6 users accounts), OpenOffice is 100% free with no hidden fees or upsells. This makes it ideal for students, freelancers, or small teams on Mac who don’t want recurring costs. Users praise its high value-for-money rating (4.8/5 on platforms like Capterra), often calling it “very functional and does the job” without the bloat of premium features. In 2025, with economic pressures lingering, this no-cost model is a major draw for Mac users avoiding subscription fatigue.
- Cross-Platform Compatibility
- Available for macOS, Windows, and Linux, OpenOffice makes it easy to work across different operating systems without additional licensing fees.
- OpenOffice runs natively on macOS, Windows, and Linux, ensuring files created on your MacBook can be opened elsewhere without hassle. It supports the OpenDocument Format (ODF) as its standard, which is an ISO-approved open standard, promoting interoperability. Additionally, its multi-language capabilities—available in over 100 languages—make it a go-to for international teams, something Microsoft 365 handles well but often ties to regional licensing nuances. For Mac users in diverse environments, this seamless integration with the OS’s native themes enhances the overall experience.
- Supports a Wide Range of File Formats
- OpenOffice can open and save documents in formats like
.docx,.xlsx, and.pptx, along with its own OpenDocument formats.
- OpenOffice can open and save documents in formats like
- Lightweight and Simple
- It doesn’t require as many resources as Office 365, making it a practical choice for older Macs or those with limited storage.
- Community-Driven Development
- Since it’s open-source, it benefits from global contributions, bug fixes, and improvements without being locked into a commercial model.
- Built-in Security and Customization
- OpenOffice includes robust security features like digital signatures and encryption right out of the box, rivaling Microsoft 365’s protections without needing add-ons. Its customizable interface allows Mac users to tweak toolbars and themes to match Apple’s aesthetic, fostering a more intuitive workflow. Community-driven development means frequent bug fixes based on user feedback, keeping it lightweight and responsive for everyday tasks like drafting reports or crunching data in Calc.
- Resource Efficiency for Basic Needs
- For lighter workloads, OpenOffice’s suite feels snappier on older Macs or those with limited RAM, as it doesn’t demand constant cloud syncing like Microsoft 365. Reviews highlight its ease-of-use score (4.4/5), making it accessible for non-tech-savvy users transitioning from Microsoft tools.
| Aspect | Apache OpenOffice Advantage | Microsoft 365 Counterpoint |
|---|---|---|
| Cost | Free forever | Subscription-based (£70+/yr) |
| Languages Supported | 100+ | Strong but region-locked |
| Security Features | Built-in encryption | Advanced but cloud-reliant |
| Ease of Use (Rating) | 4.4/5 | 4.5/5 |
Disadvantages of OpenOffice for Mac
- Lacks Advanced Features
- Compared to Office 365, OpenOffice feels limited. Features like real-time collaboration, AI-powered editing, and advanced data analysis are missing.
- Outdated User Interface
- The interface looks dated compared to the polished, modern design of Office 365 apps. This can impact usability and appeal.
- Missing polish in areas like advanced charting, voice-to-text, or accessibility tools (e.g., no robust screen reader integration for students), OpenOffice feels dated compared to Microsoft 365’s AI-enhanced editing and presentation animations.
- Compatibility Issues with Microsoft Formats
- While it can open Microsoft Office files, complex formatting (charts, macros, smart art, etc.) doesn’t always transfer correctly.
- A persistent pain point: While OpenOffice can import DOCX, XLSX, and PPTX files, saving in these native Microsoft formats often leads to formatting glitches or requires workarounds. In 2025, this remains a drawback for teams sharing with Microsoft 365 users, as OpenOffice defaults to ODF and may prompt unwanted conversions. Mac users report encoding issues with CSV files and difficulty recovering lost documents, unlike Microsoft 365’s auto-save and version history.
- Slower Updates
- Development and updates are far less frequent than Microsoft’s regular feature rollouts and security patches.
- OpenOffice’s 32-bit architecture limits its efficiency on Apple Silicon Macs, causing lag with large files or complex spreadsheets—issues less common in Microsoft 365’s 64-bit, optimized apps. Updates are community-paced, leading to slower feature rollouts (e.g., no AI tools like Copilot). Customer support is a weak spot (3.9/5), relying on forums rather than Microsoft’s 24/7 help.
- No Cloud Integration
- Unlike Office 365, which integrates with OneDrive, Teams, and SharePoint, OpenOffice doesn’t offer built-in cloud storage or collaboration tools.
- Microsoft 365’s killer feature—real-time co-editing via OneDrive and Teams—is absent in OpenOffice, which lacks any mobile app for iOS or Android. For Mac users on the go (e.g., iPad integration), this means no seamless handoff between devices. Collaboration feels clunky, with no built-in chat or sharing tools, scoring lower in functionality (4.2/5 vs. Microsoft 365’s 4.6/5).
- OpenOffice’s 32-bit architecture limits its efficiency on Apple Silicon Macs, causing lag with large files or complex spreadsheets—issues less common in Microsoft 365’s 64-bit, optimized apps.

| Aspect | Apache OpenOffice Drawback | Microsoft 365 Strength |
|---|---|---|
| File Compatibility | Formatting glitches | Native support |
| Mobile Access | None | Full iOS/macOS apps |
| Updates | Community-driven (slow) | Frequent, feature-rich |
| Support (Rating) | 3.9/5 | 4.3/5 |
Which One Should You Choose?
- Choose OpenOffice if…
You want a free, lightweight office suite for basic tasks like writing, simple spreadsheets, and offline work without worrying about subscriptions. - Choose Office 365 if…
You need professional-grade tools, frequent updates, strong collaboration features, and seamless compatibility with colleagues or organizations that rely on Microsoft formats. - For power users, Microsoft 365’s advantages are undeniable. Its deep integration with macOS (e.g., Touch Bar support, Continuity features) and cloud ecosystem make it superior for remote teams.
✅ Bottom Line:
OpenOffice for Mac is a solid, budget-friendly option for casual or individual use, but Office 365 outshines it in terms of features, reliability, and collaboration—at a price. Its freedom and compatibility make it a ethical win over proprietary software. Yet, for collaborative pros or those embedded in Microsoft’s world, the disadvantages in performance and features tip the scales toward Microsoft 365.
Ultimately, test both: Download OpenOffice for free and trial Microsoft 365 to see what fits your Mac setup. If collaboration is key, consider hybrids like LibreOffice (a more actively updated fork). In a hybrid work era, the “best” suite is the one that boosts your productivity without breaking the bank.
