The desktop OS available today
Microsoft Windows (11, 10, Server)
The most-used desktop OS in the world (~70% of PCs). Supports virtually any commercial software, AAA games and recent hardware. Windows 11 brings deep Microsoft 365 integration, Copilot, heavy telemetry and higher hardware requirements (TPM 2.0, Secure Boot). Windows 10 remains the most used by stability and compatibility, but free support ends October 2025.
macOS (Sequoia, Sonoma, Ventura)
Apple's OS, exclusive to Mac hardware. Unix-based (Darwin), with a closed but very polished ecosystem. Leader in professional creative sectors (audio, video, design). Better iPhone/iPad/Apple Watch integration than any alternative. Limitation: only runs on Apple hardware, not licensable to PCs.
Linux (hundreds of distributions)
Huge family. Main distros:
- Ubuntu (Canonical) — most popular, friendly, 5-year LTS. Snap by default.
- Linux Mint — Ubuntu-based, Cinnamon desktop very similar to Windows, ideal for Windows-user migration.
- Debian — Ubuntu's base, ultra stable, ideal for servers and advanced users.
- Fedora (Red Hat) — newer package versions, base for RHEL/Rocky/AlmaLinux.
- Arch Linux / Manjaro — rolling release, total control, steep curve (Arch) or friendlier (Manjaro).
- openSUSE — popular in European enterprise, standout YaST tools.
- Pop!_OS (System76) — Ubuntu optimized for creative and gaming use, excellent NVIDIA GPU support.
- Elementary OS — macOS-like look, very polished for novice users.
- Kali Linux / Parrot — specialized in pentesting and offensive security.
- Enterprise distros: RHEL (Red Hat), SUSE Linux Enterprise, Oracle Linux — paid, with 10+ year support.
BSD (FreeBSD, OpenBSD, NetBSD)
Unix family older than Linux, known for extreme stability and security focus (OpenBSD). Used in routers (pfSense/OPNsense are FreeBSD derivatives), firewalls, commercial NAS and internet backbones. macOS and PlayStation 5 are BSD derivatives. Less common for general desktop.
ChromeOS
Google OS based on Linux, optimized for Chrome browser + Android apps + now some Linux apps. Designed for Chromebooks. Excellent for education, browsing and cloud work. Limited for heavy professional software.
Mobile operating systems
Android (Google, Linux kernel based) — 70%+ of world market. iOS (Apple) — 28%, dominant in US and premium markets. Not applicable for desktop, but the choice shapes many SMB productivity decisions.

Detailed pros and cons
Windows — pros
- Universal compatibility with commercial software, especially in specific sectors (accounting, engineering with AutoCAD, finance).
- Gaming without limits; best support for recent hardware.
- Familiar for 90% of users — minimal learning curve.
- Enterprise domain integration (Active Directory), Microsoft 365, Azure.
- Tech support widely available.
Windows — cons
- Significant license cost in large fleets.
- Heavy telemetry and built-in ads.
- Forced updates that sometimes break functionality.
- Windows 11 obsoletes perfectly functional hardware via TPM/Secure Boot requirements.
- More vulnerable to malware than alternatives (not by bad architecture, but by being the main target).
macOS — pros
- Hardware and software optimized together — very smooth experience.
- Excellent for professional creative sectors (Logic Pro, Final Cut, native Adobe ecosystem).
- Unix-based — powerful terminal, first-class dev tools.
- Apple Silicon (M1/M2/M3/M4) offers unbeatable performance/power for laptop.
- Excellent iPhone/iPad integration.
- Better privacy than Windows (though not perfect).
macOS — cons
- Only runs on Apple hardware — expensive and no options.
- Gaming very limited.
- Industrial niche software frequently unavailable.
- Low repairability (soldered components, proprietary tools).
- Closed ecosystem — high future vendor lock-in.
Linux — pros
- Zero cost. No licenses, no renewals.
- Runs on old hardware (10+ year PCs revived with Lubuntu).
- Full control: user decides everything, not the OS.
- Privacy: no telemetry by default in most distros.
- Free software included (LibreOffice, GIMP, Firefox, VLC) — everything an average user needs without paying anything.
- Excellent for development, servers, automation, IT.
- Huge free community support.
- More secure by architecture and smaller attack surface.
Linux — cons
- Specific commercial software unavailable (full Adobe Creative Suite, native AutoCAD, some AAA games with anti-cheat).
- Driver support variable — especially WiFi, fingerprint readers, NVIDIA GPUs in some cases.
- Learning curve for deep issues (terminal, configuration).
- Fragmentation: dozens of distros, package formats (deb, rpm, snap, flatpak, AppImage) — confusing at first.
- Gaming improved a lot with Proton but incompatibilities remain.
- Official enterprise support costs (Red Hat, SUSE) — free only if you DIY with community.
Recommendations by user profile
Basic home user (browsing, email, office, Netflix)
Anything works. From Windows wanting to keep same: Windows 10/11. Want to stop paying licenses: Linux Mint or Zorin OS. Buying Mac by preference: macOS.
Tight budget or old PC
Linux Mint, Lubuntu or Xubuntu. Revives any 10-year PC with smooth experience. Zero cost, no ads, no telemetry.
Creative professional (design, video, audio, photography)
macOS on MacBook Pro M-series. Industry standard, pro software optimized for Mac first, excellent hardware. Alternative: Windows with good GPU if budget can't reach Mac.
Programmer, devops, software engineer
macOS or Linux. Both Unix-based — terminal is where modern professional development lives. Windows with WSL2 is a viable alternative. Pure Linux is closest to the server where your code will run.
Sysadmin, networking, security
Linux (Ubuntu, Debian, Fedora) or specialized derivatives (Kali, Parrot for pentesting). Some use Mac for Unix terminal and portability.
Engineering or science student
Linux (Ubuntu, Pop!_OS) or Mac depending on budget. Python, R, MATLAB, simulators run well on both. Sectors with very specific software (AutoCAD, SolidWorks): Windows.
Gamer
Windows 11 is the dominant choice. Linux with Steam Proton + AMD GPU is a viable alternative improving every year — Steam Deck proves it's feasible.
Small business / general office
Windows 11 Pro remains the standard by Microsoft 365, AutoCAD, accounting software compatibility. For specific roles (reception, basic computing) Linux Mint saves licenses and runs with much less maintenance.
Company with servers
Servers: Ubuntu Server LTS, Debian, Rocky Linux (free) or RHEL (paid with support). Windows Server only if you need deep Active Directory or specific Microsoft products (Exchange on-premise, SQL Server).
Education / schools
Linux (Ubuntu, Edubuntu) or ChromeOS on Chromebooks. Dramatically reduces total cost and enables reuse of donated hardware.
Kiosk, POS, signage
Minimal Linux (Ubuntu Core, Alpine, Raspberry Pi OS) or Windows IoT Enterprise for specific cases. Zero distractions, manageable remote configuration.
The "must pay for Windows" myth
For uses where the OS is transparent to the user (browsing, email, office, video), the Windows cost is 100% avoidable. Linux Mint or Zorin OS deliver the same visual experience with zero learning curve, no licenses and less malware. Before buying the next pre-installed-Windows machine, consider asking for one without OS (DOS) and install Linux — saves US$ 100-200 per unit, which multiplied across the office is meaningful budget.
The best OS is the one that lets you do your work with the least friction and lowest total cost. For most SMBs, that's a mix: Windows on desktops running specific software, Linux on servers and infrastructure, macOS where the creative sector justifies it. There's no single winning OS — there's a right tool per scenario.
OS isn't identity — it's a tool
"Holy wars" between Windows, Mac and Linux users are nonsense today. Each is good for its purpose. Changing OS doesn't make you a better engineer, designer or freer person. What matters is choosing what lets you work best for what you need to do, and keeping an open mind to alternatives when context changes.
Need help choosing or migrating OS?
If you're evaluating migrating offices to Linux, configuring Mac on enterprise fleet, or just deciding which OS to buy for your next purchase, tell me what you need to do and I'll recommend the combination that performs best. I do migrations, install, configure and leave the environment productive from day one.
