Must-Have Mac Apps for a Windows-to-macOS Switcher

One of my oldest friends is, as I write this, watching a UPS truck slowly converge on his front porch. Inside the truck is his first MacBook. After a solid 25 years of Windows-centric computing, he's about to cross over.

I've been on the other side of that crossing for nearly 17 years now.

Windows still pays the bills — that part may never change. But my daily-driver, the place where most of my actual knowledge work happens, sits firmly in the *nix world. And since BSD Unix has always been the core of macOS, I ended up awash in Macs almost by accident. I still run more PCs (Linux and Windows) than Macs in the house — but that ratio is getting closer every year.

Here's what I'd tell my friend, or anyone else making the jump: no matter which OS tickles your fancy, Mac and Linux skills are table stakes now. Bash, a decent terminal, package managers — you're going to need them. And yes, iCloud and the App Store are genuinely pleasant once you let them be. More and more nerds I know have made this jump, and nobody I've asked wants to go back once it "clicks."

So this is the list I wish someone had handed me 17 years ago -- except some apps/tools in this list didn't exist yet. Productivity, utilities, and power-user tools — no audio/video creative apps, no gaming (that's another blog article, but creativity -- hooo boy is it fun on Mac). The long list below just includes the things I actually reach for in my workday in IT Ops work.

If you only remember one thing from this post: install Homebrew first. Everything else gets easier after that.

Password Management & Security

Apple's Passwords app is quietly excellent now. Use it. But keep a cross-platform backup — for me that's 1Password. It's best-in-class, integrates with every browser, and stores more than passwords: API keys, secure notes, 2FA codes, SSH keys. One place, across every machine I own.

A few Safari extensions I treat as non-optional:

• 1Blocker / AdGuard for Safari — ad and tracker blocking
• Dark Reader for Safari — dark mode for every website. Noir is a solid alternative.
• Hush — silences the cookie / GDPR popup carnival

Window Management & Desktop Enhancement

This is the first place most Windows switchers hit a wall. macOS does not ship with real window snapping or a proper Alt-Tab. You're going to want to fix both on day one.

• AltTab — a proper Windows-style Alt-Tab. Essential for switchers.
• Rectangle Pro — snap and tile windows the way Windows 11 Snap Layouts do
• Magnet — another popular snapping option if Rectangle doesn't click
• BetterSnapTool — drag-to-snap window management, same space
• BetterTouchTool — advanced trackpad and mouse gestures plus automation. Run, don't walk. This is the one app I'd reinstall first on a fresh Mac.
• BetterMouse — precision mouse customization, great for non-Apple mice. Pairs well with BetterTouchTool.
• Swish — trackpad-based window gestures for when you're not on a mouse
• BetterDisplay — external monitor resolution and scaling control. Critical for multi-monitor setups. I've mostly stopped using anything else.
• Bartender 6 / Ice — tame the menu bar (hide and reorder icons). An absolute must on any MacBook with the notch.
• Reminders MenuBar — quick access to Apple Reminders from the menu bar, which syncs cleanly with iPhone and iPad

Keyboard & Input Customization

• Karabiner-Elements — deep keyboard remapping. If you're plugging a Windows keyboard into a Mac, this is how you get your muscle memory back.
• KeyCue — shows every keyboard shortcut for any app on demand. Great for learning to reach for ⌘ instead of Ctrl.
• Cheatsheet — hold ⌘ to see shortcuts for the current app. I love this one.
• Espanso — cross-platform open-source text expander. macOS has built-in text replacement, but Espanso goes further. Not essential, but nice.
• SteerMouse — advanced mouse button customization. Those right-click menu items you miss from Windows? Get them back here.
• Pure Paste — always paste as plain text. Saves you from a thousand little formatting fights.

Clipboard, Screenshots & OCR

macOS has a surprisingly good built-in screenshot workflow (⌘⇧5, then Return). Learn it. But you'll still want these:

• CleanShot X — the best screenshot and annotation tool on Mac, full stop. Replaces Snipping Tool and then some.
• TextSniper — OCR any text on screen and copy it. Feels like a cheat code.
• Redact — quickly blur or redact sensitive info in images
• Hand Mirror — a one-click webcam check from the menu bar. Surprisingly useful if you live in Zoom.

File Management & Storage

• The Unarchiver — handles every archive format you'll ever encounter
• Keka — another great archiver with compression. Handles a lot of Python and *nix-flavored archives. I use both.
• DaisyDisk — visual disk space analyzer. Think WinDirStat but prettier.
• Carbon Copy Cloner — full disk backup and cloning. The one I trust.
• GoodSync — file sync across devices and cloud. More involved than CCC, different use case.
• Google Drive / OneDrive — don't stop at iCloud Drive
• Cyberduck — FTP / SFTP / S3 / WebDAV transfers
• Recents — quick access to recent files from the menu bar
• AutoMounter — auto-mount network drives

Browsers

• Safari — default, and genuinely excellent if you're on battery. I love Chrome, but when I'm mobile and watching the battery icon, Safari will literally net me 3+ hours of extra runtime.
• Google Chrome — the standard
• Firefox / Firefox Developer Edition — privacy-leaning
• Microsoft Edge — familiar for switchers, syncs with your Microsoft account. If you spend time in Azure or M365 tenant management, this is a must.
• DuckDuckGo — privacy-first browser. I keep it around for testing.

Browser Extensions Worth Naming

• Tampermonkey — userscript manager. Live-mod web pages with community scripts. Great for things like privacy-enhancing Facebook tweaks.
• Copytables — copy HTML tables cleanly
• Notion Web Clipper / Obsidian Web Clipper / MarkDownload — web-to-Markdown clipping. I use all three.
• OneTab — tab management for Chrome

Writing & Markdown

• Obsidian — I do all my writing here. Markdown-based, local files, and it's the center of my whole knowledge system.
• Zettlr — academic Markdown writing, a good backup to Obsidian
• Typora — clean WYSIWYG Markdown editor
• Scrivener — long-form writing (books, screenplays, research)
• Ulysses — polished writing app for Mac/iOS, subscription-based
• CotEditor — lightweight plain text editor, the closest thing to Notepad++ on Mac

Note-Taking & Knowledge Management

• Obsidian — still my main, still my main recommendation. It's the one app I'd rebuild my entire workflow around.
• Notion — all-in-one workspace. A lot of dev and startup teams live here.
• Apple Notes — comes free, decent for quick captures, not where I do real thinking
• Microsoft OneNote — familiar for Windows users, still not my favorite
• Reeder — RSS reader. Good blogs and good feeds are still out there.
• Anybox — bookmark and link manager
• Kiwix — offline Wikipedia and other reference dumps
• Zotero — academic reference and citation manager
• Granola — AI meeting notes

AI Tools

• Claude — Anthropic's desktop app plus Claude Code for terminal work
• ChatGPT — OpenAI's desktop app
• Copilot — Microsoft's take
• Codex — OpenAI's coding agent CLI
• Cherry Studio — multi-model AI chat client
• Chatbox — local or cloud AI chat client
• LM Studio — run local LLMs on your Mac. Apple Silicon is surprisingly capable here.
• DiffusionBee — local Stable Diffusion for images
• ComfyUI — node-based AI image workflow

Code Editors & Development

• Visual Studio Code — the standard. If you want AI in your editor, VS Code integrates with every LLM out there just fine. (I'd hold off on Cursor for the moment — you don't need it to get AI in your editor.)
• vim / neovim — my CLI text-editing favorite. And yes, you can exit vim. It's possible.
• Terminal — don't sleep on this. Honestly, the terminal has quietly become the best LLM agent and code editor of the last year. Get your Bash skills rolling.
• Sublime Text — lightweight and fast. My backup quick-edit tool.
• Xcode — Apple's IDE. You'll want it installed at minimum for Command Line Tools.
• GitHub Desktop — Git GUI
• GitHub Copilot for Xcode — AI code completion inside Xcode
• SnippetsLab — a solid code snippet manager, though honestly you can do this in Obsidian too
• Beyond Compare / CompareMerge2 — file and folder diff tools

Terminal & Shell

The built-in Terminal is fine. I actually like it. But keep these in mind:

• iTerm — a popular macOS Terminal replacement
• Ghostty -- a Zig (C++) popular Terminal I just discovered from another close friend, who just read this article. Well-worth checking out, seems more responsive than iTerm.
• PowerShell — yes, PowerShell runs on Mac. Your scripts and muscle memory come with you.

Virtualization — Running Windows (and Linux) on Your Mac

This is the section most Windows switchers care about most. Yes, you can run Windows on your Mac. But there's one thing you need to understand before you start.

The ARM Reality

Every modern Mac (2020 and later) runs on Apple Silicon — M1, M2, M3, M4, now M5. These are ARM-based processors. Fundamentally different architecture from the Intel/AMD x86-64 chip in your Windows PC. What that means for VMs:

• Always install ARM64 (AArch64) builds of your guest OS. Never x86/x64 ISOs.
• Windows has an official Windows on ARM build that runs natively on Apple Silicon and performs extremely well.
• Most Linux distros ship ARM64 ISOs now (Ubuntu, Fedora, Debian, and friends).
• If you try to install an x86 ISO, the hypervisor has to emulate the entire x86 instruction set. Performance drops to roughly 10–20% of native. Unusable for real work.
• ARM Windows can still run most x86 Windows apps through Microsoft's built-in translation layer — same idea as Rosetta 2 on macOS — so compatibility is rarely the blocker people expect.

Bottom line: ARM-first, always. Treat x86 ISOs as incompatible with your Mac and move on.

My Recommendation: VMware Fusion (Free Now)

VMware Fusion is the top pick. Broadcom made Fusion completely free for personal use — the full Pro license, no feature restrictions. It's the most capable and mature hypervisor on macOS outside of Parallels, with snapshots, linked clones, shared folders, USB passthrough, and enterprise-grade networking. If you used VMware Workstation on Windows, this is your direct equivalent: same company, same quality. Download it from the Broadcom support portal (free account required).

Honorable Mentions

• Parallels Desktop — polished and very friendly, but it's a $100+/year subscription. Its "Coherence" mode (Windows apps running alongside Mac apps) is slick, but I rarely want that anyway — most of my VM work needs an isolated sandbox. Fusion does most of the same things for free, so the recurring cost is hard to justify.
• UTM — free, open-source, QEMU-based. Great for throwaway VMs or weird OSes. Lacks the polish and performance tuning of Fusion. Fine for experimentation, not what I'd pick as a daily driver.
• Oracle VirtualBox — the classic free option from the Windows/Linux world. ARM support on macOS is still catching up. If you used VirtualBox on Windows, just know Fusion is the better pick on Mac.

Containerization

• Docker — containerization platform, essentially non-optional for developers. Runs Linux containers natively on macOS via a lightweight VM. Not a replacement for a desktop VM, but indispensable for dev workflows.

Remote Access

• Jump Desktop — remote desktop client, the best one I've found
• Remote Desktop Manager — multi-protocol remote access (free for a few sessions; team pricing above that)
• SecureCRT — SSH/Telnet terminal client. Probably the best GUI SSH client on Mac.

Communication

All the usual suspects are here: Slack, MS Teams, Zoom, Discord. There's a Signal client that mates to your phone. WhatsApp and Telegram, too. Nothing to prove here — they all just work.

Diagramming & Visual Thinking

• draw.io — free diagramming, the Visio alternative
• ExcalidrawZ — hand-drawn style diagrams
• Figma — design and prototyping
• SketchWow — quick sketch diagrams
• Canva — graphic design and presentations

Productivity & Task Management

• Obsidian — yes, again. I use it for tasks now too, not just notes.
• Microsoft To Do — task management that syncs with your Windows account
• Keynote / Pages — Apple's presentation and word processor
• Microsoft Excel / Word / PowerPoint / Outlook — the Office suite runs fine on Mac
• Google Docs / Sheets / Slides — Workspace, in the browser or as apps

Networking & Diagnostics

• WiFi Explorer / WiFi Signal — WiFi analysis and monitoring
• NetSpot — WiFi surveys and troubleshooting
• Wireshark — network packet analysis
• TripMode — control which apps are allowed to use data. A lifesaver when you're tethering.

Disk & System Utilities

• Blackmagic Disk Speed Test — benchmark storage speed
• AmorphousDiskMark — disk benchmark. Literally CrystalDiskMark for Mac.
• iBar Pro — menu bar battery and system monitor

Photo & Image Utilities

• Pixelmator Pro — powerful image editor. A legitimate Photoshop alternative, and Apple owns it now.
• Affinity — professional design suite (Photo, Designer, Publisher)
• Darkroom — photo and video editor

Miscellaneous Power User Tools

• Logitech Options+ — Logitech device management
• Amazon Kindle — ebook reader
• qBittorrent / Transmission — torrent clients
• Msg Viewer Pro — open Outlook .msg files on Mac
• Pandoc (CLI) — universal document converter
• TestFlight — beta app testing

Homebrew & CLI Must-Haves

Homebrew is the #1 must-install for any power user on macOS. It's the package manager macOS doesn't ship with — think apt, yum, or winget. Install from brew.sh and everything else on this list gets easier.

Essential CLI Tools (what I actually run)

Casks Worth Naming

The tl;dr for Any Switcher

If you scrolled to the bottom (I don't blame you), this is the short version:

1. Window management isn't built-in like Windows — grab AltTab and Rectangle Pro (or Magnet) on day one
2. Homebrew is non-negotiable* — it's how you install CLI tools and a lot of apps
3. iTerm replaces Terminal the way Windows Terminal replaced cmd.exe
4. Karabiner-Elements gets your muscle-memory keyboard shortcuts back
5. The Unarchiver / Keka — the built-in Archive Utility is thin, you'll want these
6. AmorphousDiskMark is CrystalDiskMark for Mac
7. PowerShell runs on Mac — your scripts and knowledge come with you
8. Quick Look is a macOS superpower — tap Space on any file. Enhance it with Syntax Highlight and Folder Preview.
9. VMware Fusion is free now — run Windows on your Mac at near-native speed. ARM64 ISOs only.
10. CleanShot X is the Snipping Tool replacement you didn't know you needed

Seventeen years ago I thought switching to Mac would mean giving something up. What I actually gave up was a bunch of friction I didn't know I was carrying — half of it keyboard shortcuts, half of it the quiet tax of keeping a Windows box healthy. What I got back was a Unix machine that happens to run the same infrastructure that makes the Internet work -- but can run iMessage too. Wild stuff. And I'm not even writing about Logic Pro and Final Cut Pro workflows, a whole other creative apps blog post -- for another time.

My friend's MacBook is probably on his porch by now. If you're standing where he is — first Mac in the box, a little nervous, not sure which hill to climb first — start with Homebrew, install AltTab and Rectangle Pro, open a terminal, and get to work. The rest of this list will still be here when you need it.

Final note: some minds just can't get into the mindset right away, and that's ok. No shame in your game if you still want to roll a Windows VM and stay in the solace of comfort, but STILL try to get a decent Mac skillset. Remember the "whynotboth.gif" meme, and stay multi-platform -- keep the Mac. Take the time. It won't happen overnight, but it's worth it.
