- First locate where your data is (iCloud, NAS, disks, clouds) and use compatible formats like exFAT to move it between systems.
- It supports multi-platform cloud services (Google Drive, OneDrive, Dropbox) and exports documents from Pages, Numbers, and Keynote to standard formats.
- Migrate browser bookmarks and passwords, as well as photos, email, and contacts from iCloud to services also accessible on Windows.
- Make a full backup before the change and take the opportunity to unify your workflow across apps and services compatible with both Mac and Windows.
Switching from a Mac to a Windows PC today is much less dramatic than it was a few years ago, but if you don't plan well, you can lose photos, projects, passwords, or important settings. The key to migrating from Mac to Windows without losing files is knowing where everything is located, what services you use (iCloud, Google, OneDrive, NAS, external drives, etc.), and how to securely extract that information.
In this guide, we'll take a detailed look at all the typical scenarios when switching from macOS to Windows : files in iCloud Drive, cross-platform cloud storage, NAS, external drives, photos, email, contacts, reminders, web browser, passwords, work projects (like music production sessions), and even practical differences between systems so the transition doesn't overwhelm you. The goal is for you to end up with your digital life working just as well—or even better—on your new PC.
1. Before migrating from Mac to Windows: locate and organize your files
The first step, though it may sound obvious, is to be clear about where your files actually are . It's not the same if everything is in iCloud Drive, on a NAS, on an external hard drive, or spread across several cloud services like Google Drive or OneDrive. Each case is managed slightly differently, and it's best to identify them before making any changes.
On many recent Macs, especially if you've followed Apple's recommendations, most of your documents will be in iCloud Drive : Desktop, Documents, and some application folders. But it's also very common to have data on a USB drive, a home server (NAS), or synced with Google Drive, Dropbox, or similar services.
Take a few minutes to review your Finder: Desktop, Documents, Downloads, Movies, Music, and Pictures folders , as well as any specific work folders (for example, for music production or design). Make a note of where each important piece of information is located, because this will help you determine the best strategy for each situation.
2. Migrate files from iCloud Drive to Windows
If you had everything integrated into the Apple ecosystem, it's very likely that a large portion of your data is stored in iCloud Drive. You can still use iCloud on Windows , but the experience isn't as seamless as on a Mac, and in many cases, it's more efficient to move or duplicate those files to a more cross-platform cloud service like Google Drive, OneDrive, or Dropbox.
You basically have three strategies to get your files out of iCloud Drive and onto Windows without losing anything in the process :
2.1 Copy everything to a compatible external hard drive
The most direct option is to copy your iCloud Drive data to an external hard drive from your Mac and then transfer that drive to your Windows PC. It's essential that the drive is formatted with a file system compatible with both operating systems, such as exFAT , to avoid read and write problems.
On your Mac, first make sure all your iCloud Drive files are downloaded locally (without the empty cloud icon). Then, open a Finder window, go to iCloud Drive, and drag all the folders and files to the external drive. Depending on the amount of data, the process will take more or less time, but you only need to do it once.
Once you're finished, connect that drive to your Windows PC. From there, you can copy what you need to your PC's internal drive and, if you want cloud synchronization, upload it to Google Drive, OneDrive, or your preferred service. This solution is ideal if you like to manually control what happens to each file.
2.2 Install iCloud for Windows
Apple offers an official iCloud app for Windows that lets you sync iCloud Drive, Photos, passwords, and bookmarks with your PC. It's a convenient way to avoid changing anything on your Mac and simply add access on your new computer.
It's simple: download iCloud for Windows from the Microsoft Store or the Apple website, sign in with your Apple ID , and choose what you want to sync. From then on, you'll have an iCloud Drive folder in File Explorer and can work with your documents as if they were local.
However, the experience isn't as seamless as on macOS, and in practice, many users prefer a more standard cloud service on Windows (OneDrive is integrated, for example). This iCloud option on Windows makes sense especially if you plan to continue using an iPhone or iPad and want to keep the Apple ecosystem active in parallel.
2.3 Migrate your iCloud data to another multi-platform cloud
If your goal is to simplify your digital life, the best option is probably to migrate your files from iCloud Drive to a multi-platform cloud service like Google Drive, OneDrive, or Dropbox, which work equally well on macOS, Windows, Android, and iOS.
On your Mac, install your chosen cloud desktop client. Drag everything from your iCloud Drive to the corresponding iCloud folder to begin syncing. Depending on your data usage and internet connection, the upload may take some time. Do not close your Mac or put it to sleep until it is complete.
When everything is in the cloud, on Windows you just need to install the same service and use the same account . Your new PC will download and sync the files, and they'll be available on any computer or mobile device you use in the future, not just your Mac.
2.4 Be careful with Pages, Numbers and Keynote
A common pitfall when switching from Mac to Windows is forgetting that Pages, Numbers, and Keynote use proprietary formats that don't open directly in Windows. If you have important work documents in these apps, it's a good idea to convert them before leaving your Mac.
Open each file in its corresponding application and use the " Export to a standard format" option . For example, in Pages, export to DOCX (Word), in Numbers to XLSX (Excel), and in Keynote to PPTX (PowerPoint). It takes a little work, but you'll avoid problems when you try to open them on your new PC.
3. Data on NAS or external hard drive: how to transfer it to your PC
If you're someone who takes care with file management, you might have your documents on a NAS (networked storage device) or on one or more external hard drives . In that case, migration is simpler because most of the work has already been done.
For a NAS, you usually just need to connect your new PC to the same network and mount the shared folders using SMB. Most NAS devices from brands like Synology, QNAP, and similar have specific guides for Windows and macOS, but the procedure is very similar: locate the server, enter your username and password, and access it as you would any other network drive.
In the case of USB drives, the only truly critical factor is the file system format . If the drive is formatted as APFS or HFS+, Windows won't be able to read it natively. In that scenario, from your Mac, you'll need to copy the data to another drive (or to a NAS), format the problematic drive as exFAT or NTFS , and then copy the data back to your new PC to use it without further complications.
Remember that, by default, Windows writes to NTFS and exFAT without issue , while macOS is better suited to APFS, HFS+, and exFAT. If you plan to continue using the drives on both systems, exFAT is usually the more practical option, provided you don't need the advanced features of NTFS.
4. Migrate using cross-platform clouds (Google Drive, OneDrive, Dropbox…)
If you were already using a public cloud service like OneDrive, Google Drive, or Dropbox , you're in luck. In that case, migrating your files is almost effortless, and the main task will be logging into your account on your new PC.
On your Mac, make sure your cloud clients are up to date and that the files you want to keep are synced. You can force certain folders to be "always available offline" so they download completely before you stop using your Mac.
On Windows, reinstall the client for your platform, log in, and wait for your PC to download or mark your folders as available . In some cases, such as OneDrive, you can choose what to keep only in the cloud and what to save locally—very useful if your laptop's internal hard drive is smaller than your old Mac's.
This approach is also ideal if you use multiple devices: your data becomes truly machine-independent . If you switch to another computer tomorrow, you'll just need to log in to the cloud and you're good to go.
The web browser has become central to our daily lives: bookmarks, history, extensions, and, above all, passwords . Fortunately, if you use Chrome, Edge, Firefox, Brave, or any account-based browser, switching to Windows is quite simple.
If you already use Chrome or Edge on your Mac, make sure you're signed in with your Google or Microsoft account and that bookmark, history, password, and other data syncing is enabled. On Windows, install the same browser, sign in with the same account, and you'll have the same experience in minutes.
The only truly problematic case is Safari , because there's no longer a modern version for Windows. In that scenario, the best approach is to choose which browser you're going to switch to and export your Safari data to import it later into Chrome, Edge, or Firefox.
5.1 Switching from Safari to Firefox
If you choose Firefox as your primary browser on your new PC, install it on your Mac first. From there, go to Settings > General > Import Data and select Safari as the source. Firefox will then import your bookmarks, history, and other compatible data.
Next, on Windows, install Firefox, sign in with your Firefox Sync account, and let the data sync between devices . You'll have your bookmarks and, in many cases, your credentials ready to use.
For Chrome and Chromium-based browsers (Brave, Vivaldi, Edge with some variations), the procedure involves a small manual step. From Safari on macOS, go to File > Export and export your browsing data.
A ZIP file will be generated which, when extracted, will contain at least two key files: Bookmarks.html and Passwords.csv . You will import the first one into Chrome from Settings > Import bookmarks and settings > Bookmarks HTML file. You can use the second one to import your passwords into Chrome or an external password manager.
Note that some browsers have different locations for the import menu, but the logic is identical: select the HTML file for bookmarks and the CSV file for passwords . Once you've done that, your browsing experience on Windows will be very similar to what you had on macOS.
6. Photos, email, contacts, calendar, and reminders
Besides documents, we often have a chaotic mess of personal photos, emails, calendars, and tasks scattered across different accounts and services. This data can also be migrated quite cleanly if you choose your tools wisely.
6.1 Photos: From iCloud to your PC (or another cloud)
If you use Apple Photos with iCloud, all your images will be stored in Apple's cloud. From Windows, you can install iCloud for Windows and enable Photos syncing so they are downloaded to a local folder on your PC.
Another strategy is to use your iPhone as a bridge : install Google Photos or OneDrive on your phone, enable automatic photo backup, and let it upload everything. Then, on your PC, install the same application, and your images will be available without needing to touch your Mac.
If you plan to continue using your iPhone and aren't concerned about relying on iCloud, you can simply access iCloud.com from your Windows browser, where you'll see your photos without having to physically move them. It's a convenient solution if you want to minimize changes.
6.2 Mail, contacts and calendar
This section can be extremely easy or a bit more technical, depending on where your data is stored. If you use Gmail, Google Calendar, and Google Contacts , switching from Mac to Windows is seamless: you log in to your browser or Outlook, and everything appears automatically.
If, on the other hand, you use iCloud Mail, Contacts, and Calendars , you have several options. One is to configure your iCloud account directly in a client like Outlook or Thunderbird on Windows, which will handle synchronizing everything via IMAP and CalDAV/CardDAV when available.
Another cleaner long-term option is to migrate your data from iCloud to Google or another service . From Mail and Calendar on macOS, you can connect both accounts and drag and drop messages and events between them. It's a bit more cumbersome, but it leaves you with a more standardized system in the future.
6.3 Reminders and to-do lists
Apple Reminders doesn't offer a convenient way to export them to Windows in bulk , beyond partial integrations. If you have many lists, the most practical approach is usually to rebuild them gradually in a cross-platform app.
Services like Todoist, Microsoft To Do, and Notion work the same on Mac, Windows, iOS, and Android. You can keep both reminder systems running in parallel for a while, and as you complete tasks or create new ones, you can then transfer them to the new platform.
7. Migration of professional projects and files (music, development, design…)
Transferring simple text documents is easy, but when we talk about complex projects —music production, programming, design— another factor comes into play: the software and its versions across platforms.
For example, if you produce music with FL Studio on Windows, you can install the macOS version and open your projects on your Mac without major issues, provided the plugins and libraries are also available. Conversely, if you were producing on a Mac and now switch to Windows, the approach is the same: install the same version of FL Studio and check for plugin compatibility.
In general, cross-platform software project files (FL Studio, Ableton, Visual Studio Code, web projects, etc.) are compatible across systems as long as you respect versions and dependencies . What changes is how you access them: via external drive, NAS, or cloud storage.
If you had your sessions, samples, or resources on an external hard drive, make sure it's formatted as exFAT so you can use it on both Mac and Windows. Copying those assets to a cloud service like OneDrive or Google Drive will also give you the freedom to access them on any machine, though you'll need to keep an eye on the available storage space.
In development environments, Windows offers several alternatives to Xcode, such as Visual Studio and Visual Studio Code . VS Code, in particular, works almost identically on both systems, and if you sync your settings (JSON settings, extensions), you'll have your editor with the same look and shortcuts on both macOS and Windows.
8. Practical differences between Mac and Windows in day-to-day work
Beyond simply moving files from one place to another, there are several changes in habits you'll notice when switching from Mac to Windows . Knowing them beforehand will save you a lot of frustration during your first week.
The first is how apps are managed: on macOS, closing the window (red button) doesn't always close the application, which usually remains active until you press Cmd+Q. On Windows, pressing X normally closes the entire program. It's a minor detail, but it causes confusion.
The second major change is in the file manager . Finder and Windows Explorer share a similar philosophy, but differ in aspects like the address bar, path handling, and file movement. On a Mac, there isn't a true "Cut" function; you copy files and then "paste" them by moving them. On Windows, cutting and pasting are more straightforward with Ctrl+X and Ctrl+V.
Many keyboard shortcuts are also changing: where you used Cmd, you'll now use Ctrl . Copying is Ctrl+C, pasting is Ctrl+V, closing the window is Ctrl+W… and so on for almost everything. The Windows key opens the Start menu and serves as the base for many useful shortcuts (Windows+D to show the desktop, Windows+E for File Explorer, Windows+L to lock your session).
When it comes to installing programs, on macOS you're used to dragging apps to the Applications folder or using the App Store . On Windows, the usual method is to download an .exe or .msi file from the official website and follow the wizard. There's also an official store (Microsoft Store) and a more advanced package manager (WinGet), but most users still download the installer from the developer's website.
9. Migration and backup tools
Although here we focus on going "manually" from Mac to Windows, it doesn't hurt to know the official tools that exist to migrate between Macs and from Windows to Mac , in case at some point you go the other way or use a PC as a bridge.
Apple includes Migration Assistant in macOS , designed primarily for transferring data from one Mac to another (or from Time Machine backups) and also for bringing information from a Windows PC to a Mac. It doesn't work for migrating from Mac to Windows, but it does give you clues about the types of data that need protection: user accounts, documents, music, photos, email, settings, etc.
If you switch back to macOS in the future, you can use this Migration Assistant by connecting both computers via Wi-Fi or, even better, via Ethernet or Thunderbolt cable. The system will take care of putting everything back in its place, although you'll have to reinstall your apps.
In any case, when you're going to make such a major system change, it's highly recommended to create a complete backup of your Mac , for example, using Time Machine on an external drive. Even if everything seems to have gone perfectly, knowing you can recover any files you might have missed provides great peace of mind.
You can do something similar in Windows once you finish your migration: set up File History, backups to OneDrive, or a system image so you don't have to start from scratch if something goes wrong in the future.
Ultimately, switching from Mac to Windows involves more organizing accounts and services than simply moving gigabytes of data. If you store your files in a cross-platform cloud service, properly export your Apple documents, migrate your bookmarks and passwords, and review your photos, email, and contacts , the rest is just adapting to new shortcuts, menus, and ways to install programs—something you'll master in a few days, allowing you to work comfortably on your new PC without missing your old Mac files.
