Why Mounting Proton Drive on macOS Is a Smart Move
Proton Drive is built around end-to-end encryption under Swiss privacy law, so your files are encrypted before they leave your device. Mounting it on macOS means those files show up in Finder and stream on demand, letting you work on them like local files while the privacy model stays intact.
- 🗂️ Native Finder Access -- Browse your Proton Drive files as a normal macOS volume from any app.
- 💾 No Full Sync Required -- Stream only the files you open instead of mirroring your whole drive to disk.
- 🔁 Live Two-Way Access -- Files dropped into the mount upload to Proton Drive; remote changes appear after the next poll.
- 🛡️ Read-Only Safety -- Browse an archive read-only to avoid accidental edits.
- 🔐 End-to-End Encrypted -- Proton Drive encrypts your data under Swiss jurisdiction, so privacy is part of the storage itself.
How Mounting a Cloud Drive Works (and Why It's Different from Sync)
Sync downloads every file to your Mac and keeps both ends matched. A mount leaves files on Proton Drive and streams them to your Mac only when you open them.
OurClone handles reads, writes, and change detection through a local cache, keeping recently used files fast while the rest stays in the cloud until needed.
You can mount Proton Drive with a configurable polling interval and cache size, plus a read-only option for safe browsing.
- 🚀 Stream files on demand — no need to download the whole drive
- 💾 Saves Mac disk space by caching only what you actually open
- 🔁 Two-way sync — edits in the mounted folder push back to Proton Drive
- 🛡️ Read-only mode prevents accidental writes when you only need to browse
What to Know Before You Mount Proton Drive
Plan these before mounting.
- 🧩 Install macFUSE First -- OurClone's macOS mount relies on macFUSE; install it once before mounting Proton Drive.
- 🔑 Have Your Proton Credentials Ready -- Proton Drive connects with your Proton account email and password; if two-factor is enabled, have your current 2FA code handy.
- ⏳ Allow for Key Initialization -- Because Proton Drive is end-to-end encrypted, the first connection may take a moment to set up keys.
- 🖥️ Choose a Sensible Mount Point -- Use a dedicated empty folder like
~/CloudMounts/ProtonDrive, not your Desktop or a populated folder. - 🔒 Read-Only vs Read-Write -- Read-only suits browsing; read-write is needed to upload, edit, or delete. Read-only mounts can't upload.
- 💽 Plan Your Cache Size -- A larger cache speeds repeat access but uses local disk; size it to the files you open most.
How to Mount Proton Drive on macOS with OurClone
OurClone connects to Proton Drive with your account credentials, then mounts it as a local volume.
- 🔗 Add Proton Drive with Your Account Credentials -- Open OurClone and go to
Add Storage. Select Proton Drive. Enter your Proton account email and password directly in OurClone; if you use two-factor authentication, enter your current 2FA code. The first connection may pause briefly to initialize encryption keys, then Proton Drive is added. - 📂 Open the Mount Tab and Click New Mount -- With Proton Drive connected, go to the
Mounttab and click New Mount in the top-right corner. - ⚙️ Configure the Mount Settings -- Pick Proton Drive as the source. Choose a specific folder or the whole drive, then a local mount point like
~/CloudMounts/ProtonDrive. Select Read-only or Read-write, optionally adjust polling interval and max cache size, and click Mount. - 🗂️ Use Your Proton Drive Mount Like a Local Folder -- Open the mount point in Finder. It behaves as a mounted volume — browse, open, create folders, drag in files, and delete items. Add a
backupfolder and a few files; OurClone streams them to Proton Drive in the background. - ✅ Confirm the Sync on Proton Drive -- Back in OurClone, open the Proton Drive storage in the file browser to see the new
backupfolder. For extra certainty, log in to the Proton Drive web app and confirm the files arrived.
Account credentials plus OurClone's mount engine turn end-to-end-encrypted Proton Drive into a native-feeling drive on macOS.
Getting the Most Out of Your Proton Drive Mount
Keep these in mind once your Proton Drive mount is live.
- 🔁 Edits Sync Both Ways -- Adds, renames, and deletes in the mount push to Proton Drive; changes from other devices appear after the next poll cycle.
- 🛑 Read-Only Means Read-Only -- A read-only mount blocks uploads and saves. Remount read-write to make changes.
- 💽 Cache Lives on Your Mac -- Recently opened files are cached locally; lower the max cache size if disk space is tight.
- ⏱️ Polling Interval Affects Freshness -- For Proton Drive, a 30–60 second interval usually balances freshness against API calls.
- 🔌 Unmount Cleanly Before Sleep -- OurClone reconnects on wake; for long breaks, click Unmount to release the volume.
When Your Mount Stops Working
Proton Drive mounts usually break when the account password changes, two-factor settings are updated, the network drops, or the mount point is no longer empty. Re-enter your credentials (and a fresh 2FA code), then remount.
Verify the Sync Anytime
When in doubt, open the Proton Drive storage view inside OurClone or sign in to the Proton Drive web app to confirm your files.
