Mount OneDrive for Business on macOS — NetDrive Setup Guide

A marketing consultant running macOS splits work across two Microsoft 365 tenants — her agency’s and a client’s. The OneDrive sync client forces a separate local folder per account, each pre-downloading gigabytes of files she may never open. NetDrive takes a different path: both OneDrive for Business accounts appear as volumes in Finder, files stream on demand, and nothing lands on the local SSD unless she explicitly opens or downloads it.

Mount OneDrive for Business directly in macOS Finder

NetDrive lets Google Drive, OneDrive, S3, SFTP, WebDAV and more appear as native drives on Windows and macOS — no syncing, no full downloads.

• Access your full OneDrive for Business library as a native /Volumes/ entry
• Stream files on demand — no local copy until you open or download
• Works with macOS 14 Sonoma on Intel and Apple Silicon Macs

OneDrive for Business vs. Personal OneDrive

OneDrive for Business is the enterprise document store tied to a Microsoft 365 work or school account — backed by SharePoint and governed by your organization’s IT admin. Its authentication runs through Azure AD OAuth rather than a Microsoft personal account flow, which is why adding it in NetDrive looks slightly different from adding a personal OneDrive.

NetDrive has supported OneDrive for Business since version 3.1.196. If you need both a personal OneDrive and a work OneDrive for Business account on the same Mac, add them as two separate drives in NetDrive — each gets its own volume name in Finder.

macOS version note: NetDrive 3.18 requires macOS 14 Sonoma or later. If you’re still on macOS 13 Ventura, NetDrive 3.17 is the latest compatible version and supports OneDrive for Business with the same setup steps below.

Requirements

• macOS 14 Sonoma or later (Intel or Apple Silicon)
• A Microsoft 365 work or school account with OneDrive for Business enabled
• NetDrive 3.19.7 — download the DMG installer at https://www.netdrive.net/download/mac/

After installation, NetDrive lives in the macOS menu bar. A 7-day free trial starts automatically — no credit card required.

Adding OneDrive for Business in NetDrive

1. Click the NetDrive icon in the menu bar to open the Drive Manager.
2. Click + Add Drive.
3. In the provider list, select OneDrive for Business.
4. NetDrive opens your default browser to the Microsoft login page. Sign in with your work or school Microsoft 365 credentials.
5. If your tenant requires MFA or conditional access (Intune compliance, named-location policies), complete the challenge in the browser — NetDrive waits for the OAuth redirect to finish.
6. Back in NetDrive, configure the drive:
   • Drive Name: Give the volume a display name, such as Work-M365 — this is what appears in Finder’s sidebar under Locations.
   • Mount Type: Choose Network Drive for full read-write access, or Read-only Drive for a no-edit view of the library.
7. Click Save, then click ▶ Connect on the drive card.

The volume appears in Finder’s sidebar within a few seconds.

Day-to-Day Use from macOS Applications

Once the volume is connected, any macOS app sees it through Finder’s standard Open and Save dialogs. Open a Keynote deck from /Volumes/Work-M365/Marketing/Deck.key directly in Keynote, edit it, hit ⌘S — NetDrive uploads the saved file to OneDrive for Business in the background while you keep working.

The mounted volume shows up in Finder’s Locations sidebar alongside iCloud Drive and any external drives, so the workflow for finding files is the same as with a local disk. Spotlight search indexes the volume names and can find filenames across the mounted OneDrive for Business library without any additional configuration.

If you open a Microsoft Office file from the mounted drive in Office for Mac, NetDrive’s file-locking support (added in version 3.9.1190 for all file types) prevents conflicting edits when a colleague opens the same document. The file shows as read-only for the second opener until the first user closes it — the same behavior you’d expect from a shared file server, except the backend is your organization’s Microsoft 365 tenant.

Auto-Mount on Login

Set Auto Mount to On Login in the drive’s settings so the OneDrive for Business volume reconnects automatically every time you log in to macOS. Credentials are stored in the macOS Keychain, so the reconnection is silent and requires no password entry.

For consultants working across multiple client tenants, each tenant’s OneDrive for Business account can be added as a separate drive with its own volume name. All of them reconnect on login without intervention.

Wrap-up

Mounting OneDrive for Business on macOS with NetDrive removes the sync agent entirely. Your full Microsoft 365 library is accessible from Finder the moment the drive connects, files stream on demand rather than filling your SSD, and uploads run in the background without interrupting your workflow.

For Windows counterparts on the same Microsoft 365 tenant, Mount OneDrive for Business on Windows with NetDrive covers the same OAuth flow with drive-letter assignment instead of Finder volumes. If your organization also uses SharePoint document libraries beyond OneDrive for Business, those connect through NetDrive’s SharePoint provider — see Mount SharePoint on macOS with NetDrive for that setup.
