How to Check OneDrive Storage Usage on a MacBook Pro
Question details
The user needs to find out how much OneDrive cloud storage space is currently used and how much is still available on a MacBook Pro.
- Product
- Microsoft OneDrive
- Device & OS
- macOS
- Scenario
- Verifying cloud storage capacity and managing space limits for a Microsoft 365 Family account.
- Observed behavior
- Using Finder's 'Get Info' displays the local file size on the disk rather than actual cloud usage, which creates discrepancies when the Files On-Demand feature is active.
Ensure your Mac is connected to the internet and that the OneDrive desktop application is running, or have your Microsoft account credentials ready to sign in via a web browser.
Check Storage via the OneDrive Web Portal
Using the web portal is the most accurate way to view your total cloud storage usage and manage large files, completely bypassing local Mac storage settings.
Because the macOS Finder only calculates the space files take up locally on your hard drive, checking your storage directly on the OneDrive website guarantees you are seeing the true server-side usage.
Open your preferred web browser on your MacBook Pro, navigate to the official OneDrive website, and sign in with your Microsoft account.
Click on the gear icon (Settings) located in the top-right corner of the screen.
Select 'Options' or 'Storage metrics' from the menu. Here, you will see a detailed bar chart displaying your used storage, available space, and a breakdown of what is taking up space.
Check Storage via the Mac Menu Bar
You can quickly check your storage directly from your Mac desktop using the OneDrive application icon in the menu bar.

Frequently Asked Questions
Why does Mac Finder show a different OneDrive file size than the web?
When the OneDrive 'Files On-Demand' feature is turned on, your Mac only stores placeholder files locally until you open them. Finder measures this tiny local footprint, whereas the web portal shows the actual full size of the file stored on Microsoft's servers.
How can I free up space on my OneDrive account?
You can free up space by deleting large, unneeded files, emptying the OneDrive Recycle Bin on the web portal, or removing older versions of documents through the version history feature.
Can I increase my OneDrive storage limit on my Mac?
Yes. While you cannot change the limit through your Mac's system settings, you can purchase additional storage or upgrade your Microsoft 365 subscription directly through the OneDrive web portal under 'Manage storage'.
What happens if my OneDrive storage becomes completely full?
If you reach your storage limit, OneDrive will stop syncing files across your devices. You will not be able to upload or edit files saved in OneDrive until you delete existing files to free up space or upgrade your storage plan.
