Your files are scattered across iCloud, Dropbox, Google Drive, and OneDrive – and each service guards its storage quota like a secret. macOS happily shows your iCloud usage in System Settings, but for every other cloud you’re left opening four different apps or websites just to answer a simple question: how much space do I have left? Here’s how to see free space across all your cloud services in one place on your Mac.
Before you start: what macOS shows (and doesn’t)
Apple only reports iCloud storage natively: go to System Settings, click your Apple ID, then iCloud, and you’ll see your usage. Dropbox, Google Drive, and OneDrive don’t report their quotas to macOS at all – their Mac apps sync files but stay silent about free space. That gap is exactly what we’re going to close, using a disk utility that speaks fluent cloud.
How to monitor all cloud storage with DaisyDisk
- Get DaisyDisk. Download it from the official DaisyDisk site – it’s $9.99, but the free trial is fully functional, so you can test everything below before paying.
- Launch DaisyDisk. (If you ever lose it, here’s how to quickly open the installed apps list in macOS 26.) You’ll see your local disks plus a “Scan Folder…” option.
- Connect a cloud service. Click the small triangle next to “Scan Folder…” and pick your cloud service – Dropbox, Google Drive, OneDrive, and others are listed.
- Authorize in your browser. Your browser opens the service’s login page; sign in and grant DaisyDisk read access. The service then appears in DaisyDisk’s sidebar with its free space front and center.
- Repeat for each service. Add Dropbox, Google Drive, OneDrive – each connected cloud shows its remaining space at a glance, and you can even connect multiple accounts of the same service.
- Drill in and clean up. Click any cloud to scan it like a local disk: DaisyDisk’s visual map shows what’s eating space, so you can delete or move the biggest offenders – just like setting up message sync between iPhone and Mac, it’s about linking services so they work together.
The free alternative: per-service dashboards
Don’t want another app? Every cloud service shows your quota on its website – Dropbox, Google Drive, and OneDrive each have a storage page in your account settings (Apple Support covers the iCloud side). It’s free and accurate; it’s just four separate tabs instead of one window. 9to5Mac has covered similar storage-management workflows for Mac users juggling multiple services.
If it still doesn’t work
- Cloud service doesn’t appear – make sure its Mac sync app is installed and you’re signed in; DaisyDisk connects through the service’s API.
- Authorization fails – try again in a different browser or an incognito window; corporate Google Workspace accounts may need admin approval.
- Free space looks wrong – quotas update with a delay after big deletions; wait a few minutes and rescan.
- Trial expired – the trial is fully functional but time-limited; the $9.99 license is a one-time purchase.
Frequently asked questions
Can macOS show Dropbox or Google Drive free space natively?
No. macOS only surfaces iCloud storage in System Settings. Third-party services don’t expose their quotas to the system, which is why a tool like DaisyDisk – or each service’s web dashboard – is necessary.
Is DaisyDisk safe to connect to my cloud accounts?
DaisyDisk uses each service’s official OAuth login in your browser, so it never sees your password, and you can revoke its access anytime from the service’s security settings.
Conclusion
Stop guessing which cloud is full. Connect them all in DaisyDisk and your free space is one glance away – or bookmark the four web dashboards if you prefer the free route. Either way, you’ll never be surprised by a “storage full” error mid-upload again.
