Why Drive Crazy

One drive to rule every cloud.

Stop juggling browser tabs and sync folders. Mount your storage once and work with it natively.

🗂️

Native mounting

Your cloud appears right in Finder and File Explorer. Double-click, drag, drop — no browser, no uploads.

⚡

Stream, don't sync

Files open on demand instead of downloading everything. Access terabytes without filling your disk.

🌐

Universal by design

Built to speak to many clouds. Add a new provider and it mounts alongside the rest — one consistent workflow.

🔒

Secure sign-in

Authenticate through your provider's official login. Drive Crazy connects on your behalf — your credentials stay with them.

A true desktop app on macOS today, with Windows right behind it — the same drives on every machine you use.

Any app that opens files can open cloud files — Office, Adobe, editors, scripts. It's just a drive.

Disk image for macOS 13 Ventura or later · all versions

Installing

  1. Open the disk image and drag Drive Crazy into Applications, then open it from there.
  2. macOS will say it cannot verify the developer: the app is signed but not yet notarized with Apple. Open System Settings → Privacy & Security, scroll to the message about Drive Crazy and click Open Anyway.
  3. Sign in with your Microsoft work or school account, choose a Teams or SharePoint folder, and it appears in Finder's sidebar under Locations. Click Enable on Finder's banner the first time.

Nothing is synced to your disk. Settings has an Uninstall button that removes the drives, sign-ins and the app.
