Connect Drive in macOS Finder

macOS has WebDAV support built in, so you can connect TrekMail Drive directly from Finder. Once mounted, your Drive shows up like a network folder in the sidebar — drag files in, double-click to open, edit in place.

Verified on macOS Sonoma 14 and Sequoia 15. Apple's reference: Finder → Go → Connect to Server.

Before you start

You need a device password for the sync app. The password you use to log into the dashboard does not work for sync — sync apps get their own one-time password so you can revoke them individually.

1. Open Sync devices in your TrekMail dashboard.
2. Click + Add new device.
3. Name it (e.g. MacBook — Finder).
4. Leave the default scopes checked: View files and Edit files.
5. Click Generate password and copy the password it shows. You only see it once.

Keep the password tab open while you connect — you'll paste it in a moment.

Connect from Finder

1. In Finder, open the menu Go → Connect to Server… (keyboard shortcut: Command + K).
2. In the Server Address field, paste the Drive server URL shown at the top of the Sync devices page. It looks like https://drive.YOUR-DOMAIN/dav/files/account/ — copy it directly from the banner so the host part is right for your account.
3. Click Connect. macOS asks how you want to connect.
4. Pick Registered User (not Guest), then enter:
   • Name: your account email (the one you use to log into TrekMail)
   • Password: the device password you just generated (starts with dsync_)
5. Check Remember this password in my keychain if you want Finder to reconnect automatically next login.
6. Click Connect.

Finder opens a new window showing your Drive. It also appears in the sidebar under Locations.

Working with files

• Drag files in — they upload in the background. A progress dot appears next to the file name.
• Double-click to open — most file types open in their default app. Save and Finder uploads the changes.
• Right-click → New Folder — works like any folder.
• Move to Trash — moves the file to Drive's trash (you can restore it from the dashboard for 30 days).

Large files are uploaded in chunks automatically — no separate setting needed. There is no file-size cap — drag in 100 GB videos or full disk images and Finder handles them like any other file (give them time on slower connections; Finder shows progress in the bottom strip).

Reconnecting after restart

macOS forgets WebDAV mounts on restart by default. To make Finder reconnect:

1. Mount Drive once (steps above).
2. Open System Settings → General → Login Items & Extensions → Open at Login.
3. Click the + button and pick your mounted Drive from the Network group.

The mount will then re-establish on every login (you'll still need to authenticate the first time after a password change).

Troubleshooting

• "There was a problem connecting" — double-check the URL has https:// (not http://) and ends with /dav/files/account/ including the trailing slash.
• "The name or password is incorrect" — use the device password, not your dashboard password. Make sure you copied the full dsync_... string with no trailing space.
• Uploads are slow / Finder beachballs on big files — Finder's WebDAV client is single-threaded, so multi-gigabyte transfers monopolise one connection at a time. The file will arrive eventually (no size limit), but if you want parallel uploads and resume-on-disconnect, rclone or Cyberduck finish the same job much faster.
• Some files don't appear — Finder caches aggressively. Right-click the Drive in the sidebar, pick Eject, then reconnect from Go → Connect to Server….
