Changelog

New: OneDrive Support

Driio now supports Microsoft OneDrive. Browse, download, upload, and manage your OneDrive files directly in Finder and the iOS Files app — with the same native integration as every other protocol.

• Powered by the Microsoft Graph API — the same API used by the official OneDrive clients
• Secure OAuth sign-in via Microsoft's identity platform — your password is never stored
• Tokens stored in iCloud Keychain and synced across your devices
• Chunked uploads for large files via Microsoft Graph upload sessions
• Available on both macOS and iOS

New: NFS Protocol Support (NFSv3)

Driio now supports NFS (Network File System) — the standard protocol for Unix and Linux file sharing. Connect to NFS exports from Linux servers, FreeBSD, Synology, QNAP, TrueNAS, and other NAS devices.

• NFSv3 protocol with connection pooling for parallel transfers
• Optional UID/GID override for AUTH_SYS authentication
• Available on both macOS and iOS

New: Network Restore Recovery

File Provider domains are now automatically recovered when your network connection is restored. If a connection drops and comes back, Driio re-registers it without manual intervention.

Bug Fixes

• Fixed deleted subfolders getting stuck on "Loading" in Finder — the polling registry now releases a folder's path as soon as it is deleted, so stale subtrees no longer linger after a successful delete
• Fixed SSH/SFTP uploads being reported as "stalled" after already finishing — the transfer watchdog now gives the post-upload verification step its own budget and treats any progress callback as activity

New: TLS Certificate Flexibility

Connections to self-hosted servers with self-signed certificates previously failed with an untrusted certificate error. A new "Allow Untrusted Certificates" toggle is now available for WebDAV, S3, and FTP connections.

• Toggle located in the Advanced section of each connection editor (macOS and iOS)
• Off by default — enable only for servers you trust that use self-signed or private CA certificates
• Setting syncs across devices via iCloud

New: SSH Host Key Verification

SSH connections now verify the server's identity on every connection using Trust-on-First-Use (TOFU) — the same model used by OpenSSH.

• First connection captures the server's host key fingerprint automatically
• Subsequent connections verify the fingerprint — if the server's identity changes unexpectedly, the connection is blocked
• Verified fingerprint is shown in the connection editor and syncs to all your devices via iCloud
• Existing connections will verify on next save — a notice in the editor lets you know when a connection hasn't been verified yet

Fix: FTP Certificate Verification

FTPS connections now verify server certificates by default, matching the behavior of all other protocols. Previously, certificate verification was skipped unconditionally for FTP.

New: iOS Support

Driio is now available on iPhone and iPad. Your connections appear in the Files app just like on Mac.

• Browse and manage files on SMB, SSH/SFTP, WebDAV, FTP, S3, and Dropbox — all from the iOS Files app
• Per-device connection control — disable connections that only work on your local network so they don't appear on your phone
• Internal network detection — connections to private IPs are labeled "Local Network" so you know which ones won't work away from home
• Error history — see the last 10 errors per connection to diagnose issues without digging through logs

New: iCloud Sync

Connections now sync across all your devices automatically via iCloud.

• Add a connection on your Mac and it appears on your iPhone (and vice versa)
• SSH keys sync via iCloud Keychain — generate once, use everywhere
• Passwords and OAuth tokens sync via iCloud Keychain
• Per-device enable/disable is intentionally NOT synced — each device controls its own set

Improvements

• Faster startup — deferred keychain diagnostics and iCloud sync off the main thread
• Better Finder integration — credential changes now automatically reset the File Provider domain so Finder picks up the fix immediately
• SSH key manager — shows a clear warning when a private key is missing instead of silently failing
• OAuth sign-in — completing sign-in now persists immediately without needing to hit Save
• App launch — clicking the app icon now always shows the main window, even when running as a menu bar item
• License check — the dashboard loads first while StoreKit resolves entitlements
• Connection pool stability — fixed shutdown hangs, WebDAV idle connection leaks, and enumerator cache cleanup

Bug Fixes

• Fixed "Syncing Paused" deadlock in iOS Files app
• Fixed iCloud connection deletion sync (was additive-only, never removed deleted connections)
• Fixed SSH key sync issues across devices
• Fixed connection pool shutdown hangs and WebDAV idle connection leaks
• Fixed credential warning banners appearing on new unsaved connections

New: Dropbox Support

• Browse, download, upload, and manage Dropbox files directly in Finder
• Real-time change detection via Dropbox longpoll, with configurable fallback polling
• Chunked uploads for large files

Improvements

• Added local storage usage display to the Activity Dashboard
