Changelog

New: Share Files from Finder

Create share links and manage who has access to a file without leaving Finder. Right-click any file on a supported connection and you’ll find two new actions: Copy Share Link and Manage Sharing.

• Copy Share Link: create a public link to a file and copy it to your clipboard in one click. Works with Nextcloud, OneDrive, Dropbox, and Amazon S3. (S3 links are presigned and expire after 7 days.)
• Manage Sharing: see every share on a file (public links and the people or groups it’s shared with, marked view or edit), revoke any of them, or share with a specific person. Recipient search with email fallback, plus Allow-editing and Notify-recipient toggles.
• Sharing shows up only where it works: Driio checks each connection’s capabilities and hides the menu items on connections and files that don’t support it.
• A confirmation panel reminds you whenever a link makes a file publicly visible.

New: Share Links on iPhone & iPad

Sharing comes to iOS through the system Share sheet. Select a file on a supported Driio connection, tap Share, and choose Driio Share Link to create a public link and copy it in a single tap.

• Same connections as the Mac: Nextcloud, OneDrive, Dropbox, and S3.
• Lives in the Share sheet rather than the Files context menu. (On iOS the Files menu can’t tell Driio which item you picked; the Share sheet hands over the file directly, so it just works.)

Improvements

• Fresher browsing: the folder you’re looking at is checked for changes first on every refresh, and stepping into a folder that Finder drew from its own cache kicks off a quick freshness check, so changes made on the server show up sooner. Listings you navigate away from now cancel cleanly instead of tying up a connection.

Bug Fixes

• Fixed the Stop button in Files/Finder not actually cancelling a download. On SMB, Nextcloud/WebDAV, OneDrive, and FTP the transfer used to keep running to completion in the background. Cancelling now stops the download immediately on every protocol, with no leftover error, even when the file was being opened or previewed at the same time, which used to leave a stray “could not download” alert.
• Fixed quick folder-to-folder navigation on WebDAV and cloud connections occasionally dropping the connection with a spurious “Cannot Connect” banner. Clicking away from a folder before its listing finishes is normal, and is no longer mistaken for a connection failure.

New: Diagnostic Logging

When something goes wrong with a connection, you can now turn on detailed logging and send the resulting file when reporting an issue. Logging is off by default in release builds, and the log writes to the shared app group container so it survives between launches.

• Toggle on under Advanced → Diagnostics on macOS, or Settings → Troubleshooting → Diagnostics on iOS
• Off by default in release builds, so there’s no overhead until you turn it on

Improvements

• Clearer SMB error messages: connection and browse failures now explain what actually went wrong instead of showing a generic “The operation couldn’t be completed” alert. Wrong credentials, missing shares, permission denials, and unsupported protocol versions each get a specific message, and a server that only speaks SMB1 (such as legacy Samba) now says so instead of being misreported as a bad password. Lower-level network failures (connection refused, host unreachable, DNS, TLS) are reported honestly too.
• Automatic log rotation: the current log rolls over once it passes your size limit (default 10 MB), and older copies are dropped past the keep count (default 4 files), so logs never grow unbounded.
• View logs without leaving the app: Show Logs in Finder on macOS opens the logs folder, and Share Logs on iOS exports the current log and any rotations via the system share sheet.
• Less intrusive review prompt: the App Store review request now appears only after you’ve actually used the app, waiting for a first-use grace period, a few successful transfers, and a polite interval before asking again.

Bug Fixes

• Fixed SMB shares on macOS getting permanently stuck after a brief network problem. A single failed directory listing (a timeout, dropped connection, or a server briefly unreachable after sleep or a network change) used to disconnect the share in Finder with no retry. Transient failures no longer disconnect the share, and any share left stuck by an earlier version reconnects the next time you open Driio.

Bug Fixes

• Fixed large downloads from WebDAV (including Nextcloud) and OneDrive failing with a false “Transfer stalled - no progress for 30 seconds” error. The download was streaming at full speed the whole time, but the URLSession progress callbacks were being silently suppressed, so the stall watchdog never saw the byte counters. Affected any file that took longer than 30 seconds to download, regardless of network speed.
• Fixed chunked uploads to WebDAV (Nextcloud) and OneDrive falsely stalling on slow upload links. Per-chunk progress is now reported continuously instead of only at the end of each 5 to 10 MB chunk, so a single chunk taking longer than 30 seconds no longer fails the whole transfer.

New: OneDrive Support

Driio now supports Microsoft OneDrive. Your OneDrive files show up in Finder and the iOS Files app the same way every other protocol does.

• Uses the Microsoft Graph API (the same one the official OneDrive clients use)
• 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, the standard file-sharing protocol on Unix and Linux. Connect to 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's deleted, so stale subtrees don't linger after a successful delete.
• Fixed SSH/SFTP uploads getting reported as "stalled" after they'd already finished. The transfer watchdog now gives the post-upload verification step its own budget and counts 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. Turn it on 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 connect. Same Trust-on-First-Use model OpenSSH uses.

• 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 verify on next save. A notice in the editor flags any connection that 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 from the iOS Files app
• Per-device connection control. Disable connections that only work on your local network so they don't clutter your phone.
• Internal network detection. Connections to private IPs get labeled "Local Network" so you know which ones won't work away from home.
• Error history. The last 10 errors per connection are kept around so you can diagnose 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
