## What is uSSH?

Live updates in Finder and Files
Remote folders now refresh on their own. A small signed helper, ussh-fsmonitor, runs on the host over the existing SSH connection and streams changes back; uSSH installs and upgrades it for you and verifies every copy against a key published in a DNSSEC signed DNS TXT record. It watches only the folders you have open, so a busy home directory costs nothing, and the extension keeps a feed alive briefly even when the app is closed. Resync Now really resyncs, deletions reach Finder, and root@ bookmarks can opt in.

Paste safety
Right-click paste, and a confirmation before any multi-line paste. A built-in rule set flags dangerous commands, and on Apple-silicon devices the on-device model reviews the clipboard and streams its verdict into the sheet, with a red Paste button when the risk is high. A quiet mode lets routine pastes through while still holding anything the model dislikes.

Find in scrollback
⌘F searches the scrollback of shell tabs and tmux panes alike, on Mac and iPad. In tmux it can escalate into the pane's full server-side history, and the local scrollback follows the pane's own history limit.

tmux across devices
Shared sessions get a size lock with ownership: the first device to lock a window keeps its size, others see a scaled view instead of fighting over the grid. Session names are per device, and closing a session's last window no longer disconnects you.

Selection
Option-drag block selection on the Mac for copying columns out of TUI panels. Shift-drag selects text even inside mouse-aware programs such as btop or tmux with mouse mode on.

Keys and trust
Passphrase-protected OpenSSH keys import directly. DNSSEC trust aot key rollovers the RFC 5011 way, so validation keeps workingacross the October rollover without an update, and the pre-connect terminal log narrates every DNSSEC and SSHFP step.

Finder and Files locations
Symlinks are followed on the server, so linked folders such as /ookmarks mount read-only by default with a per-bookmark override.

Bookmarks
ShellFish-compatible CSV import and export, Duplicate in the context menu, a keyboard-driven launcher filter, and a status bar that shows scrollback size and
memory.

Fonts on iOS
Import TrueType and OpenType fonts from Files, with a verbatim preview, and a font floor of 6 pt for dense layouts.

Diagnostics
A production debug log you can share from Settings, now including log.

## Version history (last 5 releases)

### 1.5.2 — 2026-09-13

Bugs have been fixed in the theme selector and in the way the mac version handles overflow of connections in single window mode.

### 1.5.1 — 2026-09-10

1. Agent forwarding, per bookmark. Turn on "Forward the SSH agent" and programs on that host, such as git, ssh to a second hop, or a deploy script, can use your keys through the connection, like ssh -A. Every request a remote program makes is approved on your device first, and the prompt says which host asked, which key, which account it is authenticating as, and which server it is going to. In tmux sessions the forwarded agent keeps working after you reconnect.

2. Drop files and screenshots into a session. Drop a file on a terminal, or paste a screenshot into it, and uSSH copies it to the host and types its path, exactly what a program like Claude Code expects from a drag. Copied files paste the same way. On iPad, drop from Files or Photos.

3. Review pastes with your own model. Point the paste check at a model server you run, such as Ollama, LM Studio, or any OpenAI-compatible endpoint, instead of the on-device model, with a picker for the server's models, a wait budget, and a Test button. Off by default; only the paste under review is sent, only to that server.

4. Paste guard catches assembled commands. A command built from string slices or hex escapes, the classic way to hide rm -rf inside innocent words, is now flagged by the deterministic rules, whatever a model says.

5. iTerm2-style pane shortcuts. A setting adds iTerm2's keys to tmux windows: ⌘D and ⇧⌘D to split, ⌥⌘-arrows to move between panes, ⌘] and ⌘[ to cycle, ⇧⌘Return to maximize, ⇧⌘] and ⇧⌘[ for tabs.

6. Clearer tmux panes. The pane that takes your keystrokes is unmistakable: inactive panes show a dimmed, blinking underline cursor, and so does the whole terminal when uSSH is not the front app. Clicking a pane always moves the keyboard there, and every pane's scrollbar is reachable.
