Release history.

AI opponents on the desktop board

• Added the dedicated Play window for human vs AI games on Mac.
• AI opponents now use named profiles with stable personality and controlled randomness instead of a scattered difficulty-only setup.
• New games store the opponent snapshot and seed, so continuing a game keeps the same opponent behavior even after profiles change.
• The Mac play board can ask the native KataGo engine for opening and current-position candidates, including empty-board turn 0.

This release brings the new opponent-profile play experience to Mac and keeps the engine path local-only.

Minimum system

macOS 14.0 or later, Apple Silicon.

Localization polish

• Fixed Mac language fallback so unsupported system languages now show GoReview UI in English instead of falling back to the development source language.
• Added per-string English fallback when a supported language is missing a newer Mac string.
• Localized the Mac problem-session summary and added a guardrail to prevent new hard-coded Chinese strings in Mac source.
• Improved regional Chinese language matching for Traditional and Simplified Chinese system preferences.

This is a small Mac 1.4 reliability update focused on language selection and visible localization consistency.

Minimum system

macOS 14.0 or later, Apple Silicon.

Stability and Mac polish

• Fixed a Mac analysis failure when SGF files encode pass moves with older off-board notation.
• Fixed iCloud backup export for deep game trees so automatic sync no longer crashes while encoding game details.
• Separated development builds from the public app identity, so local debug URLs no longer open the installed public app.
• Refined Mac authoring and review UI: larger authoring window, grouped Engine and Authoring toolbar menus, sticky problem-review actions, board-visible metadata editing, and completed Advanced iCloud controls.

This update keeps the Mac 1.4 pro-tools release line focused on reliability before broader rollout.

Minimum system

macOS 14.0 or later, Apple Silicon.

Pro Tools Edition

New on Mac, catching up to iOS 1.4:

• Author your own multi-move problems from mistakes, with AI prefill, replace-first-move editing, failure branches, per-node comments, and keyboard-driven review.
• Drag-and-drop Tygem `.gib` files into the library and import them alongside SGF.
• Branch any analysed position into a fresh authored problem.
• Rate tree problems with SRS from the Mac solver.

Mac-only pro tools:

• Engine Profiles let you save named KataGo configurations for quick, standard, deep, and endgame analysis.
• Deep Analysis can re-analyse a position with higher visits and save snapshots for comparison.
• Batch Analysis Queue lets you queue many games and track pending, running, completed, and failed jobs.
• Compare Games opens two boards side by side with synced scrubber controls and first-divergence detection.
• Library Power Operations add multi-select, bulk tags, ZIP export, delete confirmation, inline metadata editing, and structured search such as `result:B+ tag:tournament`.

Also included:

• OGS token refresh improvements.
• Clearer review terminology.
• Deeper SRS feedback shared with the iOS 1.3 and 1.4 line.
• Deep Analysis cancel and unsupported-SGF handling are more robust, so cancelled or invalid engine runs no longer surface stale KataGo errors.
• Library search now matches player names and ranks even when a game title does not include them.

Minimum system

macOS 14.0 or later, Apple Silicon.

What's new

• **Learning features are now on Mac**: browse your saved problems by category, review what is due today, and solve positions directly in the Mac app.
• **Save mistakes from analysis**: after a completed review, turn detected mistakes into reusable problems without switching to iPhone.
• **Dedicated Study Session window**: run a focused Due Today sweep in a separate window with keyboard-driven rating shortcuts.
• **iCloud problem sync works end to end**: mistakes and SRS state saved on iPhone now appear on Mac through the existing shared database and sync pipeline.
• **Shared problem logic with iOS**: Mac now uses the same problem-solving and SRS session view models as iOS, so verdict and scheduling behavior stay aligned.

Minimum system

macOS 14.0 or later, Apple Silicon.

What's new

• **Unlimited library and analysis on Mac**: GoReview Mac now runs as premium by default. No 500-game storage cap, no monthly analysis quota. Review as deeply as your Apple Silicon can go.

The iPhone and iPad apps keep their existing storage and analysis tiers for now. Paid learning features are in planning and will be their own subscription when they ship.

Minimum system

macOS 14.0 or later, Apple Silicon.

Bug fixes

• **OGS link survives app restart**: relaunching GoReview no longer silently clears your OGS account. Auto-restore from iCloud is now opt-in via the Sync panel.
• **"Sync with OGS" menu item now visible**: the `Sync → Sync with OGS` menu (Cmd-Option-S) correctly appears in the main window menu bar. Previously it was attached to the wrong scene and never showed up.
• **Main-window Sync panel now includes OGS**: the Sync toolbar button opens a panel with OGS account, auto-sync controls, and Sync Now on top, with iCloud backup controls below. No more jumping into Settings just to sync OGS.
• **Accurate manual sync feedback**: manual "Sync Now" now distinguishes between "imported N new games" and "no new finished games to sync". Successful sync with zero new games no longer shows a misleading success toast.
• **Broken OGS links surface clearly**: if the stored OGS credentials have gone bad, pressing Sync Now invalidates the link and prompts you to reconnect, instead of pretending to succeed.

Minimum system

macOS 14.0 or later, Apple Silicon.

What's new

• **OGS sync on Mac**: link your OGS account from the new Settings window (Cmd-,), and GoReview keeps your finished games in sync automatically. The same library shows up across your Mac, iPhone, and iPad.
• **One-shortcut manual sync**: Cmd-Option-S or the new `Sync → Sync with OGS` menu item pulls the latest finished games from OGS on demand.
• **Configurable sync frequency**: pick how often GoReview checks OGS in the background — every 15 minutes, 30 minutes, every hour, or every 6 hours. Defaults to 30 minutes.
• **Energy-friendly background sync**: respects macOS App Nap and battery state, so it never gets in the way of other work.

Quality of life

• New native macOS Settings window with a dedicated Accounts tab (Cmd-,)
• Session expiration now surfaces as a non-intrusive banner in the main window, with one click to reconnect
• Network drops are handled silently — GoReview won't nag you when Wi-Fi is off

Minimum system

macOS 14.0 or later, Apple Silicon.

Branded installer and OGS sync reliability

• GoReview Mac now ships with its own app icon; Dock, Launchpad, and Finder no longer show the generic macOS placeholder.
• Redesigned DMG installer with a drag-to-Applications target and a Retina-sharp window background.
• Manual OGS sync no longer silently "succeeds" when a credential is missing; stale link state is cleaned up so you can reconnect without restarting the app.
• Added an Automatic OGS Sync toggle in Settings to keep the account linked while pausing background syncs.

iCloud sync reliability

• Large game libraries now back up reliably.
• Failed backups automatically retry until they succeed.
• Fixed a stack overflow crash when restoring backups with deep SGF trees.
