SGF Tools 2.0 is a rewrite from scratch of the Mac tools for SGF (Go game) files, for today's
macOS. It has:
- Thumbnails in Finder: each game's board after the opening moves, with a stack of boards for
a file that holds several games. - Quick Look previews: press the Space bar on a game to see the board beside the players,
the result, the event, the date, and the rest of the game information. - Spotlight search: the players, event, date, result, comments, and more of every game, in
Spotlight, Finder, andmdfind. The fields keep their 1.x names, so old saved searches work. - A screensaver that plays the opening of a random game from your collection on each
display, two moves a second.
Requires a Mac with Apple silicon and macOS 26 or later.
What's new in 2.0.9
A much lighter screensaver. Each move now redraws and fades only the few small areas of the board
that change, instead of the whole board. It looks exactly the same, but on a two-display Mac the
window server's work while the screensaver runs dropped from about 77% of a CPU core to about 28%
(measured over two minutes). The app is unchanged.
Installing
- Download
SGF-Tools-2.0.9.dmg, open it, and drag SGF Tools to Applications. - Open SGF Tools once. The first time, macOS asks whether you want to open an app downloaded
from the internet: click Open. Then runqlmanage -rin Terminal. - For the screensaver: click Update Screensaver Games in SGF Tools and allow the access
requests. DragSGF Tools.saverfrom the disk image to your Desktop, double-click it, and
install it for this user only. Then choose SGF Tools in System Settings > Wallpaper > Screen
Saver (under Other), for each display.
Updating from 2.0.8 or 2.0.7: quit SGF Tools, replace it in Applications, and open it once. To update
the screensaver, run killall legacyScreenSaver in Terminal first, then install the new one.
The disk image's Read Me and the README have the
details, including indexing the games you already have.
