uFits 0.0.7

uFits shows FITS and XISF files in Finder: Quick Look previews (select a file, press
Space) and thumbnails for images, cubes, tile-compressed .fz files, spectra, light
curves, catalogs and tables, with every header.

New in 0.0.7

• A new icon: a galaxy in pixel art, in two looks, Dusk and a light one. On macOS 26
  uFits shows the light icon, and Dusk when System Settings › Appearance › Icon & widget
  style is Dark; on macOS 15 and earlier, Dusk.
• App icon in the uFits app: Automatic, or always Dusk, or always the light icon. The
  Dock and the app's window show the one you choose, and updates keep it.
• A homepage that shows uFits at work: lmytime.github.io/uFits.

From 0.0.3 on, uFits says when a newer version is out (Update available in the
preview's bar) and updates itself when you open it. From 0.0.2 or earlier, update once
with the command below. See 0.0.6
for thumbnails that fill Finder's icons and the app's settings,
0.0.5 for XISF images and
0.0.3 for zoom and the FITS files
of X-ray missions.

Install with one command in Terminal:

curl -fsSL https://github.com/lmytime/uFits/releases/download/v0.0.7/install.sh | sh

It downloads the disk image below, checks its SHA-256, copies uFits to Applications and
turns on its Quick Look extensions. Then select a FITS or XISF file in Finder and press
Space.
To remove uFits, run the same command with sh -s -- --uninstall at the end.

Or by hand: open the disk image and drag uFits onto Applications. The app is not
notarized, so macOS blocks it at first: run
xattr -dr com.apple.quarantine /Applications/uFits.app, or open uFits and click
Open Anyway under System Settings › Privacy & Security. Then open uFits once to
register its Quick Look extensions.

Universal (Apple silicon and Intel), macOS 11 or later.
