Backlight 0.9.1

Download: Backlight-0.9.1.zip, with Backlight.app inside: unzip, move it to Applications. A release is the build with the agent tools (Settings › Agents, off until you turn it on); the plain build is ./build.sh from the source.

It is self-signed, not an Apple Developer ID, so the first time macOS refuses to open it: open it once, then System Settings › Privacy & Security › Open Anyway.

Requires: macOS 27 on Apple silicon.

Updates. Backlight updates itself: Backlight menu › Check for Updates…, and once a day by itself unless Settings › General turns that off. Update and Restart downloads the zip, checks it against its SHA-256 and the app in it against this app's identifier, then replaces the old app (which goes to the Trash) and opens the new one. Nothing is installed without your say.

New since 0.9.0

• The icon file is a tenth of its size. 0.9.0's was 1.4 MB, a quarter of the app, because macOS's own tool stores every picture in it uncompressed. The large sizes now use a 256-colour palette (the glow looks the same) and there is no 1024 px one (macOS scales the 512 px). The app is 4.8 MB, not 6.1, and the download 2 MB, not 3.3.

Coming from BasicShell: quit BasicShell, then open Backlight; it brings your tabs, sign-ins and settings along (0.9.0's notes say what and how). BasicShell can't update itself to Backlight, since it has a different identity: download once, and Backlight updates itself from there.

After updating, quit and reopen Backlight if it did not restart itself, and start a new chat in your agent.
