v1.1.0

Cross-Platform Update Support

New

• macOS support — the updater now embeds and runs the .dmg installer on macOS: it mounts the image with hdiutil, copies the .app to /Applications via ditto, then unmounts.
• Linux support — the updater now embeds and runs the .deb package on Linux using pkexec dpkg -i and relaunches the app from /usr/bin/void-presence on completion.

Improved

• Platform-aware binary selection — extractInstaller now looks for the correct embedded asset prefix and extension per OS (Void.Presence.Setup.*.exe on Windows, Void.Presence.*.dmg on macOS, Void.Presence.*.deb on Linux).
• Cross-platform process tracking — isProcessAlive uses the Windows API on Windows and syscall.Kill(pid, 0) on Unix, keeping the goroutine-based install watcher working on all platforms.
• Cross-platform log path — log files are written to %LOCALAPPDATA%\voidupdates on Windows, ~/Library/Logs/voidupdates on macOS, and ~/.local/share/voidupdates on Linux.
• GitHub Actions matrix build — build-installer.yml and test.yml now build the updater for all three platforms in parallel, each embedding the matching platform artifact from void-presence.
