Lorium v1.0.0-alpha

v1.0.0-alpha

Installers are attached to this release. ### macOS — “Apple could not verify…” This build is not notarized, so macOS blocks it on first launch. The app is safe, but it is not signed with an Apple Developer ID. To open it: - Remove the quarantine attribute, then open the app normally: ```bash xattr -dr com.apple.quarantine "/Applications/Lorium.app" ``` - Or launch it once (macOS will block it), then open System Settings → Privacy & Security and click **Open Anyway** next to the Lorium message. (Right-click → **Open** no longer bypasses Gatekeeper on macOS 15+.)
