Penio v1.0.15 (Unsigned)
Install Instructions
macOS — The app is self-signed but not notarized by Apple. You will see two security warnings — this is expected. Here's how to get past them:
Step 1 — Opening the DMG
macOS will say the file "can't be opened because it is from an unidentified developer."
→ Open System Settings → Privacy & Security, scroll down, and click Open Anyway next to the Penio message.
Step 2 — Launching the app for the first time
macOS will warn again when you first open Penio from Applications.
→ Go to System Settings → Privacy & Security again and click Open Anyway.
These warnings only appear once on first install. Future updates will not ask again.
Windows — If SmartScreen appears, click More info → Run anyway.
Linux — .deb for Debian/Ubuntu, .rpm for Fedora/RHEL, .AppImage runs without install.
