Download

Pre-built installers are available on the Releases page — no Python installation required.

Platform	File	Notes
macOS	PyGRA-macos.dmg	Open the DMG, drag PyGRA to the Applications folder. On first launch macOS may block the app — see macOS security note below.
Linux	PyGRA-linux.tar.gz	Extract and run ./PyGRA/PyGRA directly.
Windows	PyGRA.exe	Run directly. Windows may show a SmartScreen warning — click More info → Run anyway.

macOS security note

Since PyGRA is not signed with an Apple Developer certificate, macOS may block it on first launch with the message “Apple cannot verify that PyGRA does not contain malware”. To open it:

1. Open System Settings → Privacy & Security

2. Scroll down to the Security section

3. Click “Open Anyway” next to the PyGRA message

4. Confirm by clicking “Open” in the dialog that appears

This is a one-time step — subsequent launches will open normally.

Windows security note

Windows SmartScreen may show a warning when running PyGRA.exe for the first time, since the app is not signed with a Microsoft certificate:

1. Click “More info”

2. Click “Run anyway”

This is a one-time step.
