The native MTG Arena assistant — live pick ratings, board reads, and chess-style game review, right over your game. Free through the beta.
Open the downloaded .dmg and drag SevenWins into your Applications folder.
macOS may say the app is from an unidentified developer. Right-click (or Control-click) the app → Open, then confirm. Or go to System Settings → Privacy & Security, scroll down, and click Open Anyway.
On first launch SevenWins asks for Screen Recording permission — it needs this to draw the overlay over your game. Approve it in System Settings → Privacy & Security → Screen Recording, then relaunch.
Open SevenWins-win.exe once it finishes downloading.
Windows may show “Windows protected your PC” because the app isn’t code-signed yet. Click More info → Run anyway. This is expected during the beta.
On first launch, allow SevenWins to read the screen so it can show the overlay over MTG Arena.
