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.
SevenWins isn’t Apple-notarized yet, so macOS blocks the first open with “Apple could not verify…” — expected during the beta, not a virus. Open SevenWins from your Applications folder (not straight from the .dmg — that never works), let it get blocked, then go to System Settings → Privacy & Security, scroll to the bottom, click Open Anyway, confirm with Touch ID or your password, and click Open. You only do this once. (On macOS 12–14 you can instead right-click the app → Open → Open; Apple removed that shortcut in macOS 15.)
Rare — but if macOS says the app is damaged, or nothing happens at all when you open it, the download kept a stale “from the internet” tag. Open Terminal, paste this one line, press Return, then open SevenWins again:xattr -dr com.apple.quarantine /Applications/SevenWins.appIt only clears that tag on the app you just installed — nothing else on your Mac changes. This step disappears once we’re Apple-notarized.
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. If the only button you can see is “Don’t run”, you haven’t clicked More info yet — Run anyway only appears after that. This is expected during the beta.
On first launch, allow SevenWins to read the screen so it can show the overlay over MTG Arena.
