Uncork Reviews and Details

Uncork is a free Mac app for Apple Silicon (M1 or later, macOS 14 or later) that runs Windows games from Steam and the Epic Games Store through a compatibility layer. It is notarized by Apple, so it opens like any other app. No account is needed.

What it does:

• One button sets up the engine, graphics libraries and Windows Steam. No Terminal, no Homebrew.
• Picks the graphics backend per game from its DirectX version (D3DMetal or DXMT for DX10–12, built-in OpenGL for DX9), and you can override it for one game.
• "Find out why": after a crash it reads the log and names the cause when it recognises it (missing .NET or DirectX, fonts, the Steam overlay, a controller seen twice), with a fix you can undo.
• Moves bottles from Whisky, which is no longer maintained: since Uncork 1.2 it copies a Whisky bottle with the installed games (APFS clone, the original is never changed). It takes about a minute and almost no extra disk space.
• macOS Game Mode for Windows games, controller mode for DualSense and Xbox pads, per-game Mac app shortcuts.

Optional Uncork Pro is €19 once, no end date, every 1.x version: the mouse read straight from the device at its own rate (measured 25 Sep 2026 with a 1000 Hz mouse: 843 movements a second versus 119 batches through macOS), Even frames for single-player games on ProMotion screens, an in-game panel with fps and frame pacing, Assetto Corsa in one click and Logitech wheel force feedback. 7-day Pro trial, nothing renews, 14-day refund with no reasons asked.

Limits: games with kernel-level anti-cheat (Valorant, Fortnite, Apex Legends, PUBG) do not run; Rosetta 2 is required. Tested games and measurements: https://uncork.win/en/games.html
