Mac版のSteamでWindows版ゲームを動かす「NotProton」の存在を知る。もちろんCrossoverは(実質)必須だけど、使い分ける必要はなくなって簡単に。確かにこれは便利だ。 NotProtonNot/NotProton

If you have a issue with running the game submit it in the project's GitHub repository in the issue section, that way it can be tracked by everyone and I can respond directly, do not ask in YouTube comments.

@BeeperId @raymondchins hell yeah, the original NotProtonNot/NotProton

NotProton is fantastic - it allows Mac users to run Windows games from native MacOS Steam, without futzing with Crossover bottles. It uses Crossover internally but makes it totally transparent - just like Proton on Linux. NotProtonNot/NotProton #macgaming

NotProton GitHub Explained: Steam Play Architecture and macOS Limits notproton by notprotonnot: notprotonnot/notproton NotProton is a system-level macOS integration layer that connects the native Steam client to CrossOver for Windows game execution. This overview explains why Apple Silicon, 32-bit deprecation, and Metal/Vulkan differences create the compatibility gap; how a custom dylib, ported lsteamclient, steam-shim, and ntdll patch connect Steam IPC to a CrossOver prefix; and how Rosetta 2, FEX, and APFS cloning shape runtime and storage behavior. It also covers Gatekeeper friction, controller-routing issues, the CrossOver-only dependency, NTFS limitations, and the hard boundary: VAC-protected online matchmaking remains unsupported and runs in insecure mode.

The tradeoff is equally important. Apple-formatted storage, compatible CrossOver builds, macOS security workarounds, and single-player expectations matter; VAC-protected online multiplayer remains outside the supported path. #NotProton #macOSGaming #SteamPlay [de-DE] NotProton GitHub erklärt: Steam Play-Architektur und macOS-Grenzen NotProton von NotProtonnot: notprotonnot/notproton NotProton ist eine macOS-Systemintegrationsschicht, die den nativen Steam-Client mit der Spielausführung über CrossOver für Windows verbindet. Diese Übersicht erklärt, warum Apple Silicon, die Abschaffung der 32-Bit-Architektur und die Unterschiede zwischen Metal und Vulkan die Kompatibilitätslücke verursachen; wie eine benutzerdefinierte dynamische Bibliothek (dylib), ein portierter lsteamclient, steam-shim und ein ntdll-Patch die Steam-IPC mit einem CrossOver-Präfix verbinden; und wie Rosetta 2, FEX und APFS-Klonen das Laufzeit- und Speicherverhalten beeinflussen.

Launch all games (windows AND mac games) trough native steam client! Proton-ish: Steam Play for Mac using Highball's free Wine, no CrossOver license needed (early beta) Hey r/macgaming, I've been building Proton-ish, a small Mac app that lets you play Windows Steam games straight from your normal macOS Steam client, without paying for CrossOver: MagnusPladsen/Proton-ish How it works: Proton-ish turns on Steam Play in the Mac Steam client and plugs in Highball as the Wine runtime. Highball is a free, open source app for running Windows games on Apple Silicon, and its Wine 11 engine is really good. Install Highball, click Set Up in Proton-ish, and Steam gets a "Highball Wine 11" compatibility tool. Why I like it: - Works like the SteamOS/Linux experience: Windows games are launched through native Steam and automatically run through the compatibility layer. - It feels native. No bottles, no separate launcher, no Windows Steam running inside Wine. You open your regular Mac Steam, pick the compatibility tool for a game and press Play. - Your library, achievements, overlay and cloud saves all go through the real Steam client. - Way less setup and config than the usual Wine routes. After the one-time setup there's basically nothing to tweak. - It's free. If you already own CrossOver, that still works too. Where it's at: very early. This is the first pre-release, and the few games I've tested on my M-series Mac run really well so far. Expect rough edges. Anti-cheat games won't work (same as on Linux/Steam Deck). Graphics use DXMT for now; choosing D3DMetal/DXVK per game is next. Coming up: Highball has a community compatibility database, highball-db. I want Proton-ish to pull per-game fixes from it, so games that already work in Highball work here without manual tweaking. I'd love testers. Grab the pre-release here: github.com/MagnusPladsen/Proton-ish/releases. Tell me what works and what breaks (bug reports on GitHub). Credits: Proton-ish is a fork of NotProton, which did all the hard Steam integration work. That's why CrossOver still works in Proton-ish. Huge thanks to the NotProton dev, and to the Highball dev for the engine and the database. Proton-ish isn't affiliated with either project, so please send Proton-ish bugs to me and not to them. And if you can afford CrossOver, it's worth buying: CodeWeavers basically funds Wine on the Mac.

For Mac users: There's a new tool called NotProton which allows you to use Crossover directly via the Mac client of Steam It does require blocking steam updates because otherwise it might break. NotProtonNot/NotProton t.co

I need to purchase CrossOver to test this out, but this is *extremely* cool! Making it so you can just press Play on a Windows game *using* the macOS version of Steam, *without* needing the Windows version? Thank you!

Play any game on mac through native steam client Since notproton is here now you can play any game on native steam client directly it works like proton for linux and steamdeck, under the hood its using crossover you can check this video to see how it works and how to setup its really good you need active subscription of crossover it's infinite trial method will not work cracks exists look on fmhy i recommend appstorrent. Now you'll know about lua tools and stuff its available on mac too a cool project called macsteam you can watch this video to understand how it works and how to setup it does usual lua stuff for native steam client but was only useful for native mac game now since notproton is here you can use this together and can play anything on steam just install notproton first then macsteam, on first launch game may take sometime its normal if dosent work repair steam and install notproton again then install macsteam.
