Mac Source Ports

FreeSpace 2 was the sequel to Descent: FreeSpace - The Great War. The first game was unrelated to the Descent series and only used the name to avoid conflict with a commercial software utility, so the sequel dropped it.

Although not a commercial success, it gained a cult following, especially in the wake of the 2002 release of the source code which gave rise to the FreeSpace 2 Source Code Project, one of the oldest continously maintained source ports in existence. In 2022 they added Mac support and in 2024 they added Apple Silicon support.

NOTE: The links below are to the Mac builds of the game, but there also exists a project called Knossos.NET which consists of a utility which will handle the installation and configuration for you, including installing the data files from GOG installers. For the quickest route to getting the game check out the Knossos.NET entry on our Utilities page.

The story goes that Activision commissioned an expansion pack for Return to Castle Wolfenstein, which like the base game would offer both a single and multiplayer campaign, each assigned to different developers. For whatever reason, the single player campaign did not meet expectations while the multiplayer component was coming along nicely so the decision was made to cancel the expansion pack but release the multiplayer portion standalone for free as Wolfenstein: Enemy Territory.

Although we have numerous options today, in 2003 this was an almost unheard of phenomenon: a free game with no strings attached and whose tech for mods and map making were already in use by the community. In 2010, the source code for the full game was released and the ET: Legacy project has been actively maintaining for years now, with an enthusiastic player base continuing to populate servers two decades later.

NOTE: due to the nature of compiled mods, not all servers may be playable for non-Windows players. Look for servers running the "Legacy" mod for the best chance of connection success.

So this is interesting, I just stumbled on this randomly a few weeks back right after it was released, although it was apparently in the works for twenty years.

Quetoo is an open source project that's a combination of id Tech engines and technologies, incorporating every graphics technique the source port communities are known for, and recreating some of the classic maps of the Quake series without actually using any of its data.

The result is a purely community focused freeware arena shooter that can even be edited with modern tools like Trenchboom.
Definitely one to keep an eye on.

Are you tired of waiting five years for a new game, only to have it cost even more than last time and then the developers get laid off by a heartless corporation? Well then do I have a deal for you.

BRAZILIAN DRUG DEALER BEFORE 4 is the sequel to BRAZILIAN DRUG DEALER 3, and judging from the title your business from the first game isn't finished, and now you have to save someone from a soccer star. Or a clown. I'm not sure.

I've mentioned it before but back in the day, you had game developers which could take a handful of people, make a game on a small budget, turn a profit, and then crank out am upgraded sequel in a year. Well, Joeveno and NoQuarter are doing that again. Literally - the release dates of 3 and 4 are almost one year apart to the day. And BRAZILIAN DRUG DEALER BEFORE 4 features updates like double jumping, dash moves, and a new UI.

I love AAA gaming like everyone else but I miss the good old days when gaming was more fast and furious, so I'm a big fan of these guys now, and not just because I got to hang out with them at QuakeCon 2026. As a bonus, this is not only the newest game on Mac Source Ports (as of this writing) but it's the first time we've been able to add a Mac build of a game on release date.

I'm pretty sure that of all the games on this site, this is the first one I've ever built that I originally played on the iPod. Zuma is essentially a match-3 puzzle game, with the twist being that the tiles are balls rolling down an etched path, and you play as a stationary frog idol thing and shoot matching balls from your mouth, with the goal to be clearing the chain before it can reach tne end of the path.

It has great music and sound design, colorful graphics, addictive gameplay, and works great for both quick diversions as well as extended gameplay sessions. I almost wish you could still use an iPod wheel as a controller.

Zuma was later re-released in an enhanced version dubbed Zuma Deluxe, which is the version you can still get off of Steam to this day, and the version that Zuma Portable uses.

From a time when it seemed LucasArts could do no wrong, Star Wars: TIE Fighter is a space simulation game that flips the script on the original Star Wars trilogy, putting you in the role of a TIE Fighter pilot for the Galactic Empire. You must complete a series of missions that involve defending the Empire's interests, hunting down Rebel Alliance targets, and engaging in tense dogfights with enemy ships. The game features a deep and engaging storyline, a variety of ship upgrades and weapons, and detailed graphics and sound effects that bring the Star Wars universe to life. With its challenging gameplay, complex strategy, and innovative features, Star Wars: TIE Fighter is another true classic of the space simulation genre.

Plants vs. Zombies is an example of casual game perfection, from developer PopCap Games at their peak, pre-acquisition. Effectively a tower defense game without being a tower defense game, it has a difficulty curve so incredibly well done that at some point you're pulling off elaborate strategies without ever feeling like you're not ready for it. With an addicting amount of depth, additional mini-games once you finish the campaign, and no microtransactions or mismatched mechanics, it's a game that absolutely holds up.

It's also a game where I had no idea there was a modding community, let alone a nearly perfect reverse engineered source port nearly five years in the making. I honestly thought for a minute it was some sort of trick but no, PvZ Portable is a true reverse engineered port.

NOTE: While PvZ-Portable definitely works with Plants vs. Zombies: Game of the Year Edition, I'm not clear if it works with the regular (non-GOTY) edition. As of this writing the GOTY edition is the only version on Steam. As far as I can tell it does not work with the recent Plants vs. Zombies: Replanted edition.

You can't *not* have DOOM on a site like this. With its classic and low system requirements, DOOM famously runs on anything with a screen and a processor, so naturally it (still) runs on the Mac. The most active source port is GZDoom, which is ahead of the curve on having a Universal 2 app with M1 Mac support so we're just linking to it here. Be sure to check out their website for more info.

We've also linked to ZDoom, an older but discontinued predecessor to GZDoom, for those of you who want to run DOOM on an older PowerPC Mac.

The retail sequel to DOOM eschews episodes for one long campaign of levels. Adding new weapons and monsters, DOOM II delivers on its promise of more DOOM.

Final DOOM was a retail product which contained two 32-level campaigns, TNT: Evilution and The Plutonia Experiment. It used the same weapon and feature set as DOOM II and the episodes were contracted out from the DOOM level editing community.
