Oxygen Not Included on your Mac — 744825

The latest update, version 744825, is a hotfix that clears up several nagging issues. Duplicants rescued and resuscitated no longer teleport to the bottom left of the world, a navgrid memory leak is plugged, deconstructing buildings with gaskets now spawns the correct element, and a liquid rendering bug on older graphics cards is fixed. If you hit any of those snags, this release is worth grabbing.

For planners who enjoy watching mistakes snowball

• Players who like planning ahead and juggling many systems at once. This game demands constant attention to bladder fullness, stress, and workload.
• People who enjoy watching their own mistakes snowball. Waste can trigger a chain of diseases, so small oversights become big problems.
• Fans of individual quirks. Most colonists have unique character traits that shape how they behave and what they need.

Not for relaxed players or quick wins

If you prefer a relaxed pace or want to win quickly, this may frustrate you. Managing a base and several duplicants is very difficult, and the challenge only grows as they require relaxation machines and produce more waste. You start on an asteroid you choose at the beginning, and from there it is a constant fight to keep everyone alive. That is the draw for some, and a wall for others.

Steep learning curve expects lost colonies

Do I need to know anything about colony sims to start? Not really. The game teaches its own logic as you go, though the learning curve is steep. Expect to lose a few colonies while you figure out how oxygen, water, and waste connect. Most players restart several times before a base stabilises, and that is part of the experience.

Can I play this without an internet connection after I have the files? Yes. Once the game is on your Mac, you do not need to be online to play. It is a single-player simulation with no live services or always-online checks.

Does the game support controllers or is it keyboard and mouse only? Keyboard and mouse is the standard way to play. The interface is built for point-and-click management, and I have not seen controller support mentioned in any recent patch notes. A mouse with a scroll wheel helps when you are panning around a large asteroid.

Is there any paid content or dlc added later? I am only covering version 744825 as it is. If you want expansions, that is a separate search.

Building blueprints auto-avoid overlapping structures

When you drag a building blueprint over a large area, the game automatically adjusts the placement to avoid overlapping existing structures. This saves time when you are laying out rows of beds or storage bins.

Duplicants develop skills while performing tasks, and the game tracks which colonists learn planning easily, which are good at digging because tool use is familiar to them, and which excel at creative problem solving. That information is visible in their character panel, and it helps you assign jobs more efficiently.

Pausing the game does not stop the info overlays. You can toggle oxygen, temperature, or light overlays while paused to plan your next move without pressure.

The priority system lets you set task urgency per duplicant and per errand. If someone is about to starve because they keep ignoring the cooking station, you can bump that task to high priority without changing everyone else's routine.

Turn on the oxygen overlay before your first dig

Before you assign your first dig order, open the game's settings and turn on the overlay that shows oxygen levels. You will want to see where breathable air is thinning before duplicants start gasping. Keep it visible while you learn the basics.

Adjust the alert thresholds. The default settings may not warn you early enough about low food or high stress. Move the sliders so you get a notification when food drops below a comfortable surplus, not when it is already gone.

Under the graphics options, check that the liquid rendering fix from version 744825 works correctly on your Mac. If you have an older graphics card and notice strange water or polluted water visuals, toggle the setting once and back again to force a refresh. Some players find that helps after the hotfix.

Finally, take a moment to rename your first few duplicants. It makes tracking their traits and skills easier when you are managing a dozen colonists and each one has a name you remember.
