Download Oxygen Not Included for macOS

Engineers who love sprawling logistics, biologists fascinated by closed ecosystems, and anyone who names their digital citizens before dooming them will feel right at home.

Duplicants — your colonists, each arriving with their own traits and quirks. One might learn planning quickly; another solves problems creatively. Keep them happy or watch productivity crumble into protests.

The Asteroid — the starting rock you pick shapes every resource hunt that follows. Expanding the base means suiting up and mining in dangerous ravines outside your cozy oxygen bubble.

Resources — everything gets consumed, and consuming everything creates waste. That waste can spark disease chains that sweep through the colony faster than you can mop up.

Survival Loop — a hardcore simulator dressed in strategy-game clothes. Lower happiness tanks task performance, a gasket deconstruction spawns the wrong element, and suddenly you're fighting cascading failures instead of building.

Some of the best quality-of-life touches hide just beneath the surface. Dragging a duplicant's portrait upward reveals a priority pane where you can fine-tune which tasks they tackle first — perfect for steering a gifted digger away from mopping duty while a cavern needs clearing. The scheduling tab, often ignored in the rush, lets you stagger downtime so the massage table never gets swamped by a dozen stressed-out colonists at once. And the materials overlay, toggled by a button that looks suspiciously like a layer cake, color-codes every gas and liquid pocket on the map so carbon dioxide buildups stop being invisible killers.

Quiet shortcuts worth stealing

• Press F9 to snapshot the entire asteroid — great for planning pipe spaghetti later without unpausing the chaos.
• Holding Shift while placing tiles draws a straight line; Shift + drag lets you lay out whole ladders and tunnels in one motion.
• The sweep tool marks loose debris for pickup, but assigning it to a storage bin’s filter is the real trick — duplicants stop hauling ore into the clean water reservoir by accident.
• Right-clicking the cycle sensor or timer sensor and choosing "Copy Settings" pastes the same rhythm onto every incubator or light in the room, no manual retyping needed.

Disable auto-assign so your best digger doesn’t mop

Open the options menu before unpausing and switch Auto-Prioritize New Duplicants to off — the game’s default job assignments rarely match the colony’s actual needs, and you will want to hand-pick who scrubs the outhouses. While you are in there, turn on Disable Disinfect for tiles above a certain germ threshold. This stops duplicants from wasting half a cycle scrubbing walls they will never lick, and you can always re-enable it if a slime lung outbreak actually lands. If your Mac’s fans are already spinning up, drop the Resolution Scale a notch — Klei optimized texture arrays and liquid rendering in recent builds, but big colonies still churn through memory, and the art style holds up beautifully even at 90%.

Who digs deepest into the asteroid

Logistics lovers who daydream about conveyor loops get the most mileage — the kind of player who designs a bathroom sieve that recirculates polluted water through a chlorine room just because the math works out. Engineers and systems thinkers gravitate toward the thermal dynamics and gas pressure rules that govern every cubic tile; watching a hydrogen bubble float upward because you placed a vent one cell too low is the sort of lesson that sticks forever. Creative problem-solvers who enjoy managing personalities thrive here too, because a duplicant with the Binge Eater stress response can empty the food stores faster than a harvest drought. Anyone chasing an oxygen not included mac download with the patience for failure loops — because the first three bases will collapse — will find the exact game they suspected the trailer was promising.

On the flip side, players who want a gentle city painter or a god game where nobody dies of suffocation should look elsewhere. The asteroid does not negotiate.

First-cycle survival blueprint

Day one is a race against carbon dioxide pooling at the lowest point of the base, so dig a pit beneath the printing pod before you build anything decorative. Drop an outhouse and wash basin first — duplicants who relieve themselves on the floor tank the colony’s morale within two cycles. Then plunk down a manual generator connected to a single small battery, because oxygen diffusers drain power and you need them puffing before the breathable air thins out. Resist the urge to take every duplicant the pod offers; a colony of four can coast on mealwood and algae for ages, while eight hungry mouths turn the fridge into a countdown timer.

Once the oxygen is flowing and the latrine is operational, open the Jobs menu and assign one researcher to the supercomputer. Those early techs unlock planter boxes and plumbing, which means you can wall off the toilet from the barracks before the decor penalty saps everyone’s mood. By cycle five, if you see a duplicant holding their breath in a corner, pause immediately, dig toward them, and check the gas overlay — it is almost always a CO₂ pocket you forgot about. If you grabbed the Oxygen Not Included torrent before reading guides, you get to experience the pure, unfiltered learning curve where those first five cycles teach you more than any walkthrough ever could; that is not a bug, it is the tutorial the asteroid writes for you each time you fail.

A hotfix landed on July 28, 2026, squashing a few strange bugs. Rescued duplicants no longer teleport to the bottom-left corner of the world, the Masterworks skill string correctly mentions Masterpiece artwork quality, and a gasket deconstruction issue that spawned the wrong element got patched. A liquid rendering glitch on older graphics cards is also fixed.
