The Oregon Trail — the computer-lab one Runs here
1990 · MECC · System 7 · Mini vMac (Mac II) · 640×480 at 8-bit colour
Guide updated September 2026
Almost everyone who sat in front of a school Macintosh in the 1990s played this. Not the Apple II green-screen original, and not the phone remake — this one, with the drawn title screen, the general store at Independence, and the river you were never sure whether to ford.
It is MECC's Macintosh release, and it runs here on an emulated Mac. You pick a profession, buy supplies with money you will immediately regret spending, and set out in April with five people in a wagon.
Boots straight to the title screen on an emulated Macintosh II. Click Travel the Trail, choose a profession — banker is easy, farmer is hard and scores triple — and buy supplies before you leave.

MECC was a Minnesota state agency, then a company, then sold to SoftKey, then to The Learning Company, then to Mattel, and the trail eventually reached Houghton Mifflin Harcourt. The Macintosh release has not been sold in any form for more than twenty-five years, and no current product contains it — the 2021 mobile and Switch remakes are new software. Full reasoning is in notices/oregon-trail.md, and the takedown promise applies without argument.

This is the Macintosh build, so the art is the detailed pen-and-ink work the Mac version is known for rather than the blocky Apple II graphics. It uses a small palette — the title screen is essentially two-tone on parchment — which is what the machines of the day could manage and what the artists drew for.
Everything is mouse-driven. The one thing worth knowing before you start is that the game does not warn you when you are making the decision that kills you; it just quietly notes it and lets you find out three weeks later.
How not to die immediately
Leave in April or May. Leave in March and you hit snow in the mountains. Leave in July and you hit snow in the mountains.
Buy more oxen than you think you need. A dead ox is a stopped wagon, and a stopped wagon in October is the end of the run. Two spare yoke is not excessive.
Do not shoot more than you can carry. Hunting is the most fun part of the game and the easiest way to waste a day: you can only haul a few hundred pounds back to the wagon, and everything else rots where it fell.
Slow the pace and raise the rations when people get sick. Grueling pace plus bare-bones rations is how a party of five becomes a party of one, and the game will let you do it all the way to the end.
Ford only shallow water. Under two and a half feet, ford it. Deeper than that, take the ferry or hire the guide and pay the money. Everyone learns this once, expensively.
Why this version is the one people remember
The Oregon Trail started in 1971 as a text program written by three student teachers in Minnesota, typed into a mainframe and played over a teletype. MECC — the Minnesota Educational Computing Consortium — spent the next two decades rebuilding it for each new machine that arrived in schools.
The Apple II version is the one with the historical claim; it is what put the game in classrooms in the first place. But the Macintosh release is the one most people picture, because it is what the school computer labs of the 1990s actually had, and because it is the first version that looked drawn rather than plotted.
It is also a genuinely unusual piece of educational software: it teaches by killing you. There is no quiz and no score screen explaining what you should have learned. There is a long journey, a set of resources, and a river.
Questions people ask
Is this the version I played at school?
If you were on a Macintosh, almost certainly. This is MECC's Macintosh release — the drawn artwork, the mouse-driven store, the ford-or-ferry decision. The Apple II original looks quite different.
Do I need to install anything?
No. The emulated Mac and the disk both load in the page. There is nothing to download and no plugin.
Why do I keep dying of dysentery?
Bad water and a hard pace. Slow down, raise the rations, and rest when someone falls ill. The game is happy to let you push a sick party until nobody is left.
Should I ford the river or take the ferry?
Ford it if the depth is under about two and a half feet. Deeper than that and you are gambling your oxen, your supplies and usually a person against the cost of the ferry.
Which profession should I pick?
Banker starts rich and scores single points. Carpenter is the middle. Farmer starts poor, scores triple, and is the one to pick once you have finished the trail at least once.
Will my game be saved if I close the tab?
Saves live inside the emulated Mac, in your own browser. They survive closing the tab but not clearing site data, and they do not follow you to another device.
Can I play it on a phone?
It will load, but the game expects a mouse and a keyboard for hunting, so a desktop or laptop is much better.
