So, you’ve decided to download an older version of Mac OS X. There are many reasons that could point you to this radical decision. To begin with, some of your apps may not be working properly (or simply crash) on newer operating systems. Also, you may have noticed your Mac’s performance went down right after the last update. Finally, if you want to run a parallel copy of Mac OS X on a virtual machine, you too will need a working installation file of an older Mac OS X. Further down we’ll explain where to get one and what problems you may face down the road.

A list of all Mac OS X versions

Explore the world of Mac. Check out MacBook Pro, MacBook Air, iMac, Mac mini, and more. Visit the Apple site to learn, buy, and get support. When using your Mac, maintaining a small amount of free drive space is required to keep your system running optimally. While nothing stops you from adding files to your drive until it can hold no. DaisyDisk, GrandPerspective, and Disk Inventory X are probably your best bets out of the 10 options considered. 'Helps find and delete files taking up HDD space' is the primary reason people pick DaisyDisk over the competition. This page is powered by a knowledgeable community that helps you make an informed decision.

We’ll be repeatedly referring to these Apple OS versions below, so it’s good to know the basic macOS timeline.

1. Space Nomad is a survival building game where you establish and protect your home: a spaceship. Expand your ship and avoid destruction from the hazards of such a lifestyle. Move around both inside and outside the ship. Build from inside. Divert incoming asteroids from outside.
2. If you've been using a previous file system, it will be automatically updated when you upgrade to Mac OS Mojave. Files On-Demand settings are unique to each device, so make sure you turn it on for each device where you want to use it. To learn how an admin can turn on Files On-Demand, see Configure Files On-Demand for Mac (IT administrators).

STEP 1. Prepare your Mac for installation

Given your Mac isn’t new and is filled with data, you will probably need enough free space on your Mac. This includes not just space for the OS itself but also space for other applications and your user data. One more argument is that the free space on your disk translates into virtual memory so your apps have “fuel” to operate on. The chart below tells you how much free space is needed.

Note, that it is recommended that you install OS on a clean drive. Next, you will need enough disk space available, for example, to create Recovery Partition. Here are some ideas to free up space on your drive:

• Uninstall large unused apps
• Empty Trash Bin and Downloads
• Locate the biggest files on your computer:

Go to Finder > All My Files > Arrange by size
Then you can move your space hoggers onto an external drive or a cloud storage.
If you aren’t comfortable with cleaning the Mac manually, there are some nice automatic “room cleaners”. Our favorite is CleanMyMac as it’s most simple to use of all. It deletes system junk, old broken apps, and the rest of hidden junk on your drive.

Download CleanMyMac for OS 10.4 - 10.8 (free version)

Download CleanMyMac for OS 10.9 (free version)

Download CleanMyMac for OS 10.10 - 10.14 (free version)

STEP 2. Get a copy of Mac OS X download

Normally, it is assumed that updating OS is a one-way road. That’s why going back to a past Apple OS version is problematic. The main challenge is to download the OS installation file itself, because your Mac may already be running a newer version. If you succeed in downloading the OS installation, your next step is to create a bootable USB or DVD and then reinstall the OS on your computer.

How to download older Mac OS X versions via the App Store

If you once had purchased an old version of Mac OS X from the App Store, open it and go to the Purchased tab. There you’ll find all the installers you can download. However, it doesn’t always work that way. The purchased section lists only those operating systems that you had downloaded in the past. But here is the path to check it:

1. Click the App Store icon.
2. Click Purchases in the top menu.
3. Scroll down to find the preferred OS X version.
4. Click Download.

This method allows you to download Mavericks and Yosemite by logging with your Apple ID — only if you previously downloaded them from the Mac App Store.

Without App Store: Download Mac OS version as Apple Developer

Space Nomad Mac Os X

If you are signed with an Apple Developer account, you can get access to products that are no longer listed on the App Store. If you desperately need a lower OS X version build, consider creating a new Developer account among other options. The membership cost is $99/year and provides a bunch of perks unavailable to ordinary users.

Nevertheless, keep in mind that if you visit developer.apple.com/downloads, you can only find 10.3-10.6 OS X operating systems there. Newer versions are not available because starting Mac OS X Snow Leopard 10.7, the App Store has become the only source of updating Apple OS versions.

Purchase an older version of Mac operating system

You can purchase a boxed or email version of past Mac OS X directly from Apple. Both will cost you around $20. For the reason of being rather antiquated, Snow Leopard and earlier Apple versions can only be installed from DVD.

Buy a boxed edition of Snow Leopard 10.6
Get an email copy of Lion 10.7
Get an email copy of Mountain Lion 10.8

The email edition comes with a special download code you can use for the Mac App Store. Note, that to install the Lion or Mountain Lion, your Mac needs to be running Snow Leopard so you can install the newer OS on top of it.

How to get macOS El Capitan download

If you are wondering if you can run El Capitan on an older Mac, rejoice as it’s possible too. But before your Mac can run El Capitan it has to be updated to OS X 10.6.8. So, here are main steps you should take:

1. Install Snow Leopard from install DVD.
2. Update to 10.6.8 using Software Update.
3. Download El Capitan here.

“I can’t download an old version of Mac OS X”

Space Nomad Mac Os Update

If you have a newer Mac, there is no physical option to install Mac OS versions older than your current Mac model. For instance, if your MacBook was released in 2014, don’t expect it to run any OS released prior of that time, because older Apple OS versions simply do not include hardware drivers for your Mac.

But as it often happens, workarounds are possible. There is still a chance to download the installation file if you have an access to a Mac (or virtual machine) running that operating system. For example, to get an installer for Lion, you may ask a friend who has Lion-operated Mac or, once again, set up a virtual machine running Lion. Then you will need to prepare an external drive to download the installation file using OS X Utilities.

After you’ve completed the download, the installer should launch automatically, but you can click Cancel and copy the file you need. Below is the detailed instruction how to do it.

STEP 3. Install older OS X onto an external drive

The following method allows you to download Mac OS X Lion, Mountain Lion, and Mavericks.

1. Start your Mac holding down Command + R.
2. Prepare a clean external drive (at least 10 GB of storage).
3. Within OS X Utilities, choose Reinstall OS X.
4. Select external drive as a source.
5. Enter your Apple ID.

Now the OS should start downloading automatically onto the external drive. After the download is complete, your Mac will prompt you to do a restart, but at this point, you should completely shut it down. Now that the installation file is “captured” onto your external drive, you can reinstall the OS, this time running the file on your Mac.

1. Boot your Mac from your standard drive.
2. Connect the external drive.
3. Go to external drive > OS X Install Data.

Locate InstallESD.dmg disk image file — this is the file you need to reinstall Lion OS X. The same steps are valid for Mountain Lion and Mavericks.

How to downgrade a Mac running later macOS versions

If your Mac runs macOS Sierra 10.12 or macOS High Sierra 10.13, it is possible to revert it to the previous system if you are not satisfied with the experience. You can do it either with Time Machine or by creating a bootable USB or external drive.

Before you do it, the best advice is to back your Mac up so your most important files stay intact. In addition to that, it makes sense to clean up your Mac from old system junk files and application leftovers. The easiest way to do it is to run CleanMyMac X on your machine (download it for free here).

Visit your local Apple Store to download older OS X version

If none of the options to get older OS X worked, pay a visit to nearest local Apple Store. They should have image installations going back to OS Leopard and earlier. You can also ask their assistance to create a bootable USB drive with the installation file. So here you are. We hope this article has helped you to download an old version of Mac OS X. Below are a few more links you may find interesting.

Go To

In science fiction, when a space-faring race has no planet/asteroid etc to call home, and lives solely in space craft, they may be space nomads. Note that to be a true example of this trope the people in question have to actually move around once in a while (ie: be nomadic). If they're just living on a space station that is, well, stationary, then it's not a true example of this trope. The craft where these people live may consist of a scattered vessels wandering around on their own, a large and cohesive fleet, and/or huge Planet Spaceships which may in turn cause moments of That's No Moon! for characters in the story.

In real life, there are whole groups of 'Sea Gypsies' such as the Bajau people, and so this trope can fit well if Space Is an Ocean. The Space Nomads may be all that's left of the Precursors, in which case it's likely they suffered some sort of Götterdämmerung but obviously weren't fully wiped out. Space Nomads commonly appear in Space Operas.

The Space Nomads' potential reasons for wandering are many. Some are nomads for purely cultural reasons, while others may be traveling traders and merchants. Another variant is to have them as pirates, raiders and warriors who wander nomadically in search of targets; relatedly, it's common for Planet Looters to be this — once you've stripped a planet bare of resources, there's not much to do beyond looking a new one. Some may be running away from something, or trying to reach their homeland or even a new home, so they need not intend to be nomadic forever, but are still a whole group of people on a very long journey.

Subtrope of Space People.

Examples

• Wonder Woman:
  • Wonder Woman (1942): The 'Gremlins' choose to take up a spacefaring nomadic lifestyle after their successful Slave Revolt against the Ytirflirks. This is partially because the Ytirflirks devastated their home planet in the initial invasion and partially because in stealing the Ytirflirk mothership they provided themselves with a large enough ship to act as a wandering base for their people.
  • Wonder Woman (2006): The Citizenry used to be a collective of peaceful space wanderers, whose tradition of abducting/taking a child with them when they encountered new sentient species backfired when they took an Amazon who grew up resentful and forcibly took over and turned them into a planet killing genocidal group.

• Abraxas: King Ghidorah is revealed to be a Space Nomad of the Planet Killer variety — it's been moving from world to world, conquering each one and covering its surface in neverending tempests before moving on. Then it got stuck on conquering Earth.

• Titan A.E.: After the Earth is destroyed, most humans become wanderers moving around the galaxy.

• Independence Day: The aliens are like sentient space locusts, moving from world to world and stripping each bare of resources before moving on. It's however revealed in Independence Day: Resurgence that the aliens do in fact have a home planet, whih is actually where the distress signal is broadcast to to summon the Alien Queen and more forces.
• Wing Commander: The Pilgrims are a group of these, notable for their ability to navigate without the help of computers. They suffer from prejudice and persecution by most of the society, and previously went to war with the human government. It turns out Blair's mother was one. He keeps it quiet due to prejudice, but his abilities definitely come in handy during the film.

• All Tomorrows:
  • The Qu, who wander between galaxies in vast migrations on a quest to reshape the universe. This is what brought them to the worlds of men, and why they later left.
  • The Spaceborn, descended from those few humans who escaped the Qu invasion by creating hollow, moon-sized Generation Ships and adapting themselves for a life in zero gravity. They spent forty million years hiding in deep space, and after the Qu left they had become too specialized to re-adapt to planetary life.
• Citizen of the Galaxy: The Free Traders are a Proud Merchant Race who spend their entire lives hopping between planets, buying and selling.
• The Citizen Series: The Riders are a nomadic hunter-gatherer culture that travel from world to world on mysterious 'beasts' that can travel through the Continuum unaided.
• The Culture: Many people in the Culture live their lives on space craft which travel around, and consider planetary life to be a weird concept.
• In A Deepness in the Sky, the Qeng Ho traders are a loose collective of interstellar traders that travel via slower-than-light Ram Scoop-powered Sleeper Starships. The Qeng Ho hold that if they start to use the local time system (days/months/years) instead of their UNIX-time based system (seconds/kiloseconds/megaseconds, etc), they've been in the system for too long.
• Great Ship: The eponymous ship is a Jupiter-sized starship housing billions of transhuman beings that paid for their way onto the Starship Luxurious; either for only a short duration, a circuit around the Milky Way, or, for a much larger price, permanent residence. While the majority of the residents have planetary holdings, one race lost control of their own system and have a large community on the Great Ship. The Remoras, a Human Subspecies residing on the ship's outer hull, rarely enter the ship proper and spend their entire lives on the hull or in the space immediately around it.
• In Invasion: Earth, both alien races turn out to be this. They are The Remnant of two once-powerful interstellar civilizations, who were at war with one another. Presumably, the two civilizations destroyed each other, and the survivors banded together and now travel through space in what's left of their fleets, looking for more primitive races to scam for resources.
• Star Wars:
  • New Jedi Order: The Yuuzhan Vong were like this for much of their history. After their home galaxy was completely devastated during a massive war, they loaded their entire population onto massive organic worldships and left to find a new one. After being in transit for millennia, they finally arrive at the Galaxy Far Far Away... and, being the Yuuzhan Vong, promptly try to take over.
  • The Vagaari from Survivor's Quest and Outbound Flight are an interesting example of this, since the Unknown Regions sourcebook establishes that they do have a home world, their nomadic lifestyle is purely by choice. This aspect of their society makes it difficult for Thrawn to decisively defeat them, as the Vagaari fleet can simply disperse and regroup elsewhere. They live as wandering raiders, pirates and slavers, and rule over a sizable portion of the Unknown Regions where they roam unopposed.

• Firefly: Zoe (at least according to supplemental materials) is the daughter of two tramp freighter crewmembers and spent most of her childhood in space. Mal also counts, after a fashion: He grew up on the surface of a colony world, but after losing his home and family during the Unification War his only home is aboard the Serenity. Lastly, the Reavers are somewhere between an Always Chaotic Evil version of this trope and Space Cossacks, as seen in the Big Damn Movie: They have one region of space that they call home, but travel all over the 'verse looking for somewhere to Rape, Pillage, and Burn.
• Stargate Atlantis: The Travelers. They refuse to settle down due to the ever-present danger of the Wraith, who destroy all advanced cultures. In their first appearance, they kidnap Sheppard in order to use him to reactivate an AncientAurora-class battleship. Not to use a warship but to keep their increasing population on the huge ship.
• Star Trek: The Voth and the Varro. The USS Voyager spends most of its time traveling through the Delta Quadrant with no fixed base, as its primary mission is to find a way back to the Alpha and the Federation's worlds.

• The Space Gypsy Adventures: The space gypsies. Though recent persecution from the Federal Alliance has led to many of them in prison camps or hiding among planetary populations. Main characters Gemma and Damien tend to spend much of their time at the Drakester spaceport on Zenophon, seeing how it's outside the Alliance's jurisdiction.

• Eclipse Phase: The Scum are nomadic hedonists who fled from Earth during the Fall and never left their ships.
• Warhammer 40,000 has numerous examples.
  • Craftworld Eldar became this after the core worlds of their empire were destroyed by a huge cataclysm (the hedonism of the Eldar gave birth to a new Chaos God called Slaanesh who likes to eat Eldar souls), and now roam the Milky Way in immense Craftworlds, Generation Ships the size of small worlds. Staying put is not an option for them — they have too many enemies and not enough numbers or resources to work with — and so they travel and hide their locations.
  • The Tau-allied Demiurg, who are expies of the Bentusi. They're not even thought to have a homeworld, and the vast majority of their species lives on gigantic spaceships, seeking out asteroids to mine. That said, they do colonize worlds on occasion, if the mining is particularly good.
  • The Nicassar, another Tau subject species, are this as well, by virtue of being insatiable explorers and obsessed with traveling.
  • Orks only stay on a planet long enough to crush all opposition, steal the weapons, enslave the remaining population, and build themselves new spaceships so they can repeat the process.
  • The Diasporex, once of the civilizations encountered by the early Imperium during the Great Crusade, consisted of humans and aliens who led semi-nomadic lifestyles aboard fleets of starships. Unlike other Space Nomads, however, they were limited to a specific area of space due to their dependence on a number of space stations for refueling. This spelled their doom when the Imperium, incensed at the humans' refusal to turn on their alien allies, attacked the stations, forcing the Diasporex into a fight they couldn't win and wiping them all out.

• Endless Space:
  • The Pilgrims have taken up a nomadic lifestyle to escape the UnitedEmpire's oppressive regime. Thanks to their friendship with the advanced alien Sophons, and their understanding of Endless technology, they've been able to travel vast distances with ease and transport entire planetary populations. Both their religious and scientific goal as nomads is to find the lost homeworld of the Endless, Tor.
  • The Vaulters in Endless Space IIonly narrowly escaped the doomed world Auriga aboard a Generation Ship which was crippled for millennia until a Dust-filled asteroid belt revived the ship and saved them. They start with the 'Involuntary Nomads' trait, and a thriving world they can permanently settle is their faction's holy grail.
• Homeworld:
  • The Bentusi and the Vaygr, as well as the Hiigarans (the protagonists) during the first game. In Homeworld 2 the Hiigarans had settled down on Hiigara and reclaimed their empire and so no longer count as a race of Space Nomads.
  • The semi-canonical Expansion PackHomeworld: Cataclysm could possibly say the same about the Somtaaw, whose entire Kiith left Hiigara in two huge command ships in order to become Asteroid Miners. They could return to Hiigara and settle down, but there is little for them there, as smaller kiithid have virtually no power on the homeworld.
• Mass Effect
  • The quarians are a perfect example of this trope. They're even based on the real-life Romani people (gypsies), who were historically a nomadic folk that migrated from India to Europe. If you make the right choices in the third game, they return to their original homeworld and settle down.
  • The eealen race in the Andromeda galaxy took to wandering the stars and sharing knowledge after their war with the Kett Empire reduced their population to below the point of viability.
• Metroid Prime 2: Echoes: The Luminoth are mentioned in their lore to have been this for a long time before settling down on Aether.
• Rodina: It's likely that the enemy aliens are this, considering they only exist in ships in orbit and have no cities or structures on any of the planets.
• Sins of a Solar Empire: The Vasari, who only briefly take over planets to strip them of resources before leaving again. If you play as the Vasari Loyalists this is even reflected in the game mechanics where you can move all your planet-based facilities such as resource gathering, research and ship-building onto your capital ships and become a fully mobile force.
• Star Ruler 2: The Nylli do not inhabit planets, and instead reside solely in space, either in orbital habitats or in their absolutely massive motherships which moves between solar systems, seeding planets with habitat constructors.
• Stellaris:
  • One may encounter nomads who peacefully wander through space. Once contact is established, they can put you into contact with other empires they encounter.
  • If the Megacorp DLC is installed, the nomads are replaced with Caravaneers, whose fleets make circuits around the galaxy offering trade deals with empires they pass through, periodically returning to a system called 'Chor's Compass' to trade with one another.
• Sword of the Stars: Half of the Morrigi population lives this way. The male half, to be specific; Morrigi culture mandates that male and female offspring be divided into gender-segregated communities in early infancy. Male Morrigi spend their lives from infancy to senescence in space, living aboard nomadic starships which travel constantly from star to star. Female Morrigi are terrestrial creatures for the duration of their lives, raised in full gravity and adapted accordingly to planetary conditions.
• Meteos has a couple of examples:
  • Darthvega is a massive octahedral spaceship that travels more or less aimlessly through space. They built the spaceship, and the entire planet's population went on board for unknown reasons. Though it resembles the Death Star and the inhabitants look like devils, they're a peaceful people.
  • Suburbion is a fleet of cities in floating domes, though in this case, the Suburbions destroyed their own planet by warfare and live in this fleet due to having nowhere else to live.

• Orion's Arm:
  • Worldships are immense vessels designed to be permanently inhabited — a ship eight kilometers long and with 400,000 permanent inhabitants is considered on the small side — and to move near-constantly at a few fractions of light speed, enough for relativistic distortion not to be an issue. They wander around between star systems, stopping briefly at each port of call to exchange goods and information before moving on. They usually contain entire, self-sufficient environments within themselves and, due to the amount of time they spend in isolation, tend to be home to unique and sometimes bizarre cultures.
  • The Civilization Ships are a particularly notorious example in-universe, being titanically large vessels — 400 kilometers long and 120 wide — built after a disastrous interstellar war to serve as failsafes in case interstellar civilization should ever go belly-up. They're nearly indestructible spaceborne fortresses loaded with sapient and post-sapient inhabitants, alongside immense stores of information and artifacts, in order to be able to restart civilization in case of disaster. There are over a hundred in existence, which travel slowly between the stars — they're way too large to use the wormhole networks most others travel — and occasionally stopping at inhabited system to pick up valuable artifacts and refresh their information stores.
  • The Eh'ern, an alien species from the Triangulum Galaxy, lived for the most part in immense, spaceborne trees that were often fitted with reactionless drives and turned into interstellar ships. These communities tended to become interstellar nomads, moving from star system to star system as the mood struck them.

• Ben 10: In 'The Big Tick', the villain-of-the-week is a gigantic spaceborne tick which travels from world to world, sucking each one dry to the core and reducing it to desolation — and it's apparently responsible for destroying the homeworld of Cannonbolt's species very recently.
• Wakfu: The Eliatropes (and the Council of Six's dragon siblings) were Space Nomads after the exodus from their homeworld aboard their spaceship the Zinit, before they settled on the World of Twelve. Qilby wants his people to return to being Space Nomads so he'll never be bored with having to live on just one world — never mind that the Zinit needs to drain planetarylevels of wakfu just to get off the ground.
• Wander over Yonder: The titular Wander goes from planet to planet helping those in need, and has no known home or planet to call his own. He typically spends the night on whatever planet he is on, or even in Lord Hater's ship sometimes.
