Literally Out Of Control (ossyahya60) Mac OS

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.

I asked him which bank and he literally called out the names of all top 5 banks in my country.

  3. The main product is 'Mac OS X', the version number is, in the latest as of this writing, 10.4.10, and the name of the version is Tiger. That makes it Mac OS X Tiger, version 10.4.10. Also, 7.5.1 was the first version to say 'Mac OS' on startup, but the name of the OS wasn't officially changed until 7.6.

A list of all Mac OS X versions

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

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.

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

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”

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.

The goal of M.A.C.E. project is the create an runtime library and executing environment for old Mac applications, similar to Apple’s deprecated Classic environment, but without needing any ROM images or System Software binaries by Apple.

Foreword

Ever since the introduction of Mac in 1984, many have been fascinated by the ease of use, friendly interface and approachability of them. Many people who only had experience of computers text-based Apple ][ and IBM-compatible PCs, were blown away by the high-resolution graphical user interface, mouse, windows, icons and everything the Macs offered. Compared to the text-based operating systems such as DOS, the step was huge – especially for kids like us who were just starting to learn English as foreign language, the switch from trying to learn typing bizarre foreign-language commands on a black terminal to a native Finnish-language visual interface, where actions were performed using pointing and clicking, was literally out of this world.

Spending youth in this environment, we grew up to love the original Mac interface, spent (way too many) hours playing the games on them, and eventually learned programming. Throughout the years, we’ve started to miss the great user experience, and games we used to play. Luckily, there also seem to be other people with more or less similar thoughts, as we found about various emulators which allowed running old Mac system software, apps and those games we used to love. The emulators we’ve most had experience have been (links included):

They all have their advantages and drawbacks, but have been the best options available so far.

From a small great idea…

Most of the emulators seemed to suffer though from certain drawbacks; most required copyrighted Apple ROM files, system software images, and transferring files required often joggling around with disk images to get the job done. And like on real Macs, it’s often not obvious which games should be ran of which system; Trying to run very old monochrome games such as Dark Castle will definitely cause problems on Mac OS 9!

Inspired by Apple’s Classic environment on Mac OS X, and further motivated by the discontinuation of it eventually during Intel transition, my friend Pukka had an idea, which turned out to be the seed from which this project was sprung from. As far back as in early 2010, he proposed building a wrapper, where “Classic” 68K Mac apps could be executed, and all their system API calls translated to the modern Carbon equivalents, called “x68k”:

Its a 68k emulator for OS X similar to what older PowerMac System/OS versions have. It is able to run old programs without classic as if they were native. For now it is only able to run simplest kind of applications.
I dont have complete Toolbox emulation (yet). There is 68k processor emulation and wrapper which translates application’s toolbox calls to the Carbon framework calls. Some deprecated functions and features are implemented so that the applications are able to run.

Sadly, the project eventually stalled due to the limitations and deprecation of Carbon API, previously started transformation Intel, and the eventual 32-bit to 64-bit transition.

…to a new beginning!

During the late 2017, I ended up chatting with Pukka, and somehow the idea of restarting the project came up. I decided I would attempt to build a completely fresh Toolbox implementation for him. Unlike the existing emulators, which are focused on emulating the hardware and using existing copyrighted ROM and operating system binaries, this project would have the benefit of being completely free of any ROM or Mac system files, with all Toolbox APIs implemented in C code, translated on the fly to the host system!

This website documents the journey we began, which could eventually lead to the ability for us to play the beloved old games, such as Dark Castle, Railroad Tycoon, and Civilization again on any modern operating systems.
