1. Ldjam 45 - Shipwrecked Mac Os Update

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.

Mac OS X Snow Leopard launched in 2009 as Intel only. To move the entirety of the Mac platform for millions of users, minuscule by today's user base, to a new system architecture with minimal.

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.

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

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.

It's time for another chipset transition for the Mac, this time from Intel to ARM. Apple announced their transition to Apple Silicon during WWDC 2020 and they aim to be finished within two years. This page shows the rumors leading up to the announcement of the official transition.

● Custom Apple Silicon
● New ARM friendly macOS Big Sur
● Based on existing A-series processors
● Software already exists
● Control over entire stack
● Leave legacy software behind
● Apple Developer Transition Kit

Pre-WWDC 2020 page: Go to Apple Silicon for information about Apple's transition plan and their custom processors. This page will remain for reference to rumors and leaks leading up to the announcement.

Software shifts and hardware transitions are nothing new to Apple, and we are about to see another huge shift in how they approach consumer technology. Until now, the Mac has relied on innovation and development from Intel to move forward, but with the ARM Mac, Apple will have total control.

Rumors have circulated for a few years now about the potential of an ARM-based Mac. With the introduction of the iPad Pro and continued year-over-year improvements to Apple’s A-series chipsets, an ARM Mac feels almost inevitable.

The past decade has been bumpy for Mac users. Apple has had its own host of issues with designs they introduced, like the butterfly keyboard and cylindrical Mac Pro, but much of what has been holding back the Mac falls on Intel.

Since 2015 Intel has seen marginal improvements in their chipset capabilities and relied upon increased clock speeds and more demands on cooling than actual processor gains. This left Apple with little room to move when it came to innovating on the Mac platform.

Apple even had to implement custom silicon in their Macs to run in tandem with the Intel processors, thus taking some of the load off of the Intel processes.

If Apple controlled the development of all the hardware and software in Mac, just as it has with the iPhone and iPad, then we would see much greater leaps in performance over time. This would allow more room for innovations in design and add in additional use cases and hardware.

Since the release of macOS Catalina, we have seen a slow trickle of Mac Catalyst apps. These are apps designed for iPad that have been formatted to work on Macs with macOS system architecture and Intel chipsets.

While Catalyst has yet to prove a great hit with developers, it lays the groundwork necessary for them to start programming iPad apps as if they were running in a macOS environment.

It is safe to assume that Mac Catalyst developed iPad apps will be easily transitioned, if not directly portable, to an ARM Mac. Catalyst also shows that Apple is capable and learning about making it easy to implement developer tools for transitions between platforms.

Do not be surprised if we see a “Mac Catalyst ARM edition” of some kind very soon.

Perhaps the most crucial development surrounding software for the ARM Mac is SwiftUI. This new language is universal and can easily be used for any Apple Platform during development.

In 2005, late Apple CEO Steve Jobs announced that the Mac would transition to Intel from PowerPC over a year starting in 2006. The entire Mac line transitioned to Intel processors in 2006, first ones in January, and the last in August. Mac OS X Snow Leopard launched in 2009 as Intel only.

To move the entirety of the Mac platform for millions of users, minuscule by today's user base, to a new system architecture with minimal issues was an incredible feat. It is impossible to determine the speed at which Apple will move Mac to ARM, but for everyday users, the transition will likely be invisible.

Today's ARM chipsets can already handle most tasks an average user performs, and not having compatibility with Windows shouldn’t be an issue in a world where most data is in the cloud anyway. We do not know what kind of performance an Apple-designed “desktop-class” ARM chipset will produce, but it may be a few generations before the Mac Pro can kick Intel entirely. Lesser Macs meant for consumers and professionals who are not mapping star systems or making a Pixar movie will likely be just fine with ARM.

Apple tends to be obsessive about consistency across a platform. It is hard to imagine Apple having their entire product line from iPod to iMac running on ARM and having one single Mac on Intel. This would lead to software compatibility issues and development forks in professional-grade tools.

Even with the entire line shifting to ARM, leaving the Mac Pro as is during the transition will work fine. When you do see a Mac Pro with Apple ARM inside, expect macOS to deprecate Intel Macs soon after.

Unless you are a professional who needs to run Windows and macOS on the same machine, or have very specific software that won't update to the new ARM architecture for a few years, you won't even notice this is happening. The biggest change for more casual users will be the lockdown of compatible software.

All of the software a user downloads from the web assumes they are working on a Mac or PC running Intel. This means when you buy an ARM Mac, you will not be downloading any of that software, which might be frustrating for users. iPad and iPhone cannot download apps from the web, and the same could easily occur for the ARM Mac.

Since macOS has a bit more control over software installation, Apple will likely enable settings for users to install compatible applications from the web. It will be up to third-party developers to make their software compatible, however, and could mean a minimal third-party software for some time after launch.

If Apple is serious about an ARM transition, it will have to be behind developers all the way, and incentivize them to develop apps quickly.

If Apple restricts Mac software to the Mac App Store or makes it very hard to install from anywhere else, developers will need to offer their apps through official Apple channels. Otherwise, Apple could alienate popular developers and thus lose customers to Windows because of a lack of compatible software.

Another issue that is easily solved with licensing is Thunderbolt. Intel owns the rights to Thunderbolt and includes the necessary I/O for the ports in the Intel chipsets. Unless Apple comes up with its own version of Thunderbolt without violating patents, Apple will likely still be in business with Intel in some capacity.

Rumors point to the fall of 2020 for the first ARM Mac. The now-defunct 12-inch MacBook would make the perfect candidate for the first Mac with Apple ARM inside. Some speculate a return to the “iBook” branding for such a device since it would essentially be a MacBook running on iPad chipsets.

Reputable analyst Ming-Chi Kuo suggests a spring 2021 launch is more likely, repeatedly. Whichever is true, WWDC 2020 is the last chance for Apple to talk directly to developers about such a transition before it occurs, if it occurs before next year's WWDC.

To complicate things even further, WWDC will be held remotely via the internet in 2020 amid coronavirus concerns, making the transition announcement somewhat cumbersome as no developers will be physically present.

A developer transition kit is needed, and software too, because the hardware cannot launch without any software. It is likely that an official announcement from Apple is not far off. One Twitter leaker suggests there is a 12-inch device in development at this moment, and another leaker has since followed up stating the 12-inch ARM MacBook could be the first such product.

Another rumor corroborated the existence of a device, suggesting an ARM Mac laptop of some kind would be seen sometime in 2021. This device would host a version of the upcoming A14 chipset that is slated for the 'iPhone 12.'

Just before WWDC, Kuo released another note stating there would be an ARM MacBook by the end of 2020, with a 24-inch ARM iMac to follow.
