This compression and password protection is agnostic to the desktop operating system so you can send it to Window users, Linux users and of course Mac users. Let us know what other ways you use compression and password protection of your files on macOS in the comments. In a recent third party evaluation by AV Test on SentinelOne’s ability to prevent cyber threats on the Mac platform, it was lauded for its ability to “fend off all attackers 100 percent, resulting only in an additional system load of one second.” Compared to competitive products, SentinelOne’s protection requires three to five percent. Mac users are typically okay with the protections included in macOS, especially if you download software only from Apple’s App Store and stick to well-known browser extensions.

2. Protect The Little One Mac Os Download

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

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 10.4 - 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

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.

Mountain View, Calif. – Feb. 12, 2017 – SentinelOne, the autonomous endpoint protection company, today announced it will integrate its SentinelOne Endpoint Protection Platform (EPP) with Windows Defender Advanced Threat Protection (ATP) service to cover Mac and Linux device platforms. SentinelOne will seamlessly feed all threats and detections from Mac and Linux endpoints into the Windows Defender ATP console, enabling security teams to see and remediate threats across Windows, Mac, and Linux platforms. To sign up for beta access, please visit https://go.sentinelone.com/Microsoft-WD-ATP-Onboarding.html.

Organizations are not homogeneous in their devices, often using computers, operating systems and servers from a variety of vendors. As a result, unified cross-platform protection and visibility into threats across all platforms and devices is more important than ever before. With SentinelOne’s integration with Windows Defender ATP, security teams can now detect, prevent and respond to attacks on MacOS and Linux OS devices natively from the Windows Defender ATP console.

“SentinelOne is the only platform that autonomously defends every endpoint against every type of attack, at every stage in the threat lifecycle. Our work with Microsoft is a true testament to our efficacy, performance and visionary engineering prowess,” said Tomer Weingarden, CEO and co-founder, SentinelOne. “We are laser focused on providing the industry’s most advanced and open endpoint protection platform. This tight integration furthers our mission to secure every endpoint, and protect every edge of the network, regardless of hardware or OS.”

By applying machine learning and AI, SentinelOne Endpoint Protection Platform (EPP) proactively protects from advanced threats, as well as detects and remediates endpoint issues fully automatically. SentinelOne’s Behavioral AI engine monitors each system process providing not only superior protection from the widest array of attack vectors, but also yielding unparalleled endpoint visibility.

Within the Windows Defender ATP console, every device has its own rich machine timeline, with event history for up to six months that can be instantaneously and easily searched as well as actioned. SentinelOne customers can easily integrate with Windows Defender ATP and implement the service with just a few clicks. There are no requirements for any additional infrastructure, and once the integration is configured, new events from onboarded MacOS and Linux devices start natively surfacing into the Windows Defender ATP console.

“In a modern security environment, security teams need to monitor a variety of devices, including Windows, Linux and MacOS platforms.” said Moti Gindi, General Manager for Windows Cyber Defense, Microsoft. “SentinelOne’s solution integrates with Windows Defender ATP to monitor Mac and Linux endpoints’ activity and apply machine learning to dynamically detect attacks in real-time. This provides customers with a single integrated view of their endpoints security across platforms.”

SentinelOne is consistently rated the top EPP product by customers, leading AV testing organizations and received a “recommended” rating for Advanced Endpoint Protection from NSS Labs. In a recent third party evaluation by AV Test on SentinelOne’s ability to prevent cyber threats on the Mac platform, it was lauded for its ability to “fend off all attackers 100 percent, resulting only in an additional system load of one second.” Compared to competitive products, SentinelOne’s protection requires three to five percent less resources.

Beta access to the integrated SentinelOne/Windows Defender ATP solution is now available.
