AdLoad is malicious software that targets macOS operating systems. It is capable of avoiding detection by built-in macOS security tools and a number of third party antivirus programs and other security suites of this type. Furthermore, it prevents victims from removing the software from operating systems. AdLoad is adware-type malware that hijacks browsers and forces users to visit potentially malicious websites. This enables cyber criminals to generate revenue .
Research shows that AdLoad is not the only name used for this malware. It is also known by Kreberisec, ApolloSearchDaemon, AphroditeResults, NetSignalSearchDaemon, ApolloSearch, and many others. We have provided a list of alternative names below. This adware-type malware often has 'SearchDaemon', 'Lookup', 'DataSearch' and 'Results' within its name. AdLoad stores its files in various directories. Some of these files can be found easily, whilst others are more elusive. In any case, it can only perform these actions when the victim provides the password of an admin account. This malware stores its two LaunchDaemon files in the local domain Library and the LaunchAgent file in the local user Library. For example, if this malware uses the 'DataSearch' name, it stores 'com.DataSearch.plist' in '~/Library/LaunchAgents/' and targets the executable file in '~/Library/Application Support/com.DataSearch/DataSearch'. It then stores 'com.DataSearchDaemon.plist' in '~/Library/LaunchDaemons/', which targets '~/Library/Application Support/com.DataSearchDaemon/DataSearch' and 'com.DataSearchP.plist' in '~/Library/LaunchDaemons/' - this targets a Mach-O executable 'DataSearchDaemon' in '/var/root/.SearchQuest/DataSearchDaemon'. The last item calls a python script ('DataSearch.py'), which opens a connection with a remote host. To maintain persistence, DataSearch also creates a hidden directory ('/var/root/.mitmproxy'). Moreover, this malware installs user cronjob and an executable in a subfolder of the victim's Library Application Support folder. Injected code is designed to run every two hours and thirty minutes. People who have AdLoad installed on their macOS systems involuntary help cyber criminals to generate revenue by being forced to visit various websites, which are preferred by the attackers.

Manual removal of AdLoad malware can be a difficult task. All components must be removed such as launch agent, daemon, cron job files, and processes in '/var/root'. It is very likely that AdLoad will rewrite/recreate these during its manual removal process, however, repeatedly removing the aforementioned files and processes should eventually eliminate AdLoad malware from the system.
AdLoad is distributed through various rogue installers of potentially unwanted applications (PUAs) and adware. For example, via installation set-ups of fake Flash Players. Typically, these installers are distributed through unofficial, deceptive, scam websites - these trick people into downloading and executing a setup file that installs unwanted/malicious software, including adware-type malware such as AdLoad.
To protect systems from installation of malicious software, do not download software, files, or any content from unofficial websites, using Peer-to-Peer networks (torrent clients, eMule), third party downloaders, and so on. The only safe way to download files and programs is using official websites. If a download or installation set-ups contains settings such as 'Custom', 'Advanced', etc., check them carefully and dismiss offers to download and/or install additional (unwanted) software. Do not update software using fake, unofficial updaters that were downloaded from dubious web pages. We strongly recommend that you update installed software through tools and/or implemented functions designed by official developers. Do not click intrusive ads, especially if displayed on dubious web pages - they often lead to dubious sites that trick people into installing unwanted software, or they run scripts that download and install it. Scan the operating system with reputable antivirus software regularly and ensure that it is up to date. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for macOS to automatically eliminate them.

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.
We’ll be repeatedly referring to these Apple OS versions below, so it’s good to know the basic macOS timeline.
Cheetah 10.0 | Puma 10.1 | Jaguar 10.2 |
Panther 10.3 | Tiger 10.4 | Leopard 10.5 |
Snow Leopard 10.6 | Lion 10.7 | Mountain Lion 10.8 |
Mavericks 10.9 | Yosemite 10.10 | El Capitan 10.11 |
Sierra 10.12 | High Sierra 10.13 | Mojave 10.14 |
Catalina 10.15 |
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:
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.

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