Wizards Scourge 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.

Nearly perfect I have a specific usage case - I work in a multiplatform environment in which I work on the Mac and on the PC. I don't want to keep changing physical keyboards, so despite the fact that the two physical machines are next to eachother beneath my desk, I use remote desktop to view and operate the PC while working on the Mac. In the Assets and Compliance workspace, start the Create Configuration Item Wizard. On the General page, specify the following information. Name:Remove SMSID for Mac. On the Supported Platforms page, ensure that all macOS X versions are selected. On the Settings page, choose New and then, in the Create Setting dialog box, specify the following information.
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 |
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:
- Click the App Store icon.
- Click Purchases in the top menu.
- Scroll down to find the preferred OS X version.
- 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.
- Start your Mac holding down Command + R.
- Prepare a clean external drive (at least 10 GB of storage).
- Within OS X Utilities, choose Reinstall OS X.
- Select external drive as a source.
- 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.
- Boot your Mac from your standard drive.
- Connect the external drive.
- 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.
Applies to: Configuration Manager (current branch)
Here are procedures for uninstalling Mac clients and for renewing their certificates.
Uninstalling the Mac client
On a Mac computer, open a terminal window and navigate to the folder containing macclient.dmg.
Navigate to the Tools folder and enter the following command-line:
./CMUninstall -c
Note
The -c property instructs the client uninstall to also remove client crash logs and log files. We recommend this to avoid confusion if you later reinstall the client.
If required, manually remove the client authentication certificate that Configuration Manager was using, or revoke it. CMUnistall does not remove or revoke this certificate.
Renewing the Mac client certificate
Use one of the following methods to renew the Mac client certificate:
Scourge Wizard Build
Renew certificate wizard
Configure the following values as strings in the ccmclient.plist file that controls when the Renew Certificate Wizard opens:
RenewalPeriod1 - Specifies, in seconds, the first renewal period in which users can renew the certificate. The default value is 3,888,000 seconds (45 days). Don't configure a value less than 300, as the period will revert to the default.
RenewalPeriod2 - Specifies, in seconds, the second renewal period in which users can renew the certificate. The default value is 259,200 seconds (3 days). If this value is configured and is greater than or equal to 300 seconds and is less than or equal to RenewalPeriod1, the value will be used. If RenewalPeriod1 is greater than 3 days, a value of 3 days will be used for RenewalPeriod2. If RenewalPeriod1 is less than 3 days, then RenewalPeriod2 is set to the same value as RenewalPeriod1.
RenewalReminderInterval1 - Specifies, in seconds, the frequency at which the Renew Certificate Wizard will be displayed to users during the first renewal period. The default value is 86,400 seconds (1 day). If RenewalReminderInterval1 is greater than 300 seconds and less than the value configured for RenewalPeriod1, then the configured value will be used. Otherwise, the default value of 1 day will be used.
RenewalReminderInterval2 - Specifies, in seconds the frequency at which the Renew Certificate Wizard will be displayed to users during the second renewal period. The default value is 28,800 seconds (8 hours). If RenewalReminderInterval2 is greater than 300 seconds, less than or equal to RenewalReminderInterval1 and less than or equal to RenewalPeriod2, then the configured value will be used. Otherwise, a value of 8 hours will be used.
Example: If the values are left as their defaults, 45 days before the certificate expires, the wizard will open every 24 hours. Within 3 days of the certificate expiring, the wizard will open every 8 hours.
Example: Use the following command line, or a script, to set the first renewal period to 20 days.
sudo defaults write com.microsoft.ccmclient RenewalPeriod1 1728000
When the Renew Certificate Wizard opens, the User name and Server name fields will typically be pre-populated and the user can just enter a password to renew the certificate.
Note
If the wizard does not open, or if you accidentally close the wizard, click Renew from the Configuration Manager preference page to open the wizard.
Renew certificate manually
A typical validity period for the Mac client certificate is 1 year. Configuration Manager does not automatically renew the user certificate that it requests during enrollment, so you must use the following procedure to renew the certificate manually.
Wizards Scourge Mac Os Catalina
Important
If the certificate expires, you must uninstall, reinstall and then re-enroll the Mac client.
Wizards Scourge Mac Os X
This procedure removes the SMSID, which is required to request a new certificate for the same Mac computer. When you remove and replace the client SMSID, any stored client history such as inventory is deleted after you delete the client from the Configuration Manager console.
Create and populate a device collection for the Mac computers that must renew the user certificates.
Warning
Configuration Manager does not monitor the validity period of the certificate that it enrolls for Mac computers. You must monitor this independently from Configuration Manager to identify the Mac computers to add to this collection.
In the Assets and Compliance workspace, start the Create Configuration Item Wizard.
On the General page, specify the following information:
Name:Remove SMSID for Mac
Type:Mac OS X
On the Supported Platforms page, ensure that all macOS X versions are selected.
On the Settings page, choose New and then, in the Create Setting dialog box, specify the following information:
Name:Remove SMSID for Mac
Setting type:Script
Data type:String
In the Create Setting dialog box, for Discovery script, choose Add script to specify a script that discovers Mac computers with an SMSID configured.
In the Edit Discovery Script dialog box, enter the following Shell Script:
Choose OK to close the Edit Discovery Script dialog box.
In the Create Setting dialog box, for Remediation script (optional), choose Add script to specify a script that removes the SMSID when it is found on Mac computers.
In the Create Remediation Script dialog box, enter the following Shell Script:
Choose OK to close the Create Remediation Script dialog box.
On the Compliance Rules page of the wizard, click New, and then in the Create Rule dialog box, specify the following information:
Name:Remove SMSID for Mac
Selected setting: Choose Browse and then select the discovery script that you specified previously.
In the following values field, enter The domain/default pair of (com.microsoft.ccmclient, SMSID) does not exist.
Enable the option Run the specified remediation script when this setting is noncompliant.
Complete the Create Configuration Item Wizard.
Create a configuration baseline that contains the configuration item that you have just created and deploy it to the device collection that you created in step 1.
For more information about how to create and deploy configuration baselines, see How to create configuration baselines and How to deploy configuration baselines.
On Mac computers that have the SMSID removed, run the following command to install a new certificate:
When prompted, provide the password for the super user account to run the command and then the password for the Active Directory user account.
To limit the enrolled certificate to Configuration Manager, on the Mac computer, open a terminal window and make the following changes:
a. Enter the command
sudo /Applications/Utilities/Keychain Access.app/Contents/MacOS/Keychain Access
b. In the Keychain Access dialog, in the Keychains section, choose System, and then, in the Category section, choose Keys.
c. Expand the keys to view the client certificates. When you have identified the certificate with a private key that you have just installed, double-click the key.
d. On the Access Control tab, choose Confirm before allowing access.
e. Browse to /Library/Application Support/Microsoft/CCM, select CCMClient, and then choose Add.
f. Choose Save Changes and close the Keychain Access dialog box.
Restart the Mac computer.
