Processor, memory and operating system To find your Mac's basic specs, click the Apple icon in the top left corner of your screen. From the drop-down menu, click About This Mac to open the System. Up until now Apple’s OS for their Macs has been called OS X, but things have changed. From now on it will be called macOS, and Sierra is the name of the version of the OS that the company has launched this year. The new name matches with the company’s other OSes – watchOS, tvOS, and iOS. MacOS Sierra Brings Siri to the Mac. The new Mac operating system offers more than a name change. MacOS Sierra version 10.12 moves Apple's desktop OS closer to its mobile counterpart, gaining Siri, Apple Pay, and more.

Check compatibility

If a macOS installer can't be used on your Mac, the installer will let you know. For example, it may state that your Mac doesn't have enough free storage space for the installation or that the installer is too old to be opened on this version of macOS.

If you want to check compatibility before downloading the installer, find out more about the minimum requirements for macOS Catalina, Mojave, High Sierra, Sierra, El Capitan or Yosemite. You can also check compatible operating systems on the product ID page for MacBook Pro, MacBook Air, MacBook, iMac, Mac mini or Mac Pro.

Make a backup

Before installing, it’s a good idea to back up your Mac. Time Machine makes it simple, and other backup methods are also available. Find out how to back up your Mac.

Download macOS

It takes time to download and install macOS, so make sure you're plugged into AC power and have a reliable Internet connection.

These installers from the App Store will open automatically after you've downloaded them:

  • macOS Catalina 10.15 can upgrade Mojave, High Sierra, Sierra, El Capitan, Yosemite or Mavericks
  • macOS Mojave 10.14 can upgrade High Sierra, Sierra, El Capitan, Yosemite, Mavericks or Mountain Lion
  • macOS High Sierra 10.13 can upgrade Sierra, El Capitan, Yosemite, Mavericks, Mountain Lion or Lion

Your web browser will download the following older installers as a disk image called InstallOS.dmg or InstallMacOSX.dmg. Open the disk image, then open the .pkg installer inside the disk image. It will install an app named Install [Version Name]. Open that app from your Applications folder to start installing the operating system.

  • macOS Sierra 10.12 can upgrade El Capitan, Yosemite, Mavericks, Mountain Lion or Lion
  • OS X El Capitan 10.11 can upgrade Yosemite, Mavericks, Mountain Lion, Lion or Snow Leopard
  • OS X Yosemite 10.10can upgrade Mavericks, Mountain Lion, Lion or Snow Leopard

Install macOS

Follow the onscreen instructions in the installer. It may be easiest to start the installation in the evening so that it can be completed overnight, if needed.

If the installer asks for permission to install a helper tool, enter the administrator name and password that you use to log in to your Mac, then click Add Helper.

Please allow installation to complete without putting your Mac to sleep or closing its lid. Your Mac might restart, show a progress bar or show a blank screen several times as it installs both macOS and related updates to your Mac firmware.

You may also be able to use macOS Recovery to reinstall the macOS you're using now, upgrade to the latest compatible macOS, or install the macOS that came with your Mac.

NOTE:

Between mid October 2019 and mid February 2020 everyone in the Army was migrated to use their PIV Authentication certificate for Email access. You no longer use the Email certificate for Enterprise Email or any CAC enabled websites

Mac users who choose to upgrade (or already have upgraded) to Mac OS Catalina (10.15.x) will need to uninstall all 3rd Party CAC enablers per https://militarycac.com/macuninstall.htm AND reenable the built in smart card ability (very bottom of macuninstall link above)

If you purchased your Mac with OS Catalina (10.15.x) already installed, you can skip the uninstall part above and follow the instructions below.

6 'high level' steps needed, follow down the page to make this a painless systematic process

1.Is your CAC reader 'Mac friendly'?
2.Can your Mac 'see' the reader?
3.Verify which version of Mac OS you have
4.Figure out which CAC (ID card) you have
5.Install the DoD certificates
5a.Additional DoD certificate installation instructions for Firefox users
6.Decide which CAC enabler you want to use (except for 10.12-.15 & 11)

Step 1: Is your CAC reader Mac friendly?

Visit the USB Readers page to verify the CAC reader you have is Mac friendly.

Visit the USB-C Readers page to verify the CAC reader you have is Mac friendly.

'Some, not all' CAC readers may need to have a driver installed to make it work.

NOTE: Readers such as: SCR-331 & SCR-3500A may need a firmware update (NO OTHER Readers need firmware updates).

Information about these specific readers are in Step 2

Step 2: Can your Mac 'see' the reader?

Plug the CAC reader into an open USB port before proceeding, give it a few moments to install

Step 2a: Click the Apple Icon in the upper left corner of the desktop, select 'About This Mac'

Step 2b: Click 'System Report...' (button)

Step 2c: Verify the CAC reader shows in Hardware, USB, under USB Device Tree. Different readers will show differently, most readers have no problem in this step. See Step 2c1 for specific reader issues.

Step 2c1: Verify firmware version on your SCR-331 or GSR-202, 202V, 203 CAC, or SCR-3500a reader. If you have a reader other than these 5, Proceed directly to step 3

Step 2c1a-SCR-331 reader

If your reader does not look like this, go to the next step.

In the 'Hardware' drop down, click 'USB.' On the right side of the screen under 'USB Device Tree' the window will display all hardware plugged into the USB ports on your Mac. Look for “SCRx31 USB Smart Card Reader.” If the Smart Card reader is present, look at 'Version' in the lower right corner of this box: If you have a number below 5.25, you need to update your firmware to 5.25. If you are already at 5.25, your reader is installed on your system, and no further hardware changes are required. You can now Quit System Profiler and continue to Step 3.

Step 2c1b-SCR-3500A reader

If you have the SCR3500A P/N:905430-1 CAC reader,you may need to install this driver, as the one that installs automatically will not work on most Macs. Hold the control key [on your keyboard] when clicking the .pkg file [with your mouse], select [the word] Open

Step 3: Verify which version of MacOS do you have?

(You need to know this information for step 6)

Identify

Step 3a: Click the Apple Icon in the upper left corner of your desktop and select 'About This Mac'

Step 3b: Look below Mac OS X for: Example: Version 10.X.X.

Step 4: Figure out which CAC (ID Card) you have

(You need to know this information for step 6)

Look at the top back of your ID card for these card types. If you have any version other than the six shown below, you need to visit an ID card office and have it replaced. All CACs [other than these six] were supposed to be replaced prior to 1 October 2012.

Please know... IF You have any DoD certificates already located in your keychain access, you will need to delete them prior to running the AllCerts.p7b file below.

https://militarycac.com/maccerts/AllCerts.p7b,

https://militarycac.com/maccerts/RootCert2.cer,

https://militarycac.com/maccerts/RootCert3.cer,

https://militarycac.com/maccerts/RootCert4.cer, and

Double click each of the files to install certificates into the login section of keychain

Select the Kind column, verify the arrow is pointing up, scroll down to certificate, look for all of the following certificates:

DOD ID SW CA-45 through DOD ID SW CA-48,

DoD Root CA 2 through DoD Root CA 5,

DOD SW CA-53 through DOD SW CA-58, and

DOD SW CA-60 through DOD SW CA-61

NOTE: If you are missing any of the above certificates, you have 2 choices,

1. Delete all of them, and re-run the 5 files above, or

2. Download the allcerts.zip file and install each of the certificates you are missing individually.

Errors:

Error 100001 Solution

Error 100013 Solution

You may notice some of the certificates will have a red circle with a white X . This means your computer does not trust those certificates

You need to manually trust the DoD Root CA 2, 3, 4, & 5 certificates

Double click each of the DoD Root CA certificates, select the triangle next to Trust, in the When using this certificate: select Always Trust, repeat until all 4 do not have the red circle with a white X.

You may be prompted to enter computer password when you close the window

Once you select Always Trust, your icon will have a light blue circle with a white + on it.

The 'bad certs' that have caused problems for Windows users may show up in the keychain access section on some Macs. These need to be deleted / moved to trash.

The DoD Root CA 2 & 3 you are removing has a light blue frame, leave the yellow frame version. The icons may or may not have a red circle with the white x

or DoD Interoperability Root CA 1 or CA 2 certificate
DoD Root CA 2 or 3 (light blue frame ONLY) certificate
or Federal Bridge CA 2016 or 2013 certificate
or Federal Common Policy CAcertificate
or or SHA-1 Federal Root CA G2 certificate
or US DoD CCEB Interoperability Root CA 1 certificate
