MacOS is the operating system that powers every Mac. It lets you do things you simply can’t with other computers. That’s because it’s designed specifically for the hardware it runs on —.

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)
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)
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.

What is the Mac swapfile? Is it important? Can you delete it? We’ll walk you through this mysterious Mac file and what you can do about it.
If you’ve even run out of disk space on your Mac, you’ve probably sat and taken some time to look and see what’s eating up all this space (pro tip: it’s easy to forget how many files you move to the Mac Trash folder; the first thing you should do when you run out of space is right-click on the Trash icon on the dock and select Empty Trash).

Mac Os For Notebooks Windows 10

You might have run across something called swap, or a swapfile. It can be difficult to understand just what these files are, and whether you can manage to do without them, especially since they seem to just sit there and take up space; sometimes they take up quite a lot of space indeed.

What is the Mac swapfile?

Before we delve into what the swapfile is, we have to talk about swapping in the context of how your computer works. When you run a program on your Mac, it gets loaded into your memory (RAM). You have a much smaller amount of RAM than you do storage on your SSD.
Occasionally, if you’re doing something that requires a lot of memory, you’ll come up against some of the limits that come with having limited RAM. Enter paging. Paging is what we call using your storage drive as memory. It’s all done automatically by your computer, so you never tend to notice when it happens. While the terms originally meant something different, these days paging and swapping are largely synonymous.
When you write something to your disk, it isn’t always written in contiguous stretches of storage; instead it might be written in a number of places, wherever your Mac (PCs do this, too) finds an open spot.

In order for swapping to work, your Mac usually needs one of those contiguous stretches, which can be difficult to find on a drive as it increasingly fills up with data. To mitigate this, OS X will generate a number of these swapfiles so that it can write (or page, or swap) to them whenever it needs them.
You can find them by navigating to an arcane folder deep within the bowels of your Mac. Just click on an open part of your desktop and mouse up to the bar at the top of your screen. Click on Go, and in the drop-down menu, click on Go to Folder.

Mac Notebook App

A box will appear with an address bar in it; you’ll want to copy and paste the following location into it: /private/var/vm/ and hit enter. Finder will pop up with a new window listing the swapfiles your Mac currently has active.
How many files appear depend on a number of factors: how much and how often the Mac has needed to swap to your storage drive (which itself will depend on how much memory you have and how many programs you use that may have memory leaks). For reference, the above swapfiles were generated on a Macbook Pro with 16GB of RAM; it’s gone around ten days since it was last rebooted.

Can you delete Mac swapfiles?

Yes, you can delete them. You can even tell your Mac to never swap again. But you shouldn’t. Even on systems that have a lot of memory, your Mac might find a need to swap to its storage space instead of use its primary memory, or RAM.
If you delete your swapfiles, you might cause your system to crash, as it’s possible that your Mac is using one of them right as you delete it. The same goes for whether you should disable the ability for your Mac to use swapfiles in the first place – the best result is that you won’t notice a difference, and it’s more likely to make your Mac increasingly unstable.

Apple Mac Notebook

If you really need to free up some space taken up by your Mac’s swapfiles, there’s an easy and simple fix: just reboot your Mac. Shut it down and restart it, and then check your swapfile directory again – they should either be gone or substantially reduced in size.
Chances are good that on a new Mac you’re unlikely to run into issues where your swap is seriously impacting how much free space you have. Should you keep running into an issue, however, take a look at the apps you run on a regular basis, and try playing around with them one at a time. You might find that one app has a memory leak, and by rebooting after use or finding an alternative app, you can avoid the big swapfile issue altogether!
