If you have recently updated to 10.10.x (Yosemite) from a previous version of OS 10.x.x [and you were successfully using your CAC], you might need to uninstall your CAC enabling program, restart computer, then install an updated version of your CAC enabler. Look at the CAC enablers page to find out which enablers are compatible with 10.10.x
If you are having DTS (Defense Travel System) problems with Yosemite, please look here
The following information is provided for your situational awareness while setting up the utilization of your CAC on your Mac. It is updated as additional information is available and your input is appreciated for solutions not outlined here. Installation instructions can be found below.
ActivClient is a middleware program used by the DoD to facilitate the cross talk between Windows computers and your Common Access Card. It was offered for the “Tiger” release (Mac OS X 10.4.x) and is not compatible with Lion (the current release of Mac OS X (10.7.x)). The program is available for purchase through the manufacturer, and is not available for download from DoD. The use of this program is not supported here for Apple operating systems, as it is not required and won't work with Mountain Lion (10.8.x).
Army has migrated to Adobe fillable forms. Army Publishing Directorate began the conversion of the Army's inventory of existing IBM Lotus forms to PDF-F in FY 2014. Beginning in FY15, Lotus Forms and ApproveIt / eSign software will no longer be supported. This is great news for Mac users since Lotus and ApproveIt has never worked for them, however, we have come to find out that we are still unable to sign the forms.
NOTICE: The links to vendors / products is an attempt to save you time searching for the specific item, by linking you directly to the item shown. You will notice I have multiple [when I can find] vendors to choose from. I have no personal preference as to who you decide to purchase from. I am not endorsing any particular product, I'm merely letting you know what works and where you can get it from.
Windows on your Mac: (You MUST have an Intel processor, it will NOT work with a PPC processor): We know you have made a conscious decision to “be a Mac,” but the Government / Microsoft have not. DTS, and signing forms used to only be available to Windows users, but are now available to you. The last item you cannot do on a Mac is to digitally encrypt and / or decrypt emails in OWA. To do this, you'll need to use Windows through a Virtual Machine, such as Parallels (discounted prices), VMware Fusion (Parallels vs. VMware comparison), or VirtualBox or through Apple’s native Boot Camp (alternate guide). This will require you to have a licensed copy of Microsoft Windows, install the DoD certificates, and make sure your Internet Explorer web browser is configured correctly. With these programs, you can install the S/MIME control software within your web browser. The benefit of the Virtual Machines over Boot Camp is that it will allow you to run Windows as an additional program (without restarting your computer) and keep OS X running the entire time.
Discounted prices on these programs below can be viewed here
NOTE: If your CAC reader is not being recognized by your virtual Windows, follow this guidance:
VMware Fusion: From the menu bar, select Virtual Machine, then USB. Find your CAC reader and select it.
Parallels Desktop - (In Coherent mode): Click the red parallel lines in the menu bar, Select Devices, USB, find your CAC reader and select it.
Parallels Desktop - (Not in Coherent mode): Simply plug your reader into the computer and select whether you want to use it in Mac or Windows. You may also need to click the word Devices in the top row, USB, then your CAC reader.
VirtualBox: Click the word Devices (at the top of the screen), then USB Devices, and select your CAC reader. When you want to use it on your Mac, go to the same location and remove the checkmark. If you receive an error message when trying to select the reader here follow these instructions:
* In the VirtualBox GUI, click on USB (small icon in
the list of devices).
DTS (Defense Travel System) See the DTS specific page for support
CAC Readers: With a variety of CAC readers available today there are also a variety of issues. The SCR series of CAC readers work very well. The SCR-331 reader may need a Firmware Update. See several different models of USB CAC readers here. You will see a small note on some of the readers to show you how to make them compatible with your Mac. Here is a web page that lists all known CAC readers and whether they are supported, should work, or unsupported with the Mac OS'.
HQDA Citrix access information for your Mac How to guide
DoD Root certificates on your Mac only go up to CA 26, so, if your CAC has a CA between 27-32 you need to install all of the CAs 27-32 and CA Email 27-32. You can download the AllCerts.zip file, then double click each certificate in the folder.
Outlook Web Access / App (OWA): The use of OWA on Mac sometimes times out. Beware that when using OWA on your Mac if you are inactive on the primary window, for example: the Inbox, while replying to an email, the browser may time out. On a Windows computer ActivClient (middleware) software maintains communications with the server and re-requests validation of your credentials. On a Mac this is not so, Safari will respond to a direct request for validation of your credentials, however it will not re-request that you verify as the server requires. Be sure that prior to selecting the Send button that you copy your work to the clipboard as you will most likely have to restart Safari and log back in. You also will not be able to digitally sign / encrypt / decrypt emails since the S/MIME software is proprietary for Microsoft Internet Explorer (32 bit) only, therefore, it doesn't exist for a Mac.
Internet Explorer Emulation (NOT applicable to OWA): If you visit a website with your Mac that states it can only be accessed via Internet Explorer, or some web pages simply won't work while using your CAC with Safari, try this: Open Safari, Click on the word Safari (in the bar at the top), select Preferences..., Advanced, click the Show Develop menu in the menu bar box. Close Advanced screen. Now to emulate IE, click on the word Develop (at the top), click User Agent, then choose Internet Explorer 9, 10, or 11.
